Had this after the last upgrade whenever trying to open any form of jsp editer/page designer/even the "classic" html editor:

An error has occurred when initializing the input for the the editor's source page.

Last time a reboot took care of it, but not this time.

Eclipse:

Version: 3.1.0
Build id: I20050513-1415

Latest 4.0.0 GA of MyEclipse.

I am on the Mac OSX 10.4.2

Any help?

THanks, Ed

This is not the final GA version of Eclipse 3.1, this is a requirement for MyEclipse 4.0M3 and 4.0 GA (which is why you likely saw the problem last time as well). We suggest a fresh install of Eclipse 3.1 SDK and reinstall MyEclipse, be sure to add -clean to your command line arg and point at your existing workspace, you should be back in action.

Ok, that is what i did do and all is well now...

Thanks!
