Error description
When you trigger a boundary event on a coach, the navigation might fail with an exception. Depending on the human service model, an error handler might be triggered. Without an error handler, the service fails and you see an exception in the SystemOut.log file: [2/13/15 10:46:43:659 CET] 0000004f wle E CWLLG0594E: An exception occurred while initializing the runnable thread.

The problem occurs only when the coach you are looking at previously triggered another boundary event, causing the navigation to come back to itself. During this navigation, a property of an item in a complex object array was set to null.
Local fix
Problem summary
When a coach navigates to itself, the coach is not refreshed. Instead, only the data that changed during the navigation is sent back to the browser client. When the changed data includes a property of a complex object that is set to null, and this property is part of a list, this property is incorrectly set to an empty array. The next boundary event then sends this incorrect data back to the server where it cannot be mapped.
Problem conclusion
A fix is available for IBM BPM that returns the correct value. On Fix Central (http://www.ibm.com/support/fixcentral), search for JR52558: 1. Select IBM Business Process Manager with your edition from the product selector, the installed version to the fix pack level, and your platform, and then click Continue. 2. Select APAR or SPR, enter JR52558, and click Continue. When you download fix packages, ensure that you also download the readme file for each fix. Review each readme file for additional installation instructions and information about the fix.
