Hi, 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 
		   if not f.designRuleExpression.qt.designRuleExpression.qb.oclIsUndefined() then
		  if not  f.designRuleExpression.qt.designRuleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression.additiveExpression
         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.oclIsUndefined() then
		 if not  f.designRuleExpression.qt.designRuleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression.additiveExpression
         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression
         .additiveExpression.multiplicativeExpression.unaryExpression.primitiveExpression.id.oclIsUndefined() then
  	
  	  f.nameRule +' '+ '='+' ' + f.typeRule +' '+ f.designRuleExpression.qt.typeExp + ' '+ f.designRuleExpression.qt.nameComponent
		 + ' '+':'+' ' +f.designRuleExpression.qt.formalParam.type

		 +'.' + f.designRuleExpression.qt.setExpression.set.toString().regexReplaceAll('Sequence',' ').replaceAll('{',' ').replaceAll('}',' ').replaceAll('\'',' ').trim()
		 +' '+'|' +' '+'('+

         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression

		+')'+' '+'=='
			  	else  OclUndefined endif 
				else  OclUndefined endif 
			
		else  OclUndefined endif 
						  						  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
 	if not f.designRuleExpression.qt.designRuleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression.additiveExpression
         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.oclIsUndefined() then
 
		 if not f.designRuleExpression.qt.designRuleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression.additiveExpression
         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpressions->first().
         oclIsUndefined() then
		
		
		
		f.designRuleExpression.qt.designRuleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpression.additiveExpression
         .multiplicativeExpression.unaryExpression.primitiveExpression.ruleExpression.qb.orExpression.impliesExpression.iffExpression.equalityExpression.relationalExpressions->first().
          additiveExpression.multiplicativeExpression.unaryExpression.primitiveExpression.id.idName
	  						
	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 :

Hi

I already replied to this on the Xtext forum suggesting that you need to ask on the ATL forum. This is not an OCL issue.
