I've noticed this before, that 'this' doesn't seem to get updated until fully inside the tag though it seems like it'd make more sense to have it apply in the tag that changes context. From the example:
<a:stories action="new" if="&can_create?" param="new-link">New Story</a> The context is being changed for use with the 'a' tag, though it doesn't affect the if statement, but does affect what is being linked. It's somewhat inconsistent there. What I ended up doing was something like: <do with="stories"><a action="new" if="&can_create?" param="new- link">New Story</a></do> (Not my actual code which I don't recall, was something with table- plus or a form) and that would work since the 'this' context has been set before entering the tag. I haven't looked at how tags actually get processed so this may be problematic for other reasons.
