Hi Marcos, a short question over an issue I can't figure out. 
Out of this weaving metamodel extension: 
 
package mm_weaving_JP { 
 
class WeavingModel extends WModel { 
 
    -- @subsets wovenModel 
    reference coreModel container : WModelRef; 
     
    reference adviceModel container : WModelRef; 
} 
 
class CombineResource extends WLink { 
 
    -- @subsets end 
    reference baseResource [*] container : Resource; 
     
    -- @subsets end 
    reference createAction [*] container : Action;  
} 
 
class Resource extends WLinkEnd { 
} 
 
class Action extends WLinkEnd { 
} 
} 
 
<big>And the following code: 
 
rule CombineResource { 
from 
         mmw : AMW!CombineResource ( not
mmw.baseResource->first().getReferredElement().oclIsU ndefined() ) 
 
Why <big>am I getting this error?: 
 
ERROR: could not find operation
getReferredElement on AMW!Resource having supertypes: [AMW!WLinkEnd,
OclType, OclAny] (including Java operations) 
 
Isn't the operation supposed to be available on a
WLinkEnd subclass? 
I'm having some trouble with AMW, and I'm trying to go back to my basic
assumptions. Thank for your help. 
Regards, 
                 Juan Pedro

Hello,

when you configure the transformation (in the launch configuration of
Eclipse), it is necessary to choose AMW Model Handler (instead of the
default EMF model handler).

The AMW model handler register these operations for the weaving model
elements.

Regards,

Marcos.
