[news.eclipse.modeling.m2m] ATL:Multiple assignments in an iterator

[venkateshmvp@xxxxxxxxx (venkatesh )]

Hi,

 I have a rule in which


matichingRules :PdmModel!MatchingRules	(
			name<-'matchingrules',
			ldapMatchingRules<-LdmMetaModel!LDMAttribute.allInstances()->iterate(e; res 
: Sequence( PdmModel!LdapMatchingRuleType) = Sequence {} |
			        
	let rs:TupleType(rulename:String,oid :String)= 
thisModule.getmatchingrules(e.type).get('aprxMatchingRule') in
let rs1:TupleType(rulename:String,oid :String)= 
thisModule.getmatchingrules(e.type).get('eqMatchingRule') in
	if rs.oclIsUndefined()
	       if not res->collect(f | f.name)->includes(rs.rulename)then  
	         res->including(thisModule.ldapMatchigrule(rs.rulename,rs.oid))
		  else 
		     res
		 endif
	 else
	    res
	endif

       if rs.oclIsUndefined()
	       if not res->collect(f | f.name)->includes(rs1.rulename)then
	          res->including(thisModule.ldapMatchigrule(rs1.rulename,rs1.oid))
		  else 
		     res
		 endif
	 else
	    res
	endif))

Here i wanted to add rs,rs1 for each LdmMetaModel!LDMAttribute but mutiple 
if loop is not working 

before adding rs,rs for each LdmMetaModel!LDMAttribute i'll check if it's 
already exists to avoid duplicates.


can u help me

thanks
