Hi,

How can I select if an element oclIsTypeOf(...)? when I use asSequence(),... it has an error.
To Clarify, In the below code I want to transform "AssignmentStatement" which its lhs.oclIsTypeOf(MM_ETL!PropertyCallExpression) and then set another conditions that is related to "lhs.oclIsTypeOf(MM_ETL!PropertyCallExpression)", How can I do that?

from 
		b : MM_ETL!AssignmentStatement
		  ( OUT_MM!EClass.allInstancesFrom('IN3') -> ...  ->select(t|t.name.name=[color=red]b.lhs.target.name[/color])->....

if I don't put the condition that I explain above, the selected code has an error.

Hi,

Maybe you should check before if lhs is defined nor is type of what you want?

from 
		b : MM_ETL!AssignmentStatement
		  (  if b.lhs.oclIsTypeOf(MM_ETL!PropertyCallExpression) 
then OUT_MM!EClass.allInstancesFrom('IN3') -> ...  ->select(t|t.name.name=[color=red]b.lhs.target.name[/color])->....
else false endif

or if the problem is in your ocl expression, add some select (like ->select(t|t.oclIsTypeOf(MM_ETL!PropertyCallExpression)) ) before your select where you have a truble.
