How can I use a list returned from persistence in a HTML dialog dataTable element?

Question

How can I use persistence to get results from query as a recordset, I can use directly in a dataTable-Element?

Accepted Answer

Instead of using a Recordset in the dataTable element in the html user dialog you can use the list returned from persistence directly:

<p:dataTable var="basis" value="#{data.basiswerte}">
  <p:column headerText="XYZ">
    <h:outputText value="#{basis.xyz}"/>
  </p:column>
  <p:column headerText="ABC">
    <h:outputText value="#{basis.abc}"/>
  </p:column>            
</p:dataTable>

It is important that you declare the attribute basiswerte of the data class with generic types e.g.

basiswerte: List<Basis>

so that jsf knows the class of the list entries. You can then access the fields of the Basis class directly in the dataTable. E.g. the field xyz with with #{basis.xyz}.
