Russ,
Is there a feature you needed in Spring IDE that isn’t in MyEclipse yet?
If you need to turn off MyEclipse’s SPring support, you can go to Window > Prefs > General > Capabilities, hit Advanced, and go under MyEclipse Standard and uncheck the “Spring Framework Support” and hit OK.
Alternatively, one of our developers says you should be able to install SpringIDE 2.0 even without turning off the existing functionality in MyEclipse… although I’m concerned with menu-collisions or duplicate entries which is why I’m suggesting you do it.
Your call.
