Hi everyone!  
Big fan of flowable and the workflow with it!

I am using Verison 6.7.2 and want to integrate sending an Event to RabbitMQ via EventRegistry.

For this i use a SendEvent Task and want it to be executed synchronously.  
Disabling the “async” Checkbox does not work though.

I have studied the Code of flowable-engine and have noticed that it checks

sendEventServiceTask.isSendSynchronously()

This parameter is always false, regardless of the async property  
However i could not find out where in the XML i can set this property.

The XML Definition under flowable-bpmn-extensions.xsd does not have a sendsynchronously property.

Hope someone can help me out here!

Thanks in advance  
Rene

Nevermind, found it out.  
It has to be declared as extensionElement

```auto
 <serviceTask flowable:type="send-event">
        <extensionElements>
 <flowable:sendSynchronously><![CDATA[true]]></flowable:sendSynchronously>

```
