Thank you for writing back.
The DataForm is always related to a single business object and there is no option to have an editor in the data form that is not related to a property from your business object. The options that you have to populate a data form are:
1) through an instance of a class that represents your business object
2) through json string
If your business object needs to be updated runtime, you still need to use one of the above mentioned approaches. Here's what to do for each of them:
1) you can create the new class at runtime as demonstrated here
and pass an instance of it to the data form
2) you can create a json
from the information that you have and pass the json to the data form
I hope this information helps.
