Hi,

Not sure if it’s the right place to post this topic.

I have made a recent upgrade of myeclipse ide, and found out that, I can’t edit struts-config.xml file with the graphical editor.
I can send you additional information if needed.

Message I get:

Unable to create this part due to an internal error. Reason for the failure: org.eclipse.draw2d.geometry.Dimension

plus the exception:

If you navigate to your <Eclipse dir>\plugins directory, do you have any GEF or EMF plugin directories? Did you happen to install VEP recently? (this is the problem you need to get rid of the EMF or GEF versions that VEP installed out of your <Eclipse dir>\plugins directory.)

[Michal Kuna]

I have both GEF and EMF plugins, don’t have VEP
gef 3.1.1
emf 2.1.0

everything worked fine until I upgraded myeclipse.

[Michal Kuna]

do you need any more info?

[Riyad Kalla]

No, I thought I was clear about what the problem was:

(this is the problem you need to get rid of the EMF or GEF versions that VEP installed out of your <Eclipse dir>\plugins directory.)

[Michal Kuna]

solved 🙂
