Description Colin Snook CLA 2010-07-22 06:21:50 EDT 
re: http://www.eclipse.org/forums/index.php?t=tree&th=172367&start=0&
 
Using 2 guarded rules for  2 alternative cases and populating  relevant containments by parameterised equivalent("rule") operations. It works fine if I only have one or other case but as soon as I have both cases I get an ArrayStoreException. (I also tried using the target type as the parameter instead of the rule name but this gives exactly the same problem).

context.sets = tbuml_model.classes.equivalent("class2set"); //CORE!CarrierSet);
context.constants = tbuml_model.classes.equivalent("class2constant"); //CORE!Constant);


rule class2set
transform class : TBUML!Class
to set : CORE!CarrierSet {

guard : not class.generalization.isDefined() 

set.name = class.name;
}


rule class2constant
transform class : TBUML!Class
to constant : CORE!Constant {

guard : class.generalization.isDefined()

constant.name = class.name;
}


Here is the exception:

Comment 1 Dimitris Kolovos CLA 2010-07-22 06:46:19 EDT 
Thanks for reporting this. I'll have a look at it and provide a fix shortly.
Comment 2 Colin Snook CLA 2010-07-22 12:30:01 EDT 
Possibly related:-

I also found a similar exception when adding a set of equivalents to a containment....e.g.

	machine.events.add(tbuml_model.signals.equivalent());

I did this instead which works...
	machine.events = tbuml_model.signals.equivalent(CORE!Event);
	machine.events.add(0,machine.initialisation(tbuml_model));
Comment 3 Dimitris Kolovos CLA 2013-06-01 03:58:42 EDT 
Fixed in the latest interim version.
Comment 4 Dimitris Kolovos CLA 2013-09-01 08:16:49 EDT 
Fixed in 1.1
