a:support reRender does not work

ajax4jsf-1.1.1

Are there any known situations when a:support reRender option does not work? Does it matter in which element a:support is nested? I have a:support element inside a h:checkbox like following:

<h:selectBooleanCheckbox id="categoryCheckbox" value="#{item.selected}" styleClass="checkbox">
 <a:support event="onclick" actionListener="#{item.setSelected}" RequestDelay="3" immediate="true" reRender="treeRegion"/>
</h:selectBooleanCheckbox>

It does not seem to reRender the treeRegion (a:region)?

a:region is NOT an output component. You cannot point to it.
Actually, you can, but without any success.
