Hello guys, I was interested in create a new model elements in refining model... I was searching and I was able to found that I should use the "including" instead of "newInstance()". As can be seen in the source code bellow the first including works pretty good. However, when I need to create another element inside of the earlier created I got an error message like this: org.eclipse.m2m.atl.engine.emfvm.VMException: Feature codeElement does not exist on Element

What am I doing wrong? Can someone help me? Thanks in advance.


module testingAllURI;
create OUT : build, OUT1 : code, OUT2 : conceptual, OUT3 : core, OUT4 : data, OUT5 : event, OUT6 : kdm, OUT7 : plat, OUT8 : source, OUT9 : structure, OUT10 : ui, OUT11 : action refining IN : build, IN1 : code, IN2 : conceptual, IN3 : core, IN4 : data, IN5 : event, IN6 : kdm, IN7 : plat, IN8 : source, IN9 : structure, IN10 : ui, IN11 : action;


rule addClassToPackage {
	
	from 
		source : code!Package (source.name = 'testelucas')
	to
		target: code!Package (
			codeElement <- source.codeElement->including(newClassUnit) //here it works
		
		),
		newClassUnit: code!ClassUnit (
			
			name <- 'theNameOfTheClasse',
			codeElement <- newClassUnit.codeElement->including(newStorableUnit)//I got the error here....
		
		),
		newStorableUnit: code!StorableUnit (
			
			name <- 'theAttribute'
		
		)
		

}

"newClassUnit" is a new element: newClassUnit.codeElement will be empty, so you should not write the "including" code, but "Sequence{newStorableUnit}" instead.

In ATL, you should not read properties of a "to" element, only the "from" elements are readable.

Cheers,
Dennis

Although it worked, I would like to create a helper for every time create a storableUnit. What is better way to do this? I mean, I would like just to call something like this thisModule.createStorableUnit(theNewName....)

I've tried it out.. however I just found that lazy rules are not accepted in refining model. Thus, what is the best way in this case?

Thanks a lot.

I just read the section that even atl2010 does not support lazy rules in refining mode. You can use EMFTVM then, which does support lazy rules in refining mode.
