Dear all,

I started experimenting with XText over Easter but I found a mysterious bug in the Domain-Model example:

Steps to reproduce:


  1. Download the Eclipse version from the www.xtext.org/downloads Windows 64-Bit and install it (I'm using Windows 7 with jdk 1.7)
  2. Create the demo project via New->Xtext->Examples->Xtext Domain-Model Example
  3. Generate the classes by launching the GenerateDomainmodelLanguage.mwe2
  4. Start the Runtime Workspace (had to apply -Xmx1024m -XX:MaxPermSize=256m as vm arguments)
  5. Create a Java Project
  6. Create a file 'sample.dmodel' in the src folder


At this point xtext asks to apply the nature which was a good sign.

The language is also recognized. When I enter the following lines

package org.test {
	entity Test {
		one: String
		two: Integer
		op runHere() {
			val test = 4;
			if (test < 5) {
			  // expression of if-clause is marked as error
			}
		}
		
	}
}


an error marker is applied to '<' saying

'<'(int) is undefined


The code completion and everything else works, just the if statements seems to be buggy.

What am I doing wrong?

Have a nice easter weekend,

Stephan

Hi,

did you add xbase lib to the classpath of the project with the dmodel file?

Yes, that solved the problem. Thanks Smile

But I couldn't find anything on the documentation (neither in the tutorials or in the forum). Only the bug ticket Wink
