I use rich:extDT:
Is that normal:
<rich:column label="LABEL"> <f:facet name="header"> <h:outputText value="Label"/> </f:facet> <h:outputText value =".."/> </rich:column>
<!--this does not show me the header-label--> <rich:column label="LABEL"> <h:outputText value =".."/> </rich:column>
label attribute used for different use.. column in built-in dropDownMenu represented for example using this label.
