I am trying to stop asynchronous flow in mule by using muleContext.registry.lookupFlowConstruct('').stop() command in groovy script, but even after it still triggering the flow.I want stop it abruptly.
you can try
eventContext.setStopFurtherProcessing(true)
or
<expression-component>
app.registry.yourflowName.stop();
</expression-component>
if you are looking to stop the messages to go to your flow, you can also use filters.
