Thanks Lincoln. I haven't had time to debug this, but I have a

We expect "cc" to resolve to the containing composite component (ie.
to the <socialpm:taskBlock> component). I wouldn't be surprised if
what is actually happening is that "cc" is being resolved to the
<a:editText> composite component instead.
Yep, that's what is happening.
One reason why I suspect this might be happening is that I know that
Ryan has investigated/resolved similar problems not too long ago.
The problem we
resolved was the passing of #{cc.attrs} attributes
between nested composite components.
For this case, the spec recommends using cc.parent.attrs.story and
cc.parent.attrs.task, where parent resolves
to the nearest composite component parent of the current composite
component.
Another reason why I am suspicious about this is because we have
faced
similar issues in our own (ADF Faces) declarative component solution.
This stuff can get tricky. :-)
Hey Ryan -
Does this problem look familiar? Any thoughts on this?
