<div class="jive-rendered-content"><p>Hi community,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am digging into jBPM5 and I have a question dealing with User Task Assignment. I went through several posts about something similar but can not really find an answer to my question...</p><p>The simple and usual way with User Taks is to assign fixed actor(s) or group(s) but if my User Task assignment relies on process data or even event?</p><p>I know you can do something like what is done with Evaluation.bpmn process that is to say use a #{employee} as potentionalOwner and set value of employee variable at process start.</p><p>What would be the solution if I want to assign a User Task to an actor dynamically and based a specific algorithm not just an input field value. Some questions about this situation to get best practise or orientation from community :</p><ol><li style="text-align: start;">Is the use of a variable as potential owner (e.g.  #{employee}) the "good" way to handle this kind of situation?<ul><li style="text-align: start;">is possible to set it as group id?</li><li style="text-align: start;">other way or solution to set dynamically my actor or group ID? Can a User Task actor or group id be left blank and assigned programmatically? => I've read somewhere that when a user Task is reached at process runtime it must assigned to an actor or group at least Administrator. => "By default, jBPM registers a special user with userId "Administrator" as the administrator of each task. You should therefor make sure that you always define at least a user "Adminstrator" when registering the list of valid users at the task service." This sentence let me think that no specific actor can be set when modeling a BPMN process? Is it correct?</li></ul></li><li style="text-align: start;">Where do I have to plug my specific User Task assignment algorithm? Can it be for instance in an On-Entry script of the User Task or is it too late? If too late is the answer where can I plug it (I hope there is no need to model a specific Task (Service Task) before the User Task?</li><li style="text-align: start;">Is it possible to make a User Task assignment with a Drools rule?</li><li style="text-align: start;">Are there any example available showing these kind of situation?</li></ol><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="text-align: start;">This makes quite a lot of questions but any help or advices would be appreciated <span> ;) </span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="text-align: start;">Kind Regards</p></div>
