I have found a strange behaviour with a4j:status
<a4j:status id="status" layout="block">
<f:facet name="start">
<img style="float:right" src="${path.staticUrl}images/busy.gif" />
</f:facet>
<f:facet name="stop">
</f:facet>
</a4j:status>
Apparently the tag isn't accepted and the resulting html code does not include my tag.
Is this actually intended behaviour, and if so how can I do this otherwise?
