I am using eclipse luna (4.4) with the Antlr4 plugin with Xtext 2.6.2
I already built a simple grammar to test the grammar and look at a parse tree. Antlr4 does include a parse tree view for that.
I have already seen the answer in this post:
How can i see the live parse tree using Antlr4 Ide in Eclipse?
The point is that when I do what is described in the answer the right field of the parse tree view stays empty.
start: exp EOF;
exp : exp '+' exp | ID;
What could be the problem?
I have not found any solution for eclipse.
But what I did was changing to Intellij, where the plugin works fine including the parse tree view.
