[SOLVED] UnsupportedOperationException on enum [message #1396571]

Hi!

I've written a grammar and it works fine except with one thing. There is an enum that represents basic units and every time i try to use it, the editor shows up with an UnsupportedOperationException as error.

Relevant part of grammar:

IntLiteral:
	value=DECINT (SQUARE_PAREN_L unit=BaseUnit SQUARE_PAREN_R)?
;

BaseUnit:
	uName=UnitNames
;

enum UnitNames:
	UNITLESS="_" | UNITLESS="unitless" | BYTE="B" | SECOND="s" | METER="m"
;

The grammar is based on an existing model.

Everything I write within the square-brackets (SQUARE_PAREN_X) is marked as an Error and shows UnsupportedOperationException.

Any idea why this is showing up? I have no clue here...

thanks in advance
Jonas

Hi!

Sorry... I didn't notice the answer because I forgot to tick the Notification box... But problem is still there...

Here are the terminals you requested:

terminal DECINT returns ecore::EInt: 
	'0' | ('1'..'9') DIGIT*
;
terminal SQUARE_PAREN_L : '[' ;
terminal SQUARE_PAREN_R : ']' ;

And unfortunatly I can't give you a StackTrace because the exception just appears in the editor...
by the way: It might not be an error concerning enums because already the expression "4[]" is stating an "UnsupportedOperationException". Using the rule without a unit works fine.

Greetings
Jonas
