Start a job adding naginator auto-rebuilding after failure e.g. 2 times.
echo properties shows:
BUILD_CAUSE=MANUALTRIGGER
BUILD_CAUSE_MANUALTRIGGER=true

Add exit 1 or something to fail the build. Autorebuild will restart the job and echo properties shows:
BUILD_CAUSE=NAGINATORCAUSE
BUILD_CAUSE_NAGINATORCAUSE=true

Perfect. But:
Press "Rebuild" button on the job page to rebuild the failed build will not reset the build cause to manual triggered. Build cause is still naginator...

Please either check this behavior in the unrelased (1.9) feature for badgets or reset the naginator-variables each time the "rebuild" button is pressed.

Background:
for adding the badge we're using the groovy script:

if(manager.logContains(".*env.BUILD_CAUSE=NAGINATORCAUSE.*")){
    manager.addBadge("redo.gif", "Restarted by Naginator (Autorebuild)")
}

which is not working in this case.

Thanks
