Have a rich:datascroller + an a:commandlink inside rich:data

[bloodcell2]

Hello to all,

I have a rich:dataTable that displays stuff, it has a rich:datascroller inside its footer, and I also have an a:commandButton for adding an item to my display list (this is done through a rich:modalPanel)

I noticed a very user-friendly design would be to have the button also inside the table's footer (let's say: the button align to the footer's left, and the datascroller to its right).
But I can't get them both to display:

<f:facet name="footer">

 <rich:datascroller for="itemTable"
 id="sc"
 align="center"
 maxPages="100"
 renderIfSinglePage="false" />

 <a:commandButton value="Add an item"
 action="#{myBean.newItem}"
 oncomplete="Richfaces.showModalPanel('itemDetails');"
 reRender="itemDetails"
 ajaxSingle="true"
 immediate="true" />

</f:facet>

Also tried (cause I saw it somewhere) :

<f:facet name="footer">

 <rich:column>
 <rich:datascroller for="itemTable"
 id="sc"
 align="center"
 maxPages="100"
 renderIfSinglePage="false" />
 </rich:column>

 <rich:column breakBefore="true">
 <a:commandButton value="Add an item"
 action="#{myBean.newItem}"
 oncomplete="Richfaces.showModalPanel('itemDetails');"
 reRender="itemDetails"
 ajaxSingle="true"
 immediate="true" />
 </rich:column>
</f:facet>

... Which yielded wierd results (the scroller isn't displayed and the button is not inside the footer).

Do you guys have any idea how to accomplish this ?
(seems like a valid GUI design way)

Thanks!

I just realized that <f:facet> probably accepts only one UI component nested inside it, and that's why we should wrap the a:commandButton and rich:datascroller together inside an h:panelGroup or, as in my case, an h:panelGrid.
(I then realized this was a dumb ass question, but if I already asked it - might as well answer it) :

<f:facet name="footer">

 <h:panelGrid columns="2">

 <rich:datascroller for="itemTable"
 id="sc"
 align="center"
 maxPages="100"
 renderIfSinglePage="false" />

 <a:commandButton value="Add an item"
 action="#{myBean.newItem}"
 oncomplete="Richfaces.showModalPanel('itemDetails');"
 reRender="itemDetails"
 ajaxSingle="true"
 immediate="true" />

 </h:panelGrid>

</f:facet>
