Hi,

I am using the Eclipse Galileo SR2 Modeling Tools Package which contains Xtext 0.7.2 under Mac OS X 10.6 and want to set up an Xtext project with Maven2.

The project structure is the standard Maven2 structure and there are no dependency problems. The grammar is also nothing special, it is a typical Xtext example.

Executing the MWE workflow works just fine but when I try to run the project as an Eclipse application I get the following error:

Quote:

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

I checked the constructor and the plugin.xml and they both are okay. Looks like the problem has something to do with the command "new MyDslUiModule()" in the "public void start" method of the "MyDslActivator" class. At least that's what I get from debugging.

Can somebody help me?
