Hi,
I have a document where the user set the name of a document in a textfield
to create a new document as described in the FAQ tutorial.
How is it possible to set a property of the document's object
programmatically? In my case I have a property "id_project" of my class
"project". I want to set the value (an automatically generated id value) of
this property in the new document right after creating it, without user
interaction. It should save the id value with the other values the user
defines before saving the document for the first time.
Thanks a lot!

Hi,
add DocumentCreatedListener to the List from getEvents() in Example
http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial
and use
@Override
public void onEvent(Event event, Object source, Object data) {
XWikiDocument doc = (XWikiDocument) source;
XWikiContext context = (XWikiContext) data;
if (event instanceof DocumentCreatedEvent) {
// Do what you need here ;-)
}
}

Thank you very much, Matthias - but I cannot figure out how to use it.
I have added the following code to my Class Sheet of the project class to
examine the functionality.
What I try is to print the variable content on save and update of a project
document, but there is no output visible.
Could you please give me a hint? Thanks in advance!

New subject: [xwiki-devs] How to set a properties value on a newly created document
Fixed value can be set by document template which is provided to create
in new Class creation wizard. (Open template document in object editor
mode and enter necessary values).
Dynamic value can be set using document sheet
http://extensions.xwiki.org/xwiki/bin/view/Extension/Sheet+Module
with following Velocity code:
{{velocity}}
#if($doc.isNew())
#set($obj=$doc.getObject('Space.YourObjectClass'))
$obj.set('property','value))
#end
