Description fahua jin CLA 2011-11-02 02:49:52 EDT 
Build Identifier: 0.7.0.v201111012101

There're two FormField part definitions in EDT, one is org.eclipse.edt.mof.egl.FormField, and another is org.eclipse.edt.rui.mvc.FormField. In the attached handler, it should import the formfield defined in the mvc. But I incautiously import the formfield in the mof package, it gives me very confuse error message.

1) Please download & import the attached H1.egl to the workspace.
2) No error decorator in the project icon, while you can see two errors in the problems view.

Created attachment 206309 [details]
The sample EGL file.
Comment 2 Matt Heitz CLA 2011-11-02 09:46:45 EDT 
This bug belongs on the IDE Core component.  EDT Builds is for problems that happen when compiling, downloading, or installing EDT.
Comment 3 Brian Svihovec CLA 2011-11-02 16:02:01 EDT 
I think we should start the investigation the Mof Model, since the exception is happening in org.eclipse.edt.compiler.internal.egl2mof.Egl2MofBase.setUpEglTypedElement(Egl2MofBase.java:1856)

NOTE: This defect is slightly related to Bug 362628.
Comment 4 fahua jin CLA 2011-11-03 03:39:56 EDT 
Upgrade the defect severity to major because it always happens when using the MVC and organize import function.
Comment 5 Paul Harmon CLA 2011-11-03 10:29:34 EDT 
I have updated Egl2MofBase to fix the class cast exception.
