Populating Datums with Tokens

Hello,
I have a datum that needs to be passed to an external, used for a Rest call. I'm specifically trying to get the user id of the user that's logged in.
I'm trying to use the $CONTEXT{userSession.user.id} token in my datum, but it's not working.
Here is what I'm trying to do:
[html]

http://localhost:8080/test/getAlerts.xml?userId=$CONTEXT{userSession.user.id}

test.cms.contoller.TestRestController
handleRequest

[/html]

Page tokens are evaluated during the rendering which is after the external call. You need to write code in your TestRestController to extract the user data from the RequestContext, it has a UserProfile attached with everything you need.

Thanks Alex!
I'm assuming that, @ rendering time, LS does a find/replace kind of logic on the XSL skin before the final rendering to replace the tokens.

Do you know if there is any code/call that I can leverage that's already written in the LS runtime library that can do this replacement for me?

The reason why I'm trying to reuse the token approach is that I'll have many restful calls I'll have to use and may need URL replacement as well.

Thanks!

The output is cached in a parsed state and everything is streamed out as needed. Find/Replace would be way too ineffiecient under load.

You can write your own page tokens and even override the existing ones.

I found the following method that seems to be doing what I was looking for:

String URL = context.getParameterString(this.PARAMETER_REST_URL);
URL = PageTokenFactory.renderUsingDefaultFactory(URL, context);

By using this line, I can replace tokens added to the datums. So my Datum looks like:

[html]
http://localhost:8080/test/getAlerts.xml?userId=$CONTEXT{session.userProfile.id}
