workflow faulting
Hi,
For some reason, on one particular machine we run workflow on, i cant get anything to "stick" in workflow. I'm able to get an instance into workflow, but shortly after this, i get the below tracking detail which shows that the workflow is faulting. How do i find out exactly what's going on? thanks.
Symyx.Workflow.StateMachineTrackingChannel [(null)] - Tracking detail: Activity: 'SymyxBasicWorkflow' Faulting
Symyx.Workflow.StateMachineTrackingChannel [(null)] - Tracking detail: Activity: 'Start' Canceling
Symyx.Workflow.StateMachineTrackingChannel [(null)] - Tracking detail: Activity: 'Start' Closed
Symyx.Workflow.StateMachineTrackingChannel [(null)] - Tracking detail: Activity: 'SymyxBasicWorkflow' Closed
Symyx.Workflow.StateMachineTrackingChannel [(null)] - Tracking detail: **** Workflow Instance Completed or Terminated ****
you can do multiple things here
1. Handle WorkflowTerminated event on the WorkflowRuntime in the host. WorkflowTerminatedEventArgs property of the handler will contain exception details which caused the workflow to terminate.
2. Enable tracing. This will dump detailed information about execution states of the workflow and the exception information in the log file. Tracing can be enaled by adding following in the app.config
<configuration>
<system.diagnostics>
<switches>
<add name="System.Workflow LogToTraceListeners" value="1" />
<add name="System.Workflow.Runtime.Hosting" value="All" />
<add name="System.Workflow.Runtime" value="All" />
<add name="System.Workflow.Runtime.Tracking" value="All" />
<add name="System.Workflow.Activities" value="All" />
</switches>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="customListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="WFTrace.log" />
</listeners>
</trace>
</system.diagnostics>
</configuration>
3. Debug the workflow using VS.
