Editor cannot be initialized/Unresolved proxy [message #1179177] Sun, 10 November 2013 05:00 Go to next message

I am getting inconsistent behavior in my DSL editor in the second instance of Eclipse Kepler.

Sometimes when I open a DSL source file, it works fine. Other times, it won't open and I get an "Editor cannot be initialized" error. The issue follows specific files (it may be related to a specific instruction). If I restart the Eclipse session it might work OK or be a different set of files. So, some will open and other's won't within the same session.

At the same time, in the console of the first Eclipse instance, I see:

Caused by: java.lang.IllegalStateException: Unresolved proxy http://www.holycityaudio.com/spincad/SpinCAD#//Clr. Make sure the EPackage has been registered.


"Clr" is one of the parser rules. Sometimes it is one of the other parser rules, e.g. "absa". If I quit and restart the second instance of Eclipse, it might work on a file which had been problematic, or it might have a problem with one of the other parser rules.

Here are those rules in my Xtext grammar:

// zero argument instructions
Clr: {Clr} 'clr';
Not: {Not} 'not';
Absa: {Absa} 'absa';


Using Windows 7, 32 bit, 4 GB of RAM (3 GB that is).

So far, all I can tell you is that the rules which seem to be causing problems are the DSL instructions which take zero arguments, such as "clr" and "absa".

I restarted the second Eclipse again and it worked OK. However I get this exception in the console of the first Eclipse:

!MESSAGE com.holycityaudio.spincad.spinCAD.impl.SpinCADFactoryImpl cannot be cast to com.holycityaudio.spincad.spinCADMenu.SpinCADMenuFactory


Note that I have two DSLs in the same project (I ran "Create Xtext project" wizard twice). One is called "SpinCAD" and the other is called "SpinCADMenu". The above message implies to me that there is some confusion having the 2 DSLs side by side.
