Hi Baptiste,
I would like to have a dynamic suggestion list, e.g. the content of
the list would be recovered from a database when the other fields of
the CForms are changed.
Is it possible for a widget to fire an event to the suggestion list
and then changing the content of the list ?
I just want to know if this is would take too much time for such a
feature.
First please have a look at:
http://cocoon.apache.org/2.1/userdocs/widgetconcepts/selectionlists.html
According to the book "Cocoon 2 und Tomcat" from Stephan Niedermeier
there is another way via a Java class extending
org.apache.cocoon.forms.datatype.AbstractJavaSelectionList.
Anyway, updating the selection list dynamically is not the problem. The
tricky part is getting access to the underlying model.
Any elegant ideas out there? (I need it, too :-)

Hi Florian,
Thanks for your answer !
About updating the list, do you mean using something like
<fd:selection-list src="cocoon:/mychoices.xml" dynamic="true"/> ?
Or is it about changing the <map:match pattern="_cocoon/forms/suggest">
part ?
I'm quite interested about this, as the only information I've found is
Christofer Dutz' idea
(http://marc.info/?l=xml-cocoon-users&m=115649772124493&q=p3).
You are certainly right about the tricky part, I am querying my database
with java objects using Hibernate. Sessions are managed by the
flowscript and a servlet filter so I don't see any solution here :-(
