Page break - Zen Report

I have two tables in a row in my report, but if the first table gets too big to the point that tables 1 and 2 don't fit on the page, the page breaks.


The problem is that the page break is happening in the middle of table 2 and I wanted the page to break and leave table 2 on the second page.


No table grows to the point of occupying more than one page alone.


Any tips on how to guarantee this?

Remembering that the reports were made using Zen Report.

Hi

I have been experimenting with the creation of a set of REST services for an app. The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return. However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)

I have two pages and I am using the push and pop to go and back navigation. When I click the button forward and back in the browser, I can't navigate more between pages.

The following code:

Page 1 - onSelect Method:
var obj = {idExame: VALID, objUsu: ObjUsu};
zenPage.gotoArea ('itemexames', key, key, false);
view.pushDocument (key, obj, key, obj);


Page 2 - onSelectMethod, back:

var documentKey = "PacienteExamesinitial";
var layoutKey = "PacienteExamesinitial";
var area = "pacienteexames";

I want to limit the length of the value of a textarea in Zen. In HTML the textarea element has a 'maxlength' attribute, but the Zen component doesn't have an equivalent property. Is there any way to add a maximum length in Zen short of creating my own custom component?

I'm using FOP 1.1 for ZEN reports and would like to install fonts within the Windows/Fonts directory.

I added the xml tags in fop.xconf but so far I have been unable to get the correct font.

<renderers>
<renderer mime="application/pdf">

<fonts>
<directory>c:\windows\fonts</directory>
<!-- automatically detect operating system installed fonts -->
<auto-detect/>
</fonts>

</renderer>

</renderers>

Any advice would be appreciated.

We need to generate a PDF file from an HL7 message as it passes through an Ensemble production. Looking for examples, tutorials, documentation aligned to our scenario.

We are currently using Ensemble (so can't use InterSystems Reports at the moment). Thinking Zen reports...

We can get from HL7 to XML OK, following Introduction to InterSystems Health Connect - YouTube (see c.1:11:00-1:13:00)

ZEN Mojo onEvent() callback

Hi - Trapping onselect and onchange events that occur on layout objects seems to work fine, however, according to the documentation, I should also be able to use onevent, which is defined as follows:

onevent: Defines how the page behaves when another type of event occurs within a documentView (an event other than select or change).

and has the method signature:

Hi,

I need to set the label of a custom setting in the portal instead of the name of the associated property, eg.:

Class SomeClass Extends (Ens.BusinessService, %ZEN.Portal.ContextSearch)

{

Property ABadPropertyNameToChange As %Boolean;

Parameter SETTINGS = "ABadPropertyNameToChange:CustomSettingsSection"
}

will result in this in the portal

-------------------------------
CustomSettingsSection

ABadPropertyNameToChange

I created a new class DSW.Addons.htmlViewer:

Class DSW.Addons.htmlViewer Extends %DeepSee.Component.Portlet.abstractPortlet
{

Property Data As %String;

ClassMethod %OnGetPortletSettings(Output pInfo As %List, ByRef pSettings) As %Status
{
    Kill pInfo
    Set pInfo(1) = $lb("Data", , , "Data", "Data setting")
    Quit $$$OK
}
}

It's a ZEN component and DeepSee portlet. It's immediately available in the namespace I created it in. DSW package is mapped to %ALL and to Samples, but if I try to create a widget with this portlet I get ZEN class not found error.

If a user simply closes a tab (running a web application), is there any good way to ensure that the license is released AND the login cookie is destroyed?

I found that if the tab is simply closed without first logging out of the application, then 1) the license hangs around forever, and 2) if the user then opens a tab, he is already logged in.

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

I have a dataListBox in ZEN which has an OnDrawItem method associated with it. The DrawItem method never seems to be called and I cannot see why. I am using IE11. Can anyone suggest a reason? The attached code runs in a namespace called CODE and can be run using view webpage on the TheLabsApp.BioAnal class. Please note that the data is in a global called ^%ANAL that resides in %SYS.

Hi,

I am working on a DataGrid based upon ZenTest.Datagrid.cls

I want to save data after changes on a row.

The existing samples do not explain how to save changes on data in a grid.

I have tried something like zen(‘json’).save

Does anybody has some sample code?

Telnet in a ZEN page

I need to find a solution for a client that has ZEN based application. Certain parts of this application remained Terminal based for which a unsigned Java applet was used to embedded this within the application. The control is old and requires an old version of Java which IT folks are not happy about.

I am looking for a replacement that will allow a terminal, either telnet or directly use cTerm, window to be embedded within a web application, specifically ZEN, based on Cache. Any suggestions or success stories would be welcome.
