A manual task is a an automated step, that does literally nothing.

It is used by process modelers to model that something is done outside of the BPM engine, and therefore it acts as a 'passthrough' activity.

I deployed the process from the thread starter and got the following error (with usertask instead of manualtask; activiti5.beta1):

Any ideas?

Could you paste the process so I can try it out?

Re: Error with ManualTask and boundaryEvent

It's the one from above:

<process id="sampleTimer" name="sampleTimer">
   <startEvent id="start" />
     <sequenceFlow sourceRef="start" targetRef="javaService" />
        
       <serviceTask id="javaService" name="javaService" activiti:class="main.java.Guardian" />
      <sequenceFlow sourceRef="javaService" targetRef="waitTask" />
           
       <userTask id="waitTask" name="waitTask" />
       <sequenceFlow sourceRef="waitTask" targetRef="theEnd" />
       
       <boundaryEvent id="oneTimer" cancelActivity="true" attachedToRef="waitTask">
      <timerEventDefinition>
      <timeDuration>PT10S</timeDuration>
      </timerEventDefinition>
   </boundaryEvent>  

       <sequenceFlow sourceRef="oneTimer" targetRef="javaService" />
       <endEvent id="theEnd" />
</process>
