Assignment problem for work class with multiple keys



There appears to be a problem in the activity acquireWorkObject which incorrectly parses an instance handle string for all work objects which have multiple keys. The activity assumes there is one exclamation mark in the instance handle string, instead of one or more exclamation marks.

Error Messages

The work object class_name work_object_id could not be opened: Unable to open an instance using the given inputs: class_name work_object_id

Steps to Reproduce

  1. Create a work object instance of work class with two (or more) keys.
  2. On the Case Definition tab for the work class, add an optional action.
  3. Open the work object instance in a review harness.
  4. Click on the Actions menu, and then click the name of the optional action that was added to the case definition rule.

Root Cause

An issue in the custom application code or rules.


Multiple keys are not supported in this scenario. Only a single key should be used.
