Dynamic suggestion list
Hello,
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.
Using fd:union looks complicated as I would have about 32 different cases !
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.
Any advice would be appreciated :)

Never mind - just help others when you have upgraded to a cocoon Jedi* :-)

Yesno. I think the data delivered by cocoon:/mychoices.xml could be dynamic.

:-?

Thanks for the link. Will have a look at it tomorrow.

Yes, that might look difficult, too. But what I'm thinking of is how to
invoke the "form on hold" (via showForm) to redisplay it in the browser.
I have problems to call the form from withing the
fd:on-value-changed/fd:javascript part in the form definition file. :-?
Good night,
Florian

Hi Christofer,
Thanks for your feedback, but at the moment I am not working on this. I
may mail you if I need some informations on your solution ;)

Hi Baptiste,
Just saw that the main part of my solution was a custom generator I
wrote, that simply gets a form instance curently shown and outputs it's
current content in xml form. I use this to transform it to any
individual suggestion-list output.
Unfortunately you have to tweak the dojo code a litte to make the
suggestion lists "onvaluechangeable" ... I will gladly share my code.

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 :-(

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 Baptiste,
You may find what you are looking for by looking at the "Cocoon suggests" sample, that uses Ajax to dynamically updates the selection list, depending
on what is being entered.
