[EVL][EOL] Method not found [message #1572057]

Hi,

I'm creating a validation plugin (based on the "Live validation and quick-fixes in GMF-based editors with EVL" article). My EVL file has the following content:

context NetworkNode {
	constraint hasCapitalName {
	 		
		check : self.name.toUpperCase() = self.name
		
		message : 'Name ' + self.eClass().name + ' is not in capital.'
	
	}	
}

However, when I try to validate my model, the following exception occurs:

Method 'toUpperCase' not found

Am I missing something?

Hi Felipe,

Apologies for the slow response - this somehow slipped past the radar. Is there any chance that self.name is returning null?

Cheers,
Dimitris

Hi,

Currently I am working with ETL files and when I execute them everything works fine.

In addition, I wanted to made some control modifications to a model with an EOL program. I have the following code structure:

operation1();

operation operation1(){
 //calls operation2
 operation2();
}

operation operation2(){
 //does something
}

When I execute the EOL program I obtained a "Method 'operation2' not found". The model is being read but the operations are not found. I don't understand why this is happening. Do you have any clue?

Hi Lina,

Could you please provide a minimal example [1] we can use to reproduce this?

Cheers,
Dimitris

Hi Dimitris,

Sorry, It was my fault. I was declaring operations like:

operation Integer method1() {
 ...
}

Instead of:

operation method1() : Integer {
 ...
}

Everything is fine now. Thank you.
