rich dataTable can not use iterate variable for a nested loop

Question

I\'m building a rich datatable with a dynamic amount of columns. It seems to me, that it is not a big thing, but I\'m trying to get an answer since hours. The issue is when

Answer 1

I think <ui:repeat> doesn't work because <rich:column> is not what ui:repeat is designed to deal with (e.g. a <li> or something like that), <a4j:repeat> which you should be using instead won't work there either (and that has something to do with the way the table is built).

<c:forEach> will work, with a little hack:

<c:forEach var="index" begin="0" end="#{reportingModel.columns - 1}">
    <rich:column style="text-align:right;">
        <h:outputText value="#{reportingDoiPoolRow.amountOfDois.get(index)}" />
    </rich:column>
</c:forEach>

<c:forEach> does not have access to the attributes from <rich:dataTable> (well, it has access to rowKeyVar but that will be always 1) so you'll have to ask the bean directly for the column size but the pieces rendered by <c:forEach> will have access to the var.
