I've been exploring the Developer Community and noticed a bug.

Steps to reproduce:

1. Load home page at https://community.intersystems.com/

2. Scroll to the bottom and select a different page (e.g., 2)

3. Select a post

4. Go back with the browser

5. You should see the same page of results, but I'm seeing the first page regardless of which page I was on previously.

I think one way to address this is to change the URL when the user clicks a different page -- e.g., change it to #page2. Then this is part of their browser history. When they go back, they can hit https://community.intersystems.com/#page2, and the client-

Hello WRC.

Is possible to obtain a node-cache modul for the nodeJS ver.4.4.4. and actual Caché 2015... ?

And what is the expected outlook of this.

A note about this new portal: If I put into "search box" some text with dot like .js or .css ( for example: test.js )  , I obtaint error page. Try it.

Of course, this "Developer Community" is nice, the right way.

Nice day for all, Jan Krestyn

Hello,

I have a question about how to set the value of a radioSet.  Yes, I know -- the documentation says that setValue can be used "client side", but gives no example.  Plus, I'm trying to set the value of a radioSet in %onAfterCreatePage, which is a Zen method? Server side method? I'm not sure.

In my Zen page I create a radioSet like this:

<radioSet id="appRadio" name="appRadio" 
displayList="App One,App Two,App Three" 
valueList="One,Two,Three"/>

I want to select a radio based on a sepcific value, that I get from code.

e.g.

Method %OnAfterCreatePage() as %Status

set value = class.aMethodThatRet

Setting the TZ Environment Variable on Linux

The Update Checklist for v2015.1 recommends setting the TZ environment variable on Linux platforms and points to the manpage for tzset. This is recommended to improve the performance of Cache’s time-related functions. You can find out more about this here:

https://community.intersystems.com/post/linux-tz-environment-variable-not-being-set-and-impact-caché

The manpage on my CentOS 7 test system (RHEL 6 says the same) has this to say:

“The tzset() function initializes the tzname variable from the TZ  environment  variable.   This function is autom

Hello,

I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...

Is it possible to create a "lists/array/multidimensional 101" page for beginners? And, for instance, its interaction with $data, what it means to use "as list of something" or "as array of something", how to walk lists, how to add/remove elements, how to extract sublists etc?

At this moment, for me, this is all very confusing, and I think such a page would help me g

Hi,

I am trying to use data transformation (DTL) to map a JSON to SDA. My elements in the source JSON is not one to one with SDA object. That means I have to add code to loop through these objects in order to complete the mapping. Can someone send me a sample that can look to create that? I am not very comfortable with scripting language used in Health Share. Appreciate your help.

Regards

Joseph

I was planning to fully map out all the transforms that incoming CCDs go through before they are displayed in the Clinical Viewer or sent back to another facility.  When I opened the XSL files, I see some very good comments like the following:

I am hoping some of you network guys have ideas. InterSystems seems to be at a standstill. When I startup Studio and try to start Terminal I get License Limit Exceeded. Starting with Terminal and going to Studio, same thing. It started when I put down a 2016 version of Cache on top of a 2015. InterSystems told me to uninstall everything and start fresh. I did that but have the same problems. What can I look at? How do I start to debug this? Although I am the only one on my PC it is really impacting my performance.

Hi,

Using cube CubeA and cube CubeB that contains calculated measure TotalClients.
I would like to use TotalClient calculated measure from a compound cube CubeC (CubeA,CubeB).

How would you do that?

Hi All,

I've created a sample implementation of the MQTT protocol, which is now available on GitHub. 

The project demonstrates MQTT client capabilities and it's written in Caché Object Script.

Any comments, bug reports are welcome! Some more enhancements (like SSL / TLS support) are planned for the near future.

"Related conversations" section shows only comments number.

 In fact, these topics might also have answers.

For example, on next screenshot there are three topics in Related conversations section (on the right).

All three of them have answers, but they are shown as having 0 comments, thus seem as unanswered.

Occasionally I see a production item with a little 2 flag.  When it has that, there is an "Item" dropdown.  What does this mean?

Hello!
Are there any short ways of serializing COS entity to the string? I am searching for something like .$toJSON() , but I need Caché 2013.* support.

The one way I supposed to work is to use $listbuild:

set str = $LISTTOSTRING($LB(1,2,3,",",5))
set list = $LISTFROMSTRING(str,",")
zw list
list=$lb("1","2","3","","","5")

But the problem is that $listbuild does not escape delimiters, and it is not possible to deserialize serialized string. The structure I need to serialize may contain any characters.

Are there any short ways to do this in Caché to avoid writing custom parser?

I need to pass multiple values to a FILTER to a DeepSee DASHBOARD via the URL. The documentation seems to indicate this can be done, i.e.: "Where each filterspec is filter_name.filter_values" but there are no examples I can find that indicates what is used to separate multiple values. Say I want to pass the three values 5, 6, and 1395 to a filter. To pass just the 5 I know this works:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5

but how do I include 6 and 1395. None of the following seem to work:

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5.6.1395

&SETTINGS=FILTER:LEAD.MYUSERID.H1.MYUSERID.5,6,139

this is catching  me all the time, again and again...

Haven't worked with XML VDOC for some time, I can't figure out, what is the correct way of using Property path. Can someone please help me to refresh my memory.

Simple example: I have a class called Body, with Value and Topic properties. I created a XML Schema for this class and imported it into Ensemble. So i have a category called message, with Body as DocType structure and Name and Topic properties of Body complex type ($2:Value and $2:Topic are element names)

My rule looks this way:

However, the rule is ALWAYS evaluated as TRUE. b

Hi!

Here is small "How to" again.

Suppose you need to share something with source code. How can we manage it on DC?

Sharing code snippets

1. Add normal post (not Code Package).

2. Paste your code in the post and format it with highlighting as it is described here.

3. If you see that your COS code is highlighted wrong it means that autodetect missed with language. Open the post's HTML ("disable rich-text" button below the Editor) and put class=COS parameter into the code tag.

Example:

#dim test as %Library.Integer 
SET test = 123.099 
set ^global = %request.Content 
Write "Current 

Hi, Community!

If you prepare your longread for DC in Microsoft Word or Google Docs there is one very easy way how to add your formatted text and images in DC post at once.

To make it do the following:

1.Click Create Post on Developer Community.

2. Copy all the text in Word o GDocs to the buffer.

3. Click the button Paste from word (see the shot):

4. Paste the text to the opened window an press OK.

5. See the formatted text with images in your post. Save it as a draft or post it.

I've been in IT since 1986.

I started with Pr1me INFORMATION and Primos on Pr1me hardware.

In the 90s and 00s, I used D3.

I'm giving Caché a try, but I'm kinda having some difficulty getting started.

I've installed Caché on a 64-bit Windows 7 workstation. It was installed under an administrator's account. From a standard users account, I'm trying to access the Management Portal at:

http://localhost:57772/csp/sys/UtilHome.csp

It is prompting me for credentials. Which ones do I use? I've tried several, but nothing is working.

Problem: Caché instance connects periodically to an Oracle database via jdbc and downloads data. Sometimes data on a remote server would change.

In DeepSee, having a customer account cube. The cube includes a time dimension AccountCreationDate.

How do you create a calculated measure to get the total number of accounts from the beginning to a certain date in abscissa ?

I tried many things including this:
AGGREGATE(%TIMERANGE([AccountCreationDate].[H1].[MonthYear].&[190001],[AccountCreationDate].[H1].[MonthYear].CURRENTMEMBER) ,[Measures].[%Count])

But I don't get the right result because the date in abscissa creates a filter on the first date.

I tried also with %MDX function, but then I loose the context for the CURRENTMEMBER.

Hi!

There is an example in Samples which shows how to implement 'running total' measure: "Pareto Chart for Category" dashboard.

To calculate running total this pivot uses calculated measure with %Cell expression:

Hello, is there a way to reset all of the Sample Classes back to their "Installed State."? In other words, delete all the other classes I have put into the samples namespace and leave only those classes that were there when I installed the instance.?

Hello,

We are sometimes asked for examples of how to do 3rd party SQL database selects/updates/inserts/stored procedures from an Ensemble SQL Business Operation.

In the attached file there are 4 sample Ensemble Operations that demonstrate four different types of transactions with an external SQL DB:

1:  The "CheckExists" shows how to use an Operation to do a select statement to see if a given patient MRN exists in a DB
2:  The ExecSP Operation shows how to execute a stored procedure from a BO
3:  the Update Operation does an Update
4:  the Insert Operation does an Insert

Given the samples, one can co

Since we have a way to see 'Unanswered' questions now, there are a couple of things that jumped out at me.  Not sure if I am missing how to do these or if they need to be added to the future enhancements list:

1) It looks like a lot of people 'Comment' on a Question rather than providing an Answer.  This means that there are many questions listed as unanswered where the answer actually lies in a Comment (but noone has submitted a formal Answer).  Is there some way to tag a Comment as the Answer?

2) In many online forums a question isn't marked as Answered until the author of the question mar

Mirroring provides an admin capability to Stop Mirroring on this member, which causes a non-primary member to temporarily disconnect from the primary, stop dejournaling, etc.  While most system administrators may never need or use this function, some employ it for certain kinds of maintenance or other special cases.

The intent is that the administrator uses the Start Mirroring function when they wish the member to reconnect. However, today mirroring also implicitly restarts (reconnects) if the Caché instance restarts. Since this can be unintentional, we intend to change the Stop Mirroring funct

Hello!

I have a WebSocket application which spawns new process using JOB command.

Sometimes WebSocket connection can be terminated, and in the meantime I need to hold spawned process alive until it can be associated with the new WebSocket connection. (Do not suggest serializing process state here instead please)

Technically, in Caché WebSocket connection is represented by the class, which executes in its own process. This process is terminated when the connection is lost. In this case the JOBbed process does not terminates (thanks Edward), but it rely on $ZPARENT variable.

Is it possible to hold J
