[jira] Commented: (MYFACES-148) datalist: problems with modelupdate and verbatim tag

Mike Youngstrom commented on MYFACES-148:
-----------------------------------------

I am experiencing the same problem.  Form components are not working as they should in dataList.  UIData components are supposed to rewrite the id for all components inside of it for each iteration.  DataList is not doing this.  If I repeat an inputText component in a data list all <input tags are given the same id.  Each iteration should have a different id derived from the iteration number so that decode, validation, and update can all decode, validation and update the correct values.

> I try to use the "datalist" with embedded inputText to change fields in my datamodel.
> After some debugging it turns out it is needet to put the inputText tag within an column tag
> e.g.
> <x:dataList>
> <h:colum>
> <h:inputText ...>
> </h:colum>
> <h:colum>
> <h:inputText ...>
> </h:colum>
> </x:dataList>
> I dont understand why this is needet as there is no need to render "columns" within an dataList.
> Which brings me to the next problem. If I try to embed verbatim tag ...
> <x:dataList>
> <f:verbatim><tr><td></f:verbatim>
> <h:colum>
> <h:inputText ...>
> <f:verbatim></td><td></f:verbatim>
> </h:colum>
> <h:colum>
> <h:inputText ...>
> <f:verbatim></td></tr></f:verbatim>
> </h:colum>
> </x:dataList>
> (It makes no difference how the tags are ordered only the classname in ClassCastException changes)
> ... I get the following exception:
> java.lang.ClassCastException: javax.faces.component.UIColumn
