Isn’t basic deferred EL support (the # variation) already present in MyEclipse?
What I personally would like to see is a “navigate to declaration” option for EL. This should be such a small thing. The editor obviously already knows the exact type and location of the element in the EL expression (otherwise it wouldn’t be able to offer context assist). So, the only thing left for the editor developers would be to couple that information to a clickable hyperlink that appears when you press and hold the ctrl key.
This would give me a HUGE improvement in productivity when working with JSF pages. Currently our team has resorted to adopting naming conventions for managed beans, just to be able to find the corresponding class back. This is sometimes a rather awkward naming scheme, and it still doesn’t always allow us to find the class in question quickly.
