rALF editor does not work in newly installed Eclipse

[tamasborbas]

rALF editor does not work in an Eclipse until a new opaqueBehavior/opaqueExpression is created with rALF body. After this the editor start working.

Reproduce the bug:

• Dowload and extract a new Eclipse
• Install common things from the update
• Import any example with rALF code from xUML-RT examples (eg.: Advanced Ping-Pong example model)
• Look at the body of any opaqueBehavior with rALF code (eg.: s2 state' entry behavior in Pong's state machine)

Workaround:

• Create somewhere a new opaqueBehavior/opaqueExpression is created with rALF body (the modification does not need to be saved)

For the workaround the model also has to be reopened after creating an opaqueBehavior.

Currently I'm not able to use this workaround, the rALF editor validation and syntax highlight is not working, and it discards all modifications.

The currently working workaround is to open the Window->Preferences->Papyrus->Embedded Editors preferences page, and press OK. Reopening the model is not necessary (reopening the opaque behavior is)
