Hi ,

I am new to ATL transformation.i have


TypeA.ecore (metamodel) TypeB.ecore(MetaModel)

| |
| |
typeA.xmi(sourceModel) typeb.xmi(targetModel)




TypeA.ecore file look like this


<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmi:id="EPackage1"
name="typeA" nsURI="platform:/resource/Port/Metamodel/TypeA.ecore"
nsPrefix="tpA">
<eClassifiers xsi:type="ecore:EClass" xmi:id="EClass2" name="testA">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="testAattr"
eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>


TypeB.ecore file look like this


<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmi:id="EPackage1"
name="typeB" nsURI="platform:/resource/Port/Metamodel/TypeB.ecore"

<eClassifiers xsi:type="ecore:EClass" xmi:id="EClass2" name="testB">

eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>



now i have create rule

-- @atlcompiler atl2006
module T_In2Out;
create typeBModel : typeB from typeAModel : typeA;

rule testA_2_testB2 {
from
v_left : typeA!testA
to
v_right : typeA!testB (
testBAttr <- v_left.testAattr
)
}


when i'm transforming it's giving the following error

Venky,

I've not been through all of your code, but the target
of the transformation rule being typeA!testB looks
wrong; I would have expected it to be typeB!testB
