Hello!

In my project a new temporary editor-file is built by clicking on a button. This file ends everytime on ".calculation". Furthermore an anomaly of this file is that it does not belong to a project.
Now I want to add my xtext-nature to this file.
I've tried it with tis code:
public class NatureAddingEditorCallback extends AbstractDirtyStateAwareEditorCallback {
	
	@Inject
	private ToggleXtextNatureAction toggleNature;

	@Override
	public void afterCreatePartControl(XtextEditor editor) {
		super.afterCreatePartControl(editor);
		IResource resource = editor.getResource();
		if (resource!=null && resource.getName().contains(".calculation")){		
                        toggleNature.toggleNature(resource.getProject());
		}
	}
}


But this method is not called.
Can you help me, please?

Nice regards
Jule

How did you bind the callback?

I've bound it this way:
public class CalculationUiModule extends de.dlr.virsat.calculation.model.ui.AbstractCalculationUiModule {
	public CalculationUiModule(AbstractUIPlugin plugin) {
		super(plugin);
	}
	
	 public Class<? extends org.eclipse.xtext.ui.editor.IXtextEditorCallback> bindIXtextEditorCallback() {

		// return your version of the NatureAddingEditorCallback
		return NatureAddingEditorCallback.class;
		}
}

Maybe it is because I don't have a project to add the xtext-nature on?
Is it possible to add the xtext-nature only to a file without project?

Hmm looks good so far - recheck this adding the override annotation

No you need an .mydsl file contained in a project
