[EMF Forms] - Custom Control Area [message #1759991]

Hi,
I'm having an issue while creating CCAs based on the example.
I'm getting the following exception

!ENTRY org.eclipse.emf.ecp.view.model 2 0 2017-04-20 18:25:27.633
!MESSAGE Databinding not possible due to: The provided ECPHardcodedReferences from Bundle xxxx Class null cannot be resolved..

Anything specific that should be done for the view model to recognize the plugin

Eclipse oxygen/EMF Forms 1.12
Thanks
Sri

I was able to fix the above issue by redifining the target definitions. However I'm getting the similar error to below.

org.eclipse.emfforms.spi.core.services.databinding.DatabindingFailedException: The provided ECPHardcodedReferences from Bundle org.eclipse.emf.ecp.view.custom.ui.swt.example Class org.eclipse.emf.ecp.view.custom.ui.swt.example.MyCustomControl cannot be resolved.

Hi Sri,

could you post the relevant portion with the custom control definition of your view model?
Could you also include the corresponding referenced part of your domain ecore?

Could you also explain what you are trying to achieve and why you are using a CustromControl Element for this?

Cheers,
Eugen

Hi Eugen,
Thanks for the reply.

I'm trying the examples provided by ECP in eclipse.

I'm getting the above error when I was trying to associate a new Custom Domain Model reference as described in the
tutorial.

The error only occurs during the association of model reference. If you ignore errors and try to run the example it works.

Not sure if the view model project couldn't find the new CCA model reference.

My use case was to create a new tree control based on the emf model.
The emf model only contains paths but I need to display a tree with checkboxes.

Thanks
Sri

Hi Sri,

Do I understand correctly that you get this error in the Preview?
This is an expected error then, we already have a bug open to fix this: Bug 484106
The problem is that the bundles are not on the class path so we cannot find them.

Cheers,
Eugen

That is correct. Thanks so much. Its a development issue NOT runtime.
