Thank you

Hi,

In ETL you can define operations with/without a context. Operations with
a context are defined like this:

// Class is the context here
operation Class doSomething() {

}

and invoked like this:

c.doSomething(); // Provided that that c is an instance of Class

Context-less operations are defined like this:

operation doSomethingElse() {

}

and called like this:

doSomethingElse();

I hope this helps.

Cheers,
Dimitris

Thank you for answering me.
But my problem is not exactly this.
In ATL I have " helper def: package ........ " and then it writes himself " model <-thisModule.package " and the equivalent one in ETL is: " operation package().... ".
But I do not know call like it is indexed in ETL, that is to say " thisModule.package " says to me that it does not exist.
I want to do " s. Model: = package (); " but me the mistake appears " Property 'Model' not found in object "

Hi,

Could you please send me your transformation together with the
metamodels and some sample models so that I can have a closer look at this?

Cheers,
