Dear all,
I'm writing the following transformation rule based on the
information provided in
http://wiki.eclipse.org/index.php/ATL_FAQ#Full_name_referenc e_to_metamodel_classes

rule ADT {

from
dc : enumerationDC!DCEnum

to
coopnmodule: COOPNMetaModel!COOPNMetaModel::ADTModule::COOPNADT(
name<- 'MyCOOPNModule'

)

}

I get the error "No viable alternative at input :" in
"COOPNMetaModel!COOPNMetaModel:"

My Metamodel is named "COOPNMetaModel and is defined as follows:

package COOPNMetaModel {

class Module {...}

package ADTModule {
class COOPNADT {
attribute name : String;
}
}
}

Shouldn't my rule work? Any hint how to solve this problem?

Thanks very much in advance for your time.

Best regards,

Luis Pedro

Hello,

In fact the MM!pck1::pck2::ME form isn't well recognized by the ATL
parser...
So you need to use the " around the model element location expression :
MM!"pck1::pck2::ME"

in your case :
COOPNMetaModel!"COOPNMetaModel::ADTModule::COOPNADT"

I updated the wiki, thanks for reporting this error !

Best regards,

William
