Another benefit of doing it the way Tim suggests is that the links will be visible in diagrams produced by tools such as Umlanji and Caché Class Explorer.

I think you stand a better chance of getting responses to this if you move it to the HealthShare group and tag it with a HealthShare-related tag. The "Developer Community" tag and the "Developer Community Feedback" group are intended for posts/questions about the DC forum itself, not the InterSystems products. Posts tagged/classified like that don't appear on people's general new feed, AFAIK.

An interesting article, but I'm puzzled by your use of the term "I11n". I'm familiar with "I18n" as an abbreviation for Internationalization (because there are 18 letters between the "I" and the "n". Likewise, I understand "L10n" as standing for Localization. Some Googling suggests that "I11n" is short for Introspection. Or have I missed something?

A very interesting article Alexey.

One minor observation: you wrote "ECP, or distributed cache protocol, ...". It may be worth saying that ECP stands for Enterprise Cache Protocol (AFAIK). Before ECP InterSystems had a similar thing called DCP, which stood for Distributed Cache Protocol.

Another option is to use Serenji

Does your where clause need a colon in front of pVariable ?

where COLUMNC = :pVariable

If that doesn't fix it, I suggest you first check whether the problem is caused by the &sql(...) or by the way your web page is calling your server-side method.

Remove all your code between the opening &sql( and the closing ) - incidentally, I assume you have a closing ) even though it didn't show in your post.

Make your method end with QUIT pVariable instead of returning tempVariable1.

Do you still get a Javascript error?

For a class definition you can get the timestamp of last change from the TimeChanged property of the %Dictionary.ClassDefinition instance for the class.

For a routine, the TimeStamp property of its %Library.Routine instance is what you want.

But AFAIK the associated username isn't recorded automatically. You could use the server-side source control class interface to record this kind of thing, but it relies on whatever is making the change actually collaborating with that interface.

Do you use any form of source control?

Please tell us what version of Cache you are currently using.

Please explain what you mean by "Class(set) Operators".

Great article Dmitry. I think there's a minor typo under the dump of the big string block. You wrote:

Unfortunately, this block is shown unencrypted.

I think you mean "encrypted". Or perhaps better to say "encoded", and to refer to "decoding" in the subsequent sentence instead of "decryption".

Can you tell us why you need an alternative?

from Cache Studio, when I examine the output of the class given above, I get the error message:

...

Please tell us exactly how you are using the class from within Studio.

set %session.EndSession=1

See the class documentation for the %CSP.Session class, of which %session is an instance.
