2010-06-15 04:57:09 EDT

What steps will reproduce the problem?
1. create a schema file (.xsd)

Looks like some class is missing in the plugin package

Comment 1 Valentin Baciu

Luciana, is this problem consistent or intermittent?

Ed, any chance you've seen similar XSD EMF model stack traces?

Comment 2 Ed Merks

2010-07-20 17:09:53 EDT

It's hard to imagine this method could fail.

  protected EClass eStaticClass()
  {
    return XSDPackage.Literals.XSD_SCHEMA;
  }

It seems highly likely there would be other errors earlier in the log that would be more informative.

I have tried to re-produce the error today but it did not happen again. Since I reported the bug I switched to XML Editor and cannot tell you at which point this problem disappeared. I have in the mean time done several modification in my eclipse environment with different plugins.

What I can tell you is that now it works nicely again. 
My eclipse version is now:
  Eclipse IDE for Java EE Developers	1.2.2.20100217-2310	epp.package.jee

Thank you. I'll resolve as "works for me".
