Hi All,
Could any one please let me know the reason of the following issue. When i made a small change in existing process model (Adding Chaining in between two tasks) and try to publish that it is showing following error
"There was an error in an expression in null at null : null"

Please let me know the possible reason and solution to fix this.

Thanks,
Ravi

I believe error is not related to chaining.Have you deleted any process variable recently.

Please check your custom alert settings, remove the group constant mentioned for alert notifications and try to put it back. Process model refers to deleted version of the constant and throws the error. This is one of the root causes, you can follow similar method of eliminating root causes by checking other objects.

Once you click Tools - Validate in the Process Modeler when viewing the model, the bottom status bar will show you a better error message.
