rich:columns should allow rich:column to be nested

[hanafey]

rich:columns does not seem to allow you to set different styles on the columns in a natural and flexible way.

For example, rich:column (singular, not plural!) has a style attribue which is applied to the td element that contains the value component, but the content of rich:columns (plural!) does not take a rich:column child, and so there is no place for the style attribute. A style on the value component of course is not applied to the td element. (In reality, a rich:column inside of a rich:columns produces a nested td, which is not too useful).

If rich:columns properly supported a rich:column child, then all of the attributes of rich:column would be available, which would allow this attributes to be set based on the column iteration variable.

For example:

<rich:columns value="#{RestrictionContainer.leadTable.columns}" var="col">
 <rich:column style="#{col.style}">
 <f:facet name="header">
 <h:outputText value="#{col.header}"/>
 </f:facet>
 <h:outputText value="#{x[col.property]}" converter="#{col.converter}" escape="#{col.escape}"/>
 </rich:column>
 </rich:columns>

Hi,

You can use c:forEach instead of rich:columns then.

And checking tlddoc I see both style and styleClass attributes on columns tag. So just try to add style="#{col.style}" to the columns

Thanks for the replies.

I did see style and styleClass on rich:columns, but just assumed that these values could not reference the column iteration variable, but testing shows that they can, so this provides exactly what was needed.

Intellij agrees with me this is a bit counter intuitive because it flags the use of the iteration variable in a sibling attribute as an error...
