Workflow issues with TS 7.2.1

System

Hi,
We are trying to get our custom workflows working with TS 7.2.1. The problem we are running into is that the preprocessor and postprocessor external tasks are failing. These tasks call a java servlet which uses CSSDK 3.x to get an handle on the workflow and do some operations.

In debugging the issue, I found that the "modelerworkflowapi.jar" is not to be found anywhere including the TS sub folders or in workflowmodeller folders. Did this change as part of 7.2.1? I tried using the processmodel.jar but not with much luck.

Any clues/ideas is greatly appreciated.

Thanks
