Loading model instances from different ecore projects [message #538753]

Hello,
I have two ecore models in two eclipse models/projects (Dimensions and DataStore). I added some src to load model instances by code in project in my Dimension project. This works quite well in the Dimension project and I am able to iterate my model elements, that I defined.
In my DataStore model I refer to Ecore elements that were defined in the Dimension model.
In the DataStore project I also added some Code to iterate DataStore instances. And I also called the code for iteration of Dimension in the Data Store project. But when it is started from DataStore project, the following exception is raised: (the aisId is my Id for all modeled elements)

org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'aisId' not found. (file:/C:/Lib/ModelElements/ZeitNeu.automaisdimension, 2, 178)
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
	at java.util.ArrayList.RangeCheck(Unknown Source)
	at java.util.ArrayList.get(Unknown Source)
	at AutoMaisCubeStore.StoreCubeDimension(AutoMaisDataStore.java:81)
	at AutoMaisCubeStore.main(AutoMaisDataStore.java:50)

The question is: why is it possible to run the code from the Dimension model but not from the DataStore Model?
Here is the code that I use to load Dimension instances

AutoMaisDimensionPackage pack = AutoMaisDimensionPackage.eINSTANCE;
			ResourceSet rs = new ResourceSetImpl();
			rs.getResourceFactoryRegistry().getExtensionToFactoryMap().put
			("automaisdimension", new XMIResourceFactoryImpl());
	 		URI fileURI = URI.createFileURI(new File(aFile.getAbsolutePath()).getAbsolutePath());
			
	 		Resource myPort = rs.getResource(fileURI, true); // <== cause exceptionight here

Thanks!
Yvette

Hi,
is the Feature aisID part of the dimension model then? Can it be that in
the secon project the dimension model is not loaded or accessible, or
that the package dimensions is not registered?
Cheers

The Feature aisID part of the dimension model. I thought the second model will by loaded by its one code. But what I did in my second project to load the dimension model

AutoMaisDimensionPackage test = AutoMaisDimensionPackage.eINSTANCE;

What Do you mean with registered?
Thanks

I found out! I have to say that I started developing java again only a few weeks ago.

The cause of my error was, that I had the wrong version of generated Dimension source code in my dataStore model, And in this the id was not defined,
So thanks again
