Not sure this helps... In my early stumbling around
Facelets/Woodstock, I discovered
Facelets did not like MethodExpressions very much (still expected string
actions).
This is basically why Actions still work. When we investigated this a
bit, it turned
out that JSP was providing a conversion method to wrap the
ActionExpression return,
but Facelets was not. Not sure where the fault lies, or rather
anything further has
happened to address this, but two cents worth....
