Hi,
I have a simple workflow. A user form has one text field called item and one number field called amount . When starting the Process I set the inital values.
In the externalTaskClient I want to catch these values. But the number field causes an error
String item = externalTask.getVariable(“item”); // THIS WORKS
Integer amount = (Integer) externalTask.getVariable(“amount”); // THIS DOESN’T
