Changing Task name in the editor does not update transitions that target this node

• Type: Bug
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: 3.1.2
• Fix Version/s: 3.2 M1
• Component/s: Kaleo Designer
• Labels: None

1) Open the basic "Single Approver" workflow in the editor (PFA) in Liferay Developer Studio
2) Change the name of task "update" to "update_2"
3) Go to workflow source and notice that the "target" attribute of transition "reject" is still set to "update" instead of "update_2"
4) Try to upload the updated definition to Liferay DXP(you'll get the exception) /Go to Control Panel - Configuration - Workflow Definition)
5) Click Save

The operation fails to complete and the following exception can be seen in the log:
