regain focus

[dev.pma]

I'm trying to set the focus on a <h:inputText id="myId" /> component by setting the focus attribute in the adhering <a4j:form focus="myId" /> as described in the reference. No success.
I also tried to make use of the <a4j:support focus="myId" /> tag. No success.
What do I miss? Thanks in advance!
