EMF Forms: PackageNotFoundException for view proxy model [message #1756019]

I am trying to use EMF Forms View Proxies in an ECP project but it seems the view proxy model is not available.

Error:
org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://org/eclipse/emf/ecp/view/viewproxy/model' not found.

Versions:
EMF 2.10.2
ECP 1.9.0
EMF Forms 1.9.0

My Eclipse product is based on features, org.eclipse.emf.ecp.emfforms.runtime.feature is included. All ECP and EMF Forms stuff basically works. The exception is thrown when I open the editor for a model element that uses a view proxy of its base class. The base class attributes are not shown, instead the above exception is thrown.

Let me know what information you need in addition.

Thanks, Wernke

[edit] Sorry I made a mistake. The view proxy is not one of a baseclass but of a referenced class. This can't work without somehow linking a feature to the proxy. But the error message indicates some other problem.

Hi,

the view proxy sub model is not in the core SDK, you please make sure, that you have it in your target. Further, you need to make sure, that the bundles (ideally the feature) is contained in your product/run config.

Best regards

Thanks, Jonas.

I did not have any problem with the SDK, but with the runtime. I find it strange that the SDK contains the view proxy model but the runtime does not. I added the view proxy feature to the target platform, and it is working now.

Hi,

how is your runtime configured? We strongly recommend to configure your product feature based to avoid such missing bundles.

Best regards

Hi Jonas,

my runtime is based on a product requiring these features:

I had to manually add the org.eclipse.emf.ecp.view.viewproxy.feature (selected) to make it work. I had expected it to be contained in the ecp feature. But never mind, the problem is solved. Smile

Cheers, Wernke
