Hi,

I am trying out current SVN version of the taipan example.
The environment is
eclipse.buildId=I20090611-1540
java.version=1.6.0_16
GMF 2.2.0 20090114

When I want to generate the editor out of taipan_rcp.gmfgen (rev 1.41) I get
an "Unhandled event loop exception" in the error log, including the
following details. Does anybody know what the cause could be?

Thanks in advance,

Axel

Hi,

does anybody have an idea why the notation ecore model could not be loaded?
I pasted the exception details at the bottom of this mail.

Looking into my plugin folder the ecore file is there, included in the
corresponding plugin jar file.

Regards,

Axel

Hello Axel,

I just tried generating code from taipan_rcp.gmfgen downloaded from CVS and
it was possible..
Exception you pasted here is very strange.. It looks like org.eclipse.gmf.runtime.notation
was not properly loaded. Areyou sure you have correct GMF installation?

Hi Alex,

did some further testing: both problems do only occur if I have current CVS
version of org.eclipse.gmf.codegen as open project (I am used to do this for
comparing new template amendments). If I close this project and restart
Eclipse, the installed plugin version is used and code generation goes fine.

Inside the org.eclipse.gmf.codegen project loading the notation metamodel
fails in BuildUtils.qvto and Utils.qvto concretely.

Regards,

Axel Guckelsberger
