taskflow exception handling in ADF/Webcenter project

Hi All,

I am aware of taskflow handling by marking activity as Exception handler. What’s the best practice in the case, taskflow is used in Webcenter project.In our application, we using webcenter portal framework application and several adf taskflow deployed as shared libraries and used/ called in BTF in webcenter portal framework application. In this case, what’s the best practice to use exception handler. Should each taskflow deployed as shared library have an exception handler or only the main taskflow in WCP framework application.

I am getting error like

ADF: Duplicate Exception Handler Detected.

Please suggest.
