--------------------------------

             Summary: Automatic rendering of transitive dependencies
                 Key: RF-13128
                 URL: https://issues.jboss.org/browse/RF-13128
             Project: RichFaces
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: architectural, base functionality, core
    Affects Versions: 5.0.0.Alpha1
            Reporter: Juraj Húska
            Priority: Minor


Consider please following pseudo code for using {{r:dataScroller}}:

{code:xml}
<r:dataScroller id="topScroller" for="table" />
<r:dataTable>
 <r:column>Blah</r:column>
 <f:facet name="footer">
   <r:dataScroller render="topScroller"/>
 </f:facet>
</r:dataTable>
{code}

When the bottom scroller is changed, then the top scroller is as well, because the bottom one has {{render}} attribute set correctly.

It would be IMHO nice addition, if this had been done automatically. The {{r:dataTable}} may know which scroller is bound to it, and update it automatically.

[~lfryc] idea for general implementation:
??Support for it does not exist in JSF/RF right now. But it can be added. If you have {{render="A"}}, then also X would be rendered, where X are all transitive dependencies, which make the component. A component can have an interface, to which you can register those explicit targets. Datascroller would use such interface.??
