Description Darius Jockel

The diagram project shows an error:
org.eclipse.gmf.runtime.diagram.ui.editpolicies.LayoutEditPolicy cannot be resolved to a type	SimpleTypeEditPart.java	/org.eclipse.xtext.example.gmf.diagram/src/org/eclipse/xtext/example/gmf/diagram/edit/parts	line 72	Java Problem

Replace by:
 org.eclipse.gef.editpolicies.LayoutEditPolicy
solves the problem and makes the example work.

Not on my machine. Everything compiles fine as is. The code is working withGMF 2.3 RC2, which was kind of a hassle to install.

Have you installed GMF Tooling, GMF Runtime and GMF Notation completely, i.e. with all dependencies? Did you regenerate the gmfgen model or the diagram code?

AFAIR, org.eclipse.gmf.runtime.diagram.ui.editpolicies.LayoutEditPolicy has been around since the beginnings of GMF (and still is), so it looks like a missing dependency. The GEF version is a superclass lacking some essential functionality, so this should not be a valid replacement.

Hello,

I use Galileo Modeling RC2. GMF is allready installed in this distribution.
Generating the diagram project 
(models project model -> Entities.gmfgen -> Contextmenu -> 'Generate diagram code)
solves the problem.

This happens when you try to run code generated with GMF 2.3 in a GMF 2.2 environment.

To get rid of the error you have to regenerate the diagram code by choosing "Generate diagram code" from the context menu of the gmfgen model. 

I added a section on this in the docs.

Closing this issue.

Closing bug which were set to RESOLVED before Eclipse Neon.0.
