Hi,

My source meta-model has two parts which links together.
When I want to transform an element of second part of this meta-model, it doesn't have error but nothing create in output. What can I do?

If you specify ETL.ecore as metamodel, ATL will also load any metamodels it refers to (I.e. EOL.ecore).

Cheers,
Dennis

I specified ETL as metamodel, but when I write e.g. "MM_ETL!AssignmentStatement" in the from part of my ATL rule, no element create in the output. if I change "MM_ETL!AssignmentStatement" to e.g. "MM_ETL!TransformationRule" or anything in the ETL part the elemet create in the output. I use version 3.6 of ATL.

When I register metamodels, the output is not generated whether transform the element of ETL part or EOL part. I have this error:
Error loading platform:/resource/Project/Model/Tree2Graph.etl.model: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.emf.ecore.impl.DynamicEObjectImpl@757faad7 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@1c2fa2f9 (name: NameExpression) (instanceClassName: null) (abstract: false, interface: false))' is not legal. (platform:/resource/Project/Model/Tree2Graph.etl.model, 35, 104)


The start of my Tree2Graph.etl.model file is like below:
<?xml version="1.0" encoding="ASCII"?>
<etl:ETLModule xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:eol="http://www.eclipse.org/epsilon/eol" xmlns:etl="http://www.eclipse.org/epsilon/etl">

You probably have an attribut set with an object of the wrong type (for example you have value="1" instead of value=1).
(platform:/resource/Project/Model/Tree2Graph.etl.model, 35, 104): this indicate the line and the column where is the element of your model causing the issue.
