signalEventReceived not working during debugging

[apavlenk0]

Hi,
I was faced with strange issue.
I use intermediateCatchEvent and try to test it

String processInstanceId = runtimeService.createExecutionQuery()
                .processInstanceBusinessKey("businessKey").singleResult().getProcessInstanceId();

Execution execution = workflowRuntimeService.createExecutionQuery()
                .processInstanceId(processInstanceId)
                .signalEventSubscriptionName("subscriptionName")
                .singleResult();

runtimeService.signalEventReceived("subscriptionName", execution.getId());
‍‍‍‍‍‍‍‍‍‍‍

this code works but if I stop execution (using debugger) and then start it again signal wouldn't work.

How does signalEventReceived method works? Is there any restriction for using it?

What do you mean with "signal wouldn't work". What happens?
Could you include your process definition?

Best regards,

Hi, thank you for your reply

I cannot include all process definition, here is part with signal

<code>
<definitions id="definitions"
             targetNamespace="http://activiti.org/bpmn20"
             xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xmlns:activiti="http://activiti.org/bpmn">

    <signal id="signal" name="subscriptionName" />

    <process id="process1" name="process1">
…

        <serviceTask id="st1" name="st1" activiti:expression="#{…}" />
        <sequenceFlow sourceRef="st1" targetRef="signal1"/>

        <intermediateCatchEvent id="signal1">
            <signalEventDefinition signalRef="signal" />
        </intermediateCatchEvent>
        <sequenceFlow sourceRef="signal1" targetRef="st2"/>

        <serviceTask id="st2" name="st2" activiti:expression="#{…}" />
        <sequenceFlow sourceRef="st2" targetRef="finished" />

        <endEvent id="finished"/>
    </process>

</definitions>
</code>

When I say "signal wouldn't work" I mean that serviceTask (id="st2") wouldn't executed

Question is no longer relevant,
found problem in

<code>
<serviceTask id="st2" name="st2" activiti:expression="#{…}" />
</code>

method that was called in activiti:expression contained an error.
