| [SOLVED] AbstractFXEditor throws ClassNotFoundException via o.e.g.mvc.fx.ui [message #1782869] |

Hi,
I'm currently trying to build a GEF 5.0.2 editor on a compatibility RCP app based on Neon.
For this I'm trying to use an extension of AbstractFXEditor bound to a file extension via plugin.xml (just like in the old days).
I've set -Dosgi.framework.extensions=org.eclipse.fx.osgi (which got rid of the initial FXCanvas error), but when trying to open a file, I get a ClassNotFoundException on javafx.beans.value.ChangeListener from o.e.g.mvc.fx.ui.
Any ideas?
This is giving me a headache, and I'm happy to provide any further info that may be needed. Thanks!

So in the end I decided to roll back to using AbstractFXEditor for convenience, and I managed to get that setup to work as well, without having to resort to the dreaded BuddyPolicy.
Based on Dirk Fauth's cookbook recipe (thanks Dirk, not only did you give us NatTable, but also saved my day with this recipe), I did the following:
- Add the e(fx)clipse E4 Target feature to the target definition (org.eclipse.fx.target.rcp4.feature.feature.group, from http://download.eclipse.org/efxclipse/runtime-released/2.6.0/site/)
- Add the feature to the product definition
- Add the VM argument -Dosgi.framework.extensions=org.eclipse.fx.osgi to the product definition
Note that I didn't have to import any javafx* packages (in fact, when I did, I got the "deprecated binding" warning WARNING: You are binding against the deprecated org.eclipse.fx.javafx - please remove all javafx imports).
Works like a spell!
UPDATE: Well, works like a spell after I've changed -Dosgi.framework.extensions=org.eclipse.fx.osgi to -Dorg.osgi.framework.bundle.parent=ext. Funnily enough, the former works fine on Linux OpenJDK, the latter is needed for Windows 10 and Oracle JDK.
