I have .genmodel loaded into my egl template but not able to fetch in contents.
What should be syntax to read the attributes from the .genmodel.For instance,generating all the genPackages from the .genmodel.The below code seem to be wrong and gives be a java.lang.NullPointerException when executed.

[%
for(a in Class.allInstances)
out.println(a);
%]

Vrm,

Class isn't a valid type in the GenModel metamodel. Did you perhaps mean GenClass.allInstances?

By the way, Epsilon provides the EPackage Registry view, which allows browsing of all registered metamodels. It's very handy for seeing which types are defined by which metamodels. You can the EPackage Registry view by clicking Window > Show View > Other... and then typing EPackage Registry in the filter box. Click Ok, and then hit the refresh button (the two yellow arrows) in the resulting view.

Here's a screenshot of the EPackage Registry view showing all of the types in the GenModel metamodel.

Cheers,
Louis.
