when i generate getRule1() :
lazy rule Rule2Rule{
      from f:GrammAcme!Rule
	  
      to t:MMAcme!Rule(	
      	
      	
      	 ruletext<-thisModule.getRule1()

)}

  helper  def: getRule1(f:GrammAcme!Rule):String=
  	 if not f.designRuleExpression.qt.formalParam.oclIsUndefined() then

			  	else  OclUndefined endif

here i don't have a problem and i have this result :

Quote:

<rules ruletext="rule10 = invariant forall ps : PortTWSService in self.PORTS | (ps.Prec) =="/>




when i generate getRule3() i don't have a problem

lazy rule Rule2Rule{
      from f:GrammAcme!Rule
	  
      to t:MMAcme!Rule(	
      	
      	
      	 ruletext<-thisModule.getRule3()

)}

 helper def: getRule3(f:GrammAcme!Rule):String=
  if not f.oclIsUndefined() then
   	if not f.designRuleExpression.qt.designRuleExpression.oclIsUndefined() then
 	
 	if not f.designRuleExpression.qt.designRuleExpression.qb.oclIsUndefined() then

	else  OclUndefined endif 
				else  OclUndefined endif 
					else  OclUndefined endif 
				
		else  OclUndefined endif 
						  						  else  OclUndefined endif ;								  ;


i have this result :

Quote:

<rules ruletext="activer"/>

but when i concat getRule3() + getRule1() like this :

 lazy rule Rule2Rule{
      from f:GrammAcme!Rule
	  
      to t:MMAcme!Rule(	
      	
      	
      	 ruletext<-thisModule.getRule1()+thisModule.getRule3()
)}


i have this problem :

ATL dynamically looks up the '+' method, based on its arguments (unlike Java, which looks up methods statically). If your first String argument is OclUndefined at runtime, ATL tries to find '+' on OclUndefined, which does not exist.

The easiest solution is to return empty strings instead of OclUndefined in thisModule.getRule1() and thisModule.getRule3(). Alternatively, you have to perform oclIsUndefined() checks on both values before calling '+'.

Cheers,
Dennis

hi , i do that but thisModule.getRule3()+thisModule.getRule1() is

Quote:
<rules ruletext="rule10 = invariant forall ps : PortTWSService in self.PORTS | (ps.Prec) =="/>


thisModule.getRule1() is Quote:
empty !!!! the result is ''

You can't call a third function to merge them?
"ruletext<-thisModule.getRule1and3()" or maybe "ruletext<-thisModule.getRule1and3(thisModule.getRule1(), thisModule.getRule3())"
