EWL: How to run a sample wizard in UML Designer & Eclipse Mars [message #1718249]

Hi,

After studying the EWL chapter of the Epsilon Book, I want to explore a small example wizard just as follows:

wizard applySignletonPattern {

	guard : self.isKindOf(Class)

	title : "Apply the Singleton pattern to " + self.name

	do {
		"It's Okay! Let's go and apply that.";
	}
}

How can I run this wizard?
Of course, I have named it 'foo.ewl' in a UML Designer sample project. In addition, I have created a class in my model. What should I do after selecting my candidate class for applying pattern, i.e., here wizard "applySignletonPattern"?

Kind regards,
Alireza

Sorry, I didn't see the message [#1696197] which discusses how to run an EWL wizard.

Kind regards,

Hi,

My wizard settings have problem with the UML Designer 5 in Eclipse Mars. The wizards menu in the pop-up menu is empty!

index.php/fa/24395/0/

Is there any required specific settings for my platform environment?

Kind regards,
Alireza

Hi Alireza,

Epsilon doesn't provide built-in support for UML Designer and it appears that although Sirius (on top of which UML Designer has been developed) builds on GMF, it adds one more layer between the diagram and the semantic elements which Epsilon is unaware of. To cut a long story short, a workaround for this is to set the Namespace URI field to * in Preferences->Epsilon->EMF/GMF Wizards and then use self.target to navigate to the actual semantic elements, as follows.

wizard AddSuffix {

	guard : self.target.isKindOf(Class)
	
	title : "Add suffix"
	
	do {
		self.target.name = self.target.name + "_";
	}
	
}

Cheers,
Dimitris

Hi Dimitris,

Great. Thank you very much.
But, there is one more thing! When I run the wizard from the menu, the error message
Undefined variable, type or model: 'Class' is displayed. Did you see this error message too?

Kind regards,
Alireza

Hi Alireza,

That might be because there might be several metamodels with a type named "Class". Could you try prefixing it with the appropriate namespace URI? For instance, for EMF/UML2 5.0.0 models, it'd be something like this:

`http://www.eclipse.org/uml2/3.0.0/UML`::Class

Kind regards,
Antonio
