You may receive an "HwsServiceSoapException" exception error message when you call the GetActivityFlowInfo method immediately after you add an activation block to an activity flow in BizTalk Server 2004 (888752)


The information in this article applies to:

  • Microsoft BizTalk Server 2004 Enterprise Edition
  • Microsoft BizTalk Server 2004 Standard Edition
  • Microsoft BizTalk Server 2004 Partner Edition
  • Microsoft BizTalk Server 2004 Developer Edition

SYMPTOMS

In Microsoft BizTalk Server 2004, when you call the Activity Model Designer API GetActivityFlowInfo method to obtain Human Workflow Services (HWS) activity flow information, you may receive an HwsServiceSoapException exception error message.

Typically, this problem occurs after you add an activation block to an activity flow that contains more than one step and then you immediately call the GetActivityFlowInfo method.

CAUSE

This problem occurs when the tracking information is not available because of a latency issue. Therefore, when you call the GetActivityFlowInfo method immediately after you add the activation block, an exception is returned because the activity flow information is not yet available.

WORKAROUND

To work around this problem, you must wait for a while after you add the activation block and before you call the GetActivityFlowInfo method.
