Hello,

I have a Sapphire (0.6.5) application that works fine when running with "Debug As ..." from the development environment.
It can also be installed into eclipse (as plugin, dropin, feature or whatever) without errors. But on opening the editor I then get "Failed to create the parts control" with a runtime exception:

Any idea what is missing or wrong?

In Sapphire 0.6.x and prior, an annotation processor must run during the build in order to generate model element implementation classes. The most common cause of the above exception is that implementation classes are missing from the plugin jar. For type somepackage.IDispatcher, the implementation class would be somepackage.internal.Dispatcher.

Compare your project metadata with Sapphire samples project. In particular, take a look at customBuildCallbacks.xml file as well as the related wiring in build.properties.

Hi Konstantin,

many thanks for answering. Indeed, annotation processing was not enabled ...

Seems there is one thing left. The editor opens as long as Sapphire itself is also installed. When I install my plugin to a fresh Eclipse (Helios, Kepler), opening the Editor fails. It turns out, that the fragment org.eclipse.sapphire.osgi.fragment_0.6.6.201310081535.jar is not installed with its host org.eclipse.sapphire.modeling_0.6.6.201310081535.jar.
(dropping in the fragment makes the editor work.)
How can I make sure that the fragment is installed? From the examples, I can't figure out that.

The fragment is part of org.eclipse.sapphire.osgi feature. Typically, you will want your feature to declare various Sapphire features as dependencies. Straight plugin dependencies aren't typically sufficient since you will not typically depend directly on all Sapphire components that you end up using.

Thanks again. After adding some Sapphire features to my feature it works fine.
