I wonder if it's okay that String doesn't work when opposed to java.lang.String..
Finally I managed to get this running in my program, even for a controller case!
But I ran into the following crazy issue :
I am using a facelet-component with the same attribute name right above the composite component (seems to be some name clash):
<g:adjustableTable tablebean="#{HostsPageBean.tableBean}" value="#{HostsPageBean.hosts}">
</g:adjustableTable>
unless I comment those lines out the following
does not work
<h:panelGroup>
<gc:adjustableColumnHeader tablebean="#{HostsPageBean.tableBean}" header="Hostname" alwaysShown="#{true}" act="#{HostsPageBean.tableBean.hideByCheckboxes}"/>
</h:panelGroup>
I get:
#{compositeComponent.attrs.act}: java.lang.NullPointerException
javax.faces.FacesException: #{compositeComponent.attrs.act}: java.lang.NullPointerException
