Subject Re: t:selectManyPicklist does not assign POST data to bean property if nested in h:dataTable or ui:repeat
Date Thu, 12 Apr 2012 14:05:03 GMT
Hello again,

Replacing myfaces 2.1.2 api and impl with corresponding myfaces 2.1.7 jars
in Tomee 1.0.0 beta 2 does also not solve the problem.
Please help!

regards,
Max
