DataList component causes duplicate id inside repeat

jzuccaro Feb 8, 2009 2:10 PM

If I place a DataList component inside an a4j:repeat the pages throws a Duplicate id exception after the second refresh, even if the component has rendered=false.

I have explicit ids for all components, and I narrowed the problem to the Datalist, if I remove it from the page all works.

I have also tried to replace DataList with another repeat and ul and li tags to no avail.

Is this expected behavior?

Hi,

I see no problems running the code, so I think session binding for a4j:repeat is the reason.

Hi nbelaevski!

You are right, indexInformacion (where I have the repeat component) was registered with session scope, Changing it to request solved my problem

Thank you!
