Expected result:
The Update task should appear under Tasks after rejecting the task that is in Review.

Actual result:
The Update task does not appear. This issue is different from LPS-28064, because even after waiting or refreshing the page the Update task still does not appear (see Michael Han's comment).

This issue seems to be part of a bigger kaleo workflow issue. The reviewer cannot Approve or Reject the task without getting the console errors described in the description, and the tasks do not appear to be approved or rejected as they normally should be. In LPS-32929, Documents and Media documents and Blogs entries still have Pending status after being approved.

Caused by LPS-32688:
Portal 6.2.x GIT ID: a31b5d57b283a4bdba96b33511609a8611f307fe.

This regression is caused by a portal commit, not a commit to plugins. When doing root cause analysis, the following plugin GIT ID was used in all test cases:

Plugins 6.2.x GIT ID: 2e450671bd2de81e051fd7fcc939cc66e2eb605d.

Committed on:
Plugins 6.2.x GIT ID: d9ed7403a42a4eeac157e553588d013f2c4e0cd1.

[Kenji Heigel]

PASSED Manual Testing following the steps in the description.

Fixed on:
Tomcat 7.0.34 + MySQL 5. Portal 6.2.x GIT ID: 8fab771f4d55caa948ca1f6595347b2b328c5515.
Plugins 6.2.x GIT ID: a0e827c50c3a7048ce54d90d8a4c5e8f43de9d67.

The task that the user rejects now has a status of Update. Additionally, the general workflow of approving and rejecting tasks is working. No console errors occur. This should also fix LPS-32929.
