Problem with Seam + Trinidad.

[adamkoprowski]

Hello everybody,

I'm using EJB 2.0+JSP+myfaces+Trinidad in development for some time already but now I decided to make a switch to EJB3+Seam+Facelets+myfaces+Trinidad. I'm pretty impressed with what Seam has to offer but unfortunately now I'm having some issues with use of Trinidad that I didn't have before. Namely when I'm using <tr:tree> only the roots show up but no children. I'm using ChildPropertyTreeModel and in fact the getter for children is never called. I found out somebody having exactly the same problem: http://www.mail-archive.com/[e-mail]/msg01321.html but the post offers no solution.

I thought that maybe I messed up something with the configuration so I've taken the example seam-registrationtrinidad from seam's wiki page and added an option to display some trivial, fixed 3-nodes tree to it. Still, the same issue.

This is a big problem for me as it's holding me back with switching to Seam with development as I planned... Any help greatly appreciated!

Best wishes,
Adam Koprowski

I do recall having problems outjecting a treemodel from a seam component. I had it working using a managed bean (in faces-config.xml). Now I'm just using a facelets function[1] to convert it (not much use for you I know). I would suggest (a) creating the treemodel in a managed bean and injecting (via configuration in faces-config.xml) the list or (b) creating an extension of the TreeModel componentthat accepts a list and creates a treemodel from it.

Sorry for this being vague - but its been a while since I looked at this.

It looks to me like Trinidad is soon to release an milestone (m1), at that point I think it would be worth getting together a Seam/trinidad example similar to the icesfaces one.
