Calling signal methods on completed workflows

Community Support

What is the behavior when a signal method is called on a workflow that is already complete?
i assume the signal methods are supposed to be called to send data to a workflow that is in execution. But if the workflow is already complete, will the framework throw any exception?

Which SDK are you using (you can tag it when creating a thread on the forum).

In case you try to signal an already completed workflow from your client, the client call should receive the WorkflowNotFoundException in the Java SDK.

Hi,
a related question(Java SDK only):
if i try to create a workflow stub for an already completed workflow through
WorkflowClient.newWorkflowStub(Class workflowInterface, String workflowId);
function call, will we get the same WorkflowNotFoundException exception?

Stub creation doesn’t check if an ID is valid. When you call a signal or query method on that stub, you can potentially get WorkflowNotFoundException.

Thanks for the clarification Maxim!
