XBASE content assist inconsistent behavior [message #1786425]

Dear all,

Sorry for bothering you again but i have encountered strange (=newbie) problem that is bothering me for more than a week now.

I have the following simple grammar

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.xbase.Xbase

import "http://www.eclipse.org/xtext/xbase/Xbase"

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model:
	greetings+=Greeting*;
	
Greeting:
	'Hello' name=ID '!';

AS you can see it simply the one generated by eclipse but i have replaced the usage of terminals with the usage of XBase.

In the first screenshot (with terminals no Xbase )
index.php/fa/32747/0/

you can clearly see that content assist works after the work hello and suggests the word 'name' as a possible option. Same after the word name it suggests the symbol "!"

After i introduce Xbase content assist stops working for both name and the "1".
index.php/fa/32748/0/

Console is clean from any errors and i cant find any other errors anywhere.

Any ideas about this specific problem?

Also i assume that there is somekind of way to introduce more detailed logging in order to troubleshoot this type of problems (e.g. force eclipse to stop as soon as it encounters an exception, tracing etc). Can someone give me a direction on an introductory level article about debugging/troubleshooting my dsl?

Thank you again!
Thomas
