Generating a Business Key

The following example shows how you can generate a business key using Javascript:

<form role="form">
  <script cam-script type="text/form-script">

    camForm.on('submit', function() {
      camForm.businessKey = 'some-generated-value';
    });

  </script>

</form>

As you can see, you can set the businessKey variable on the camForm object. The value you set will be submitted in the start process instance request. Note that the business key can only be set when a process instance is started, not when completing a task.
