Hi Vladimir, yes we are improving the UI of the designer to make it more user-friendly, especially for user inputs such as process variables and data input/output associations.
Currently, to define process variables, in the BPMN-Diagram properties section you can defined them in the Variable Definitions input field with the following pattern:
so for example you could have:
If you do not specify a type, it will default to Object type.
For user tasks, you have couple of property fields to look at:
DataInputSet: comma-separated definition of data inputs of the task, for example: a,b
DataOutputSet: comma-separated definition of data outputs of the task, for example: j,k
Assignments: define the input/output assignments and associations here, for example if you define process variables x,y and let's say usertask data input a and b, and task data output c you could have:
in which case process var x will be mapped to the data input a, b will be assigned to string Hello, and output c will be mapped to proces var y.
You can also do bi-directional associations, for example:
where x is mapped to a and then a is mapped back out to the process variable x. Note that in this scenario you have to define a as in both the usertask DataInputSet and DataOutputSet.
Hope this helps.
thank you very much. It works.
