Borja Santos commented on TRINIDAD-1523:
----------------------------------------
First of all.. I know that it was not a solution, and perhaps I did not use the
correct word when talking about it. Sorry for that and thank you for your quick
answer.
Not using the same id was one of the things that I was looking for, but since
the id property does not accept EL (security reasons) I'm not able to set
different id's..
There's another fact: the tr:iterator treats everything inside it as a unique
component.
e.g. in a concrete case I have three combos, and although when rendering they
have different id's (you know, blahbla:0:id, blahblah:1:id, and so on..), when
I try to get the source of a ValueChangeEvent, for example, it always returns
THE unique id, whether is the first combo or the second or..
So, in this scenario, I'm not able to build dynamic and dependent select boxes,
populating the 'child' combo when updating the selected value at the 'parent'.
Their values (the options of the combos) are lost somewhere when doing the PPR,
and when it tries to restore the index selected before, it throws the
IndexOutOfBoundsException..
I'll try to find a way of doing this.. but as I said before, thank you so much.
And of course, meanwhile, ideas are accepted.
Best regards,
Borja
