How to set a task due date in jBPM Designer

pschaefer Mar 20, 2015 8:55 AM

Hello,

is it possible to set the due date of a task in jBPM Designer like in the Activiti Modeler. I haven't found any entry for that issue. The only thing I have found is to set a notification, but that is not our use case.

The value of the due date is saved in the column EXPIRATIONTIME of the table TASK in the jBPM database. In the jBPM API I have found the method setExpirationtime. But you can only use it after a task instance is created.

The question: Is it possible to define a task due date in the process definition? Many thanks!

Human Task Handler has a input parameter called DueDate which is not listed in UI. However, you can treat it like any other task input variable. So what needs to be done.

Create task input variable called "DueDate":String
Create process variable called "p_DueDate":String
Do the variable mapping between these two.

Now, when you set the p_DueDate with some value, it will be mapped into DueDate attribute, and this attribute will be propagated in the Task List UI and therefore, available for filtering..etc. jBPM uses JODA time internally, and you need to use ISODateTime. Method dateTimeNoMillis() is used during the parsing process and it accepts following format:

yyyy-MM-ddTHH:mm:ssZZ (Ex. 2015-04-20T15:15:30Z

Hey Abhijit,

I have another question about that issue. Is it possible to define a default value for a task due date in the BPMN 2.0 model? Through the jBPM Designer or by editing the bpmn xml file?
I have not found any possibility to set a default value for a process value.

Hi,
We cant set default value of variable in process definition.But you can use one script task at the start of the process, which will set values for process variable.
share your thoughts on this approach.

Hey Abhijit,

thank you for your advice, it works! The only problem I have is, that I want to know which due date has set a value before process instantiation. For that issue I haven't found any solution.
In Activiti I was able to parse the BPMN file and see which variable is already set.

Hi,
I dont think we can check due date before starting process instance. The only way I can see is parsing BPMN process.
