Thanks,
I suspected something like that, but this is some of my first attempts at using the ajax stuff so I wanted to make sure it was me misusing the components
Speaking about good practices, I was setting up some things some actions in my setters for the "item" binding, which screwed me a bit because it getting called for each item in the list AND one more time with null (as its cleaning up the repetition I suppose) 8-) 8-) 8-)
Morale: don't take shortcuts !
Thanks you very much...
