Hi all,

I’m using MyEclipse 4.0.2 GA on Windows XP Professional. I’m encountering the following problems when trying to work with Spring.

1) Under Eclipse Preferences, MyEclipse->Project Capabilities, I get an error when I click on “Spring”. The error message is The currently displayed page contains invalid values.

2) If I try and add Spring capabilities to a Web Project, I get the error An error has occurred. Please see error log for more details.
Here’s the details from the error log:

Message: Problems occurred when invoking code from plug-in: “org.eclipse.jface”.

Am I missing something with my installation, or could this be a bug somewhere?

Thanks!

Hmm, can you please paste the result of the MyEclipse > About > Configuration dialog here, also try and restart using the -clean command line argument and see if that helps.

Try create a new web project and adding spring caps to it, does it work?

[everbright]

Hi rkalla,

Have tried using the -clean option, but that didn’t work either. Same observations as before.

What do you mean by the result of MyEclipse->About->Configuration? How do I get to this? Apologies, a bit new to this.

Thanks for your help with this!

Hi rkalla,

I’ve tried to un-install and re-install MyEclipse, and still got the same pop-up error as before. However this time round, I got a different error message in the Eclipse error logs:

Does this help us to find out what’s wrong?

[everbright]

The strange thing is that when I tried installing it on another machine, the functionality works fine?!

I’ve got no other plugins installed on the problem so there should not be any conflicts anywhere, else the error logs would have captured it, but the log is blank when I start up Eclipse with MyEclipse.

Hi,

Finally figured out what’s wrong… sort of. Seems like I have a slightly corrupted Eclipse workspace. Tried switching to a entirely new workspace, and re-configuring all my Eclipse and MyEclipse prefences and the Spring functionality are working fine now!

Sorry for the false alarm 🙁
