Primefaces datatable with inner ui:repeat

Question

I am currently using PrimeFaces and I am quite satisfied with it. But now I am stuck.

I am displaying a p:DataTable with my entities. My entities also have child entities which I also want to display. Each child entity of my parent entity should result in a new row with the data of the parent entity and the data of the child entity.

So something like this:

Parent1.A | Parent1.B | Parent1.C | Child1.A | Child1.B
Parent1.A | Parent1.B | Parent1.C | Child2.A | Child2.B
Parent1.A | Parent1.B | Parent1.C | Child3.A | Child3.B
[...]

So I tried something like this, but this didn't work..

<p:dataTable value="#{myBean.entities}" var="entity">
    <ui:repeat value="#{entity.children}" var="child">
        /* dataTable columns ... */
    </ui:repeat>
</p:dataTable>

This code won't show anything unfortunately.. without the inner repeat, the dataTable is displayed (of course without the children entity data..). How can I achieve this way of data display?

Thanks for your help in advance!

Best regards!

Use a DataTable - SubTable as in the official sample here
