[news.eclipse.technology.gmt.amw] Re: problem extract AM3

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hello,

the problem is not with the extraction, but the atl model (.ecore) is not complete.

First it misses a name for the two "ocl:Model" elements at the end of the transformation. This is the name that appears in the CREATE part:

   <ocl:OclModel model="/0/@inModels.0" name="first name"/>
   <ocl:OclModel model="/0/@outModels.0" name"second name"/>

create OUT: <the first name comes here> from IN: <the second here> ;

Second, there is no type in the inPattern and outPattern elements.
To illustrate this, I generated an ATL file using the latest versions of ATL and AM3 from the CVS, and I got the transformation below.

rule {
  from
    Agrupacion : there is no type
  to
    Vista : there is no type
}

According to the ATL metamodel, a "SimpleOutPatternElement" inherits from "VariableDeclaration", that must have a type
So, the .ecore should have something similar to the bold part below, for every in and out patterns:

<outPattern>
        <elements xsi:type="atl:SimpleOutPatternElement" varName="Vista" id="Vista">
              <type xsi:type="ocl:OclModelElement" name="TypeName" model="/5"/>
        </elements>
</outPattern>

<ocl:OclModel model="/0/@inModels.0" name ="abc"/>
  <ocl:OclModelElement name="TypeName" model="/1"/>

If you are using the HOT from the KeysToNested example, you can send and excerpt of the input weaving model. It is probably missing some attributes.

Regards,
Marcos.

Hi,

I have problem extracted ATL file, I use AM3 version 1.0.0 with eclipse 3.1.1

I attach .ecore conform MMATL and .atl

Thanks for your help,
