[rules-users] Problems with Guided Rule Editor in Eclipse

[Vincent Legendre]

I have the same problem with BRL editor under eclipse. Also the action 
part dialog box does not show DSL phrases ...
The plugin is incomplete/buggy and shows errors but rules are correct 
(you can compile and run them).
This problem is the same since version 5.0. There is a JIRA for that 
since then ...
I don't know when a fix is planned, but my feeling is that nobody uses 
the guided editor under eclipse (dsrl editor works well and provide 
completions on facts and DSL sentences). But it is not easy when you 
have rules that comes from Guvnor ...
