User task is automatically rejected

[tim1234]

I am a newbie and currently using Alfresco newest community edition. 

I have been trying to recreate a simple review (approve/reject) task for later use. It is not a timed task. Once I assign the task, it is instantly rejected automatically.
Inside my repo-tier bpmn, I have copy some fragments from some sample codes:

why execution.setVariable('wf_reviewOutcome', task.getVariable('wf_reviewOutcome')); dont work?
(let's assume share-tier part is setup correctly)
I appreciate any help or advice!

Hi, @Tim Lam! 

Try to use

execution.setVariable('wf_reviewOutcome', task.getVariableLocale('wf_reviewOutcome'));

If it doesn't helps attach please model of your workflow.

Good luck!
