NoClassDefFoundError occurred when editing Grails Controller Class

[grspring]

Hello, I use nightly STS Grails Support (2.3.1.201002150800-CI-R4660-B124).
I have installed STS according to this file (http://dist.springsource.com/release....0.RELEASE.pdf)

When I have created Grails project, a controller class of grails, and focused on editor, a dialog message has poped up.
the message says NoClassDefFoundError occurred ...

What's the error cause?

My System Environment is

• WindowsXP
• JDK 1.6.0_18
• Grails 1.2.1

The Error Message is here.

grspring,

thanks for raising this. This has been fixed in trunk and the fix will be included in tomorrow's nightly snapshot.

Thanks, Christian

[grspring]

Thank you for updating STS!
I have confirmed that I can edit the Grails Controller Class nomally by new STS.
