I would have thought that even in the second scenraio, when the instance is not sitting in a &lt;Wait&gt; state, the client code should not get an error and instead the instance should get notified as soon as the instance arrives in the 'Intermediate Catch Message Event' step.</SPAN><BR /><BR /><SPAN> Surely, this request should get QUEUED and the instance should be notified when it arrives at the &lt;Wait&gt; step.</SPAN><BR /></BODY></HTML> Mon, 29 Feb 2016 17:21:43 GMT samsmith 2016-02-29T17:21:43Z Message Notification https://connect.hyland.com/t5/alfresco-archive/message-notification/m-p/219275#M172405 Hi,I have got a question on the following scenario:Lets say that I have a BPM process that that has 2 steps:'Human Task' followed by a 'Intermediate Catch Message Event'.The below&nbsp; code works perfectly fine if I notify the instance that&nbsp; is already sitting in a 'Intermediate Catch Message Event'.xxx Mon, 29 Feb 2016 17:21:43 GMT https://connect.hyland.com/t5/alfresco-archive/message-notification/m-p/219275#M172405 samsmith 2016-02-29T17:21:43Z Re: Message Notification https://connect.hyland.com/t5/alfresco-archive/message-notification/m-p/219276#M172406 <HTML><HEAD></HEAD><BODY><SPAN>Hi Sam,</SPAN><BR /><BR /><BLOCKQUOTE class="jive-quote">Is this an expected behaviour?</BLOCKQUOTE><SPAN>yes</SPAN><BR /><BR /><SPAN>You can implement queueing by yourself if you want to have something like that.
