> value="#{MyController1.myList}" ...>
> <t:commandButton id="batchSelectCmd" forceId="true"
> immediate="true"
> action="#{MyController12.search}"

> disabled="#{empty batch.attributes['reviewState'][0]}"
> ... >
> <t:updateActionListener property="#{requestScope['selectedBatch']}" value="#{batch.value}"/>
> </t:commandButton>
> </t:dataList>
> Commands are working with the 1.1 compliant libs.
> Commands are working without t:updateActionListener.
> A similar issue is MYFACES-1819 "h:selectManyCheckbox with value="#{bean.map['somekey']}" fails"
> A workaround is to replace updateActionListener by setPropertyActionListener (Thanks to Mike Kienenberger).
> Copied from the corresponding email thread on the dev list from Leonardo Uribe:
> "In few words the problem is that in EL, expressions like "#{bean.map['somekey']}" returns null when getType() is called. Note this does not happens in jsf 1.1, but on jsf 1.2.
> Checking the code of f:setPropertyActionListener, it just do a simple call like this:
> target.setValue(ectx, value.getValue(ectx));
> But t:updateActionListener has an additional converter property, so it try to use the converter before call setValue."
>
> Discussion in user list.
