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

["Alex Mayer (JIRA)" <in...@incubator.apache.org>]

     [ http://issues.apache.org/jira/browse/MYFACES-148?page=comments#action_61730 ]
     
Alex Mayer commented on MYFACES-148:
------------------------------------

i tried to embed inputText in dataList too, like that:

<x:dataList value="#{user.currentApp.fields}" var="a" layout="unorderedList">                
   <h:outputLabel value="#{a.label}" />
   <h:inputText maxlength="#{a.maxlength}" value="#{a.currentValue}" />
</x:dataList>

when i then tried to read the field-values, i always got "null" which means that no value was set at all. 
i looked at the created html-code of the jsp-page and saw that the name-attribute for every <h:inputText>-Field generated was the same, e.g.: <input type="text" name="_id0:_id2:0:_id6" maxlength="8" />

for a <h:dataTable>-tag the name-attribute generated is always different, counted up like this: name="_id0:_id2:0:_id6" name="_id0:_id2:1:_id6" name="_id0:_id2:2:_id6"

maybe there is a problem in the namingContainer for dataList?

> 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

> <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.

> <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)
