Hello,

I'm new in ATL. I'd like to know whi I get Empty Stack Exception when
launching next transformation:

module uml2dsl; -- Module Template
create OUT : scxml from IN : uml;
entrypoint rule trans() {
to r : OUT!DocumentRoot (
)
do {r;}
}


Thanks in advance,

Ander.


This is the console output:

INFO: Trying to connect to remote debuggee
INFO: Connected.

Hello,

There is an error in the model element syntax:

OUT refers to the model, which metamodel is scxml. As the DocumentRoot
element is defined into the scxml metamodel, the correct syntax is:

to r : scxml!DocumentRoot (

Best regards,

William
