Hello ,

I am trying to test a transformation that works, with a single rule that works but with duplicates.
Inpout model I have two instances (2 tasks) but as a result it gives me 4 instances (4tasks).

How I can group many elements into one


Here is a file that will give you more information about my model

Any help would be very useful to me

rule taskss{

from e:MM!task , t: MM!A
to
r:MM1!task( id <- e.name, text <-t.text1)

}

In other words a task contains a description, the latter contains an Action element that inherits three elements A, B and C.

How from a Task element access to an attribute of an element A
When I try this syntax does not give me anything :

Task.Description.Action.A.text1

Your rule matches the Cartesian product (i.e. all combinations of) 'e' and 't', without any guard on the relationship between 'e' and 't'. If you just mean to trigger the rule for all 'e', you should specify 't' in the "using" section of the rule instead:
rule taskss{
  from e:MM!task (
    not e.description.oclIsUndefined() and
    e.description.action.oclIsKindOf(MM!A))
  using {
    t: MM!A = e.description.action;
  }
  to r:MM1!task (
    id <- e.name,
    text <- t.text1)
}


Cheers,
Dennis

Hi Dennis,
I had the same problem as Joe and i tried the solution proposed by you.
I had an error after closing ' }' related to the clause "using"
using { ........ }
"mismatched input '}' expecting SEMI"
I don't understand where does the problem come from.
Any help please?
Thanks

Oops! I made a syntax error, and forgot a ';' (SEMIcolon). I'll fix it in the original comment.

Cheers,
Dennis
