[jsr-314-open] <h:dataTable> binding vs. ui:repeat

[Lincoln Baxter, III]

First, please let me know if there is a better place to ask JSF Dev
related questions.

Question for you all: I could use some help.

I'm testing my listener changes with the new EL2 (and also Seam EL just
in case)-- I wanted to make sure that parameters can be passed through
the EL action MethodExpression.

It seems as though parameters work fine in general, but if the parameter
is cc.attrs.* --- EL resolves the param values to null.

So:
    #{myObject} -- works if in scope, as it should
    #{cc.attrs.myObject} -- null, even though it's passed in from
#{myObject} as an attribute.

UICommand components seem to have no trouble with resolving cc.attrs.*,
though.

Any thoughts? I've attached the modified source files in case anyone
wants to take a look. I'm not sure if this is a larger problem, or if
I've just missed something.

Thanks,
Lincoln
