Answer 1

Passing method expressions is not supported in tag files. Only since JSF 2.0 it's possible with so-called composite components.

What you can do is to separate the bean reference and the method name so that you can use the brace notation to invoke the method. I'm only not sure if that works out for an actionListener, you normally don't use that to invoke actions, but it should definitely work for an action.

E.g.

<my:tag ... bean="#{myBean}" actionMethod="preFillData" />

with inside tag.xhtml

<h:commandButton ... action="#{bean[actionMethod]}" />

Only if you happen to use JSF 2.0 on Facelets, then you can use <o:methodParam> to pass a method expression to a tag file. See also a.o. Dynamic ui include and commandButton.
