Yes, it's quite ridiculous :) But I needed to test...
My page should display all the objects (in fact the IDs) on the same page,
but on different tables :) !!
I think the loop with if components could be a good idea !! But I thought
there was a way to display only one element of the list...(with an index
parameter maybe).
The help from the community is great :) I always search the mailing-list
before posting, and I have to say that it already help me a lot !!
