Hi,
I want to apply design pattern to UML classes.
In this situation, source and targed metamodels are the same (UML Metamodel).
when I tried to do this, I got an error.
I start with a simple example, but it didn't work.
Content of my etl file is:
pre{
"Running ETL".println();
var pk : new OO!Package;
}
post {
"Running Successful".println();
}
rule Class2Class
transform c : OO!Class
to t : OO!Class {
t.name = c.name;
t.package = pk;
}
and content of my launch file is:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration type="org.epsilon.etl.eclipse.dt.launching.EtlLaunchConfigurationDelegate">
<booleanAttribute key="fine_grained_profiling" value="false"/>

when I tried to run it, I got following error.

I've registered my OO.ecore package.
Is it possible to use same metamodel for source and target models?
as an another test,
when I create a new instance of OO.ecore and rename it to "DB" and use it as target
model, it works fine, but if I rename it to "TargetOO", it doesn't work!!!
(I've created DB.emf and DB.ecore and I've register it as for "TargetOO" )
