create of BPMN xml failed in activiti5.12

[wysh]

Hi,
i am now working with activiti 5.12
table driven definition is used to create simple workflow for my project …but when i am trying to export or deploy model, error occured and error message is shown as "create of BPMN xml failed null"
what may be the reason for that..?

We're working on resolving the issue with the table-driven editor… As you know, activiti-explorer is a testing-ground and some experimental things can have some issues. We're creating a new distribution this week.

The source-code is here: https://github.com/Activiti/Activiti

Hi,
now users need to be predefined in the xml…is there any way to change users dynamically for a workflow without creating new bpmn xml file…?

You can use a process-variable to determine the assignee, e.g.: activiti:assignee="${selectedPerson}". When starting your process, you can add the  "selectedPerson" variable to the passed-in map. Or you can use form-property as well to pass in the value of the "selectedPerson"…
