I have only another helper ?hasStereotype? which I tested separately and 
works fine. I attached the whole transformation file.


---This helper define the method "hasStereotype"
helper context UML!"uml::Element" def: hasStereotype(stereotype :
String) : Boolean =
self.getAppliedStereotypes()-> exists (c | c.name = stereotype);

---This helper define the method "getTaggedValue"
helper context UML!"uml::Element" def: getTaggedValue(stereo :
String ,tag : String) : UML!"uml::Element" =
self.getValue(self.getAppliedStereotype(stereo),tag);

---This helper verifies if the value of the proterty 'myProperty' is 
different of 'value1'
helper context UML!"uml::Element" def : checkMyPropertyValue() : Boolean =
	if (self.hasStereotype('MyStereotype')) then
   	if (self.getTaggedValue('MyStereotype','myProperty')<>'value1') then
		     true
		else 
	    	false
		endif
	else
		true
	endif;

rule Copyclass{
	from
		s : UML!Class   (s.checkMyPropertyValue())
	to   
		t : UML!Class( 
			name <- s.name
		)
}
