I programmatically added sub-element to an existing model.
I also added dynamically an entry in the palette so that when I click on it I will create the element but I don't need to create the view
The elment is created successfully but I got the following exception

org.eclipse.core.commands.ExecutionException: While executing the operation, an exception occurred
...
Caused by: org.eclipse.core.runtime.AssertionFailedException: null argument:failed to create a view

Is there any way to get rid of that exception ?

Thanks,

Put a breakpoint in your custom code and debug it with f5 all the time and you will see how the exception is throwed (probably in a compiled class of the framework). I think the issue is that gmf creates the semantic element and his view because the editpart is the controller and use both for display the figure(image) and save the data(model element). You probably are receiving that error for this reason. Regards

Hi Fernando,

Thank you for your response.

The exception is because I didn't associate a view with the semantic model.

Because when I drag and drop a component from the palette,

CreateViewAndElementRequest is called.

So My question is now:
Is there any way to create the element without creating the view when I drag and drop the component from the palette ?

Thanks
