               <props>
                    <prop key="engineId">activiti</prop>
                    <prop key="location">alfresco/workflow/first.bpmn20.xml</prop>
                    <prop key="mimetype">text/xml</prop>
                    <prop key="redeploy">false</prop>
                </props>
when i strat workflow in share am getting error like this.

Hi

Hi,

maybe it's the same issue like <a href="https://forums.alfresco.com/forum/developer-discussions/workflow/processes-doesnt-correctly-end-work...">here</a>. It could be a bug…

I hope this helps you further…
