cant delete/cancel workflow instance

heck — Tue, 24 Jan 2012 13:09:55 GMT

Hi there,we are using alfresco community edition V.4.0bI wanted to delete all workflow instances (assuming this will delete all tasks as well).So i wrote a webscript:var wfDefs = workflow.getAllDefinitions();for (i in wfDefs) { var wfDef = wfDefs[i] logger.error("Def:" + wfDef.id); var wfInsts

Is it a requirement to use JavaScript to do this? If not, have you tried using the workflow console?

I think Jeffs suggestion to use the wf console is "the right thing to do here TM".

However, regarding your question, beware that the javascript logger object only has the method logger.log("…").
There is no .debug or .fatal as it is in javas log4j loggers.

Hi,
Thanks a lot for your replies.

Yes, i am familiar with the workflow console. But i really intended to do this programmatically…

Regarding the log object:
i am always using e.g

logger.error("Resolving task:" + taskId);‍

with the expected result.
just FYI.

Thanks anyways.

Update again:

As u know, using wfInst.delete() doesnt work becuase delete is a reserved word in javascript.
if i instead use wfInst.cancel(), i get

JavaException: org.alfresco.scripts.ScriptException: 012120470 Failed to execute supplied script: 012120469 TypeError: Cannot find function fatal. (AlfrescoJS#2)

using this code


function main() {
   var wfDefs = workflow.getAllDefinitions();
   for (i in wfDefs) {
      var wfDef = wfDefs[i]
      logger.error("Def:" + wfDef.id);
      var wfInsts = wfDef.activeInstances;
      for (j in wfInsts) {
         wfInst = wfInsts[j];
         logger.error("   Inst:" + wfInst.id);
         wfInst.cancel();
      }
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

but if i comment out the cancel(), like this:


function main() {
   var wfDefs = workflow.getAllDefinitions();
   for (i in wfDefs) {
      var wfDef = wfDefs[i]
      logger.error("Def:" + wfDef.id);
      var wfInsts = wfDef.activeInstances;
      for (j in wfInsts) {
         wfInst = wfInsts[j];
         logger.error("   Inst:" + wfInst.id);
         //wfInst.cancel();
      }
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

the code runs and does what it s expected to do.

So, i can confirm, it seems like the "cant find fatal" thing hassth. to do with the cancel() method.

This is just a confirmation of observations.

Thanks for any reply.

Best Regards

but after commenting that line. Are you able to delete the workflows?

If what you are trying to do is work around the "delete is a reserved word" problem, try using this syntax instead:

wfInst['delete']();
