topic Tracking execution tokens and transitions in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/tracking-execution-tokens-and-transitions/m-p/47525#M26983 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I am currently working on the use case where I need to retreive process variables based on information about previously executed activities. I want to retreive only those process variables that have been changed by "previous" activities in the control flow but not those which were created/changed by activities in parallel control flows. I tried to put execution listeners on transitions, but the problem is that I could not find a way to retreive information from Activiti about which execution will be used to take the outgoing transition. The code snippet from the ExecutionImpl shows that this information is never made available.</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // first create the concurrent executions<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; while (!transitions.isEmpty()) {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PvmTransition outgoingTransition = transitions.remove(0);<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ExecutionImpl outgoingExecution = null;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (recyclableExecutions.isEmpty()) {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution = concurrentRoot.createExecution();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log.fine("new "+outgoingExecution+" created to take transition "+outgoingTransition);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; } else {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution = (ExecutionImpl) recyclableExecutions.remove(0);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log.fine("recycled "+outgoingExecution+" to take transition "+outgoingTransition);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution.setActive(true);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution.setScope(false);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution.setConcurrent(true);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecutions.add(new OutgoingExecution(outgoingExecution, outgoingTransition, true));<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // prune the executions that are not recycled <BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (ActivityExecution prunedExecution: recyclableExecutions) {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; log.fine("pruning execution "+prunedExecution);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; prunedExecution.end();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // then launch all the concurrent executions<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (OutgoingExecution outgoingExecution: outgoingExecutions) {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outgoingExecution.take();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><SPAN>So my question: is there any way to track back execution transitions to get a path/trace of the execution token?</SPAN></BODY></HTML> Wed, 10 Aug 2011 11:45:36 GMT danosaur 2011-08-10T11:45:36Z Tracking execution tokens and transitions https://connect.hyland.com/t5/alfresco-archive/tracking-execution-tokens-and-transitions/m-p/47525#M26983 Hi,I am currently working on the use case where I need to retreive process variables based on information about previously executed activities.

Can you please point me a way to do this using history queries? I have set the history level to full, but looking at the act_hi_* tables I can not figure out how execution tree can be restored from history since entries in these tables do not store information about transitions and execution hierarchy.</SPAN></BODY></HTML> Wed, 10 Aug 2011 15:15:21 GMT https://connect.hyland.com/t5/alfresco-archive/tracking-execution-tokens-and-transitions/m-p/47527#M26985 danosaur 2011-08-10T15:15:21Z
