[jBPM] - Re: Using jBPM as state machine engine - is it a good idea?

To view the discussion, visit: https://community.jboss.org/message/778267#778267 -------------------------------------------------------------- I would say you could do this by combining power of jBPM and drools. First of all, I believe that traditional process definition would not fit your needs but ad hoc processes are in my opinion excellent choice here. See some details about ad hoc processes http://docs.jboss.org/jbpm/v5.3/userguide/ch.flexiple-processes.html here. Just one important comment is that you would not rely on process instance state as it's internal information for the engine and cannot be altered based on business data but rather use process variable that can be easily modified by process activities and rules. Generally it would work like this: - start ad hoc process which will not make any activity running yet - signal given activity or execute rules that will decide what activity should be signaled - at any point a decision needs to be taken a business rule task should be executed that will evaluate what needs to be done: - set process variable according to current state of the process - signal another activity to continue processing HTH -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/778267#778267] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Is it possible to create task with multiple groupId constraint?

by Thomas Setiabudi

Thomas Setiabudi [https://community.jboss.org/people/thomas.setiabudi] created the discussion "Is it possible to create task with multiple groupId constraint?" To view the discussion, visit: https://community.jboss.org/message/778524#778524 -------------------------------------------------------------- Hi, Lets say we have two user grouping tables: 1. UserDepartment -> this table maps user with department like Accounting, Human Resource, or Marketing. sample record would be: (thomas, Accounting) 2. UserJobTitle -> this table maps user with job title like staff, supervisor, or manager. sample record would be: (thomas, Supervisor) Now, we have a human task in our process, the human task can be done by any Supervisor in Accounting department. How do we do it? Based on IRC chat with Maciej: By Default Group Assignment is based on OR operator The only workaround that I can use for now is to manipulate the group name, concatenate it to one single String like this: "Accounting|Supervisor" That works, but it adds more complication as we have more and more group combination, lets say instead of those two groups, we have three more tables. Any idea? Is it a good candidate to ask a feature request for this requirement? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/778524#778524] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

However that's just an idea that could not be applicable for your scenario. Any way, could you provide an example of process you use for this so we could take a closer look at it and maybe suggest some other approach.
