Issue when debugging a process: [POP.002.0005] Unable to locate command: formFlowTaskNotify_ws

Dear all,

(I hope that this is the right forum to ask this)

Have anyone bumped on this error message?
[POP.002.0005] Unable to locate command: formFlowTaskNotify_ws

Below is the top of the stack trace message: [PRT.0101.9125] Service <snip>.Default:Approver1_InputMapService failed.
com.wm.util.BasisException: SOAPException( Server.generalException: [POP.002.0005] Unable to locate command: formFlowTaskNotify_ws; nested exception is:

I got this error when I was “process debugging” a freshly drawn process (laid out the steps, connected them, assigned the task types, and then debugged it).

This name, “formFlowTaskNotify”, does ring me a bell: I’ve played with the sample “Working with Task Work Flows (Form Flows)” [url][/url] quite a time ago, but I’m was not sure that it have anything with this. I looked the article again, but couldn’t find any place that any WS was set.

Besides this, I’m clueless.

Any idea will be appreciated.
