[IGSTK-Users] State Machine Validation Failure

Charles,

Attached are 2 .java files. IgstkvtMergeList.java goes in directory 
$IGSTKVT_HOME/src/org/igstk/validation/simulator/rules and 
IgstkvtGeneratorTest.java goes in 
$IGSTKVT_HOME/src/org/igstk/validation/simulator/util

These will be checked into CVS as soon as I resolve a permissions problem with 
the cvs administrators.

After copying these in the proper place, do an "ant run-smviz" and it will 
compile these files in and run the application.

The defect has been logged in the Mantis defect tracker as 0010144. Essentially 
the problem was a faulty list merging implementation in IgstkvtMergeList, I 
changed it to one that simply concatenates sendEvent lists together. When you 
run with your files and select animate, you should see SM1 on the bottom animate 
through 77 events first, and then SM2 at the top animate through its 17 events.

Please let me know how it works for you.

Kevin
