h:dataTable Beginner's question

[Dipl.-Ing. Torsten Liermann]

Hi,

A Beginner's question to h:dataTable

I have a table for each row another
Combo box must be generated. The contents surrender from the current row object

Unfortunately, the expression Language does not support the following syntax:

<h:selectOneMenu styleClass="blue" value="currentVersion">
  <f:selectItems value="#{backedBean.version(rowObject}"/>
</h:selectOneMenu>


Is there a callback into the backing bean which is called for each row?
Or how is the recommended way without touch the domain object?

Thanks
Torsten
