Specify a Brief Description

Compiler crashes (both in Umple Eclipse and in UmpleOnline) with IndexOutOfBounds exception when trying to parse the following piece of code where guards in three statemachine transitions indirectly refer to objects accessed via named associations.

Give the minimum Steps to Reproduce

  1. Parse the following minimal working example:
    (The problem disappears if one comments out any of the three transitions!)
class OtherClass {
  Integer row;  

class Statemachine {
  * -> 1 OtherClass other;
  Boolean cond; 
  sm {
    s1 {
      event1[cond && other.row > 4] -> s2;
      event1[cond && other.row == 3] -> s3;
      event1[cond && other.row == 4] -> s1;
    s2 {}
    s3 {}

Describe the expected result that didn't happen

Expected results:
A statemachine rendered/parsed with three states and three outgoing transitions.

Actual Result

Actual results:
stack trace
