New Project Wizard not shown [message #1705845]

Hi,

I wanted to add a new project wizard to my Xtext dsl. Therefore I added the following code to the .mwe2 file of the plugin:

              // provides a new project wizard
    		fragment = projectWizard.SimpleProjectWizardFragment {
			    generatorProjectName = "${projectName}.generator"
			    fileExtension = fileExtensions
			}

When regenerating this gave my a new namespace mydsl.wizard with MyDslProjectInfo.java and MyDSLNewProject.xpt

So far so good. Next I added the following code to MyDslUiModule.java

private AbstractUIPlugin plugin;  
	
	public MyDslUiModule(AbstractUIPlugin plugin) {
		super(plugin);
		this.plugin = plugin;
	}
	
	public void configureLanguageName(Binder binder) {  
	 binder.bind(String.class).annotatedWith(Names.named(Constants.LANGUAGE_NAME)).toInstance("com.somepath.mydsl");  
	}  
	  
	public void configureFileExtensions(Binder binder) {  
	 binder.bind(String.class).annotatedWith(Names.named(Constants.FILE_EXTENSIONS)).toInstance("mydsl");  
	}  
	  
	@Override  
	public void configure(Binder binder) {  
	 super.configure(binder);  
	 binder.bind(AbstractUIPlugin.class).toInstance(plugin);  
	 binder.bind(IDialogSettings.class).toInstance(plugin.getDialogSettings());  
	}  
	  
	  
	// contributed by org.eclipse.xtext.ui.generator.projectWizard.SimpleProjectWizardFragment  
	public Class<? extends org.eclipse.xtext.ui.wizard.IProjectCreator> bindIProjectCreator() {  
	 return MyDslProjectCreator.class;  
	}

However, the Wizard still does not show up. What am I missing out?

Thanks

Steffen

That was it! Thanks. The following was missing:

 <extension
         point="org.eclipse.ui.newWizards">
      <wizard
            category="org.eclipse.xtext.projectwiz"
            class="myNamespace.MyDslExecutableExtensionFactory:myNamespace.MyDslNewProjectWizard"
            id="myNamespace.MyDslNewProjectWizard"
            name="MyDsl Application"
            project="true">
      </wizard>
   </extension>

However, I now have the next problem. Well actually there are 2 of them.

1. No matter what workspace location I choose in the wizard, e.g. c:\test the project is always created in the current eclipse workspace, e.g. runtime workspace.

2. I want to use the name of the new project in the .xpt template. However the following code leads to the error "Attribute ProjectName not found in myNamespace::MyDsl::MyDslProjectInfo"

«DEFINE model FOR MyDslProjectInfo»
	«FILE "src/test.mydsl"-»
	Project Name: «this.ProjectName»
	«ENDFILE»
«ENDDEFINE»

Why does it ignore the Getter of DefaultProjectInfo class?

Thanks!

That was simple! It is working now (except for the bug with the location mentioned above) when I start it as runtime eclipse. When I export it as plugin (like I did it all the time before) the editor cannot start because:
