I'm trying to use a data driven checkbox group, but having trouble with the data source.
If I hard code the data source in the form, the checkbox group behaves as expected to display a check box for each data item.
If I populate the data source using form prefill, the checkbox group does not display any details.
I've examined the prefill service and the data is present in the xmlDoc, but using developer tools in the browser, it appears that there is no data in the data source.
Other data fields on the form are prefilled correctly; it is only the data source for the checkbox group that is not populated correctly.
How can I populate a data field as data source for a data driven checkbox group?
Maybe by invoking a dynamic service on the page load event where that particular field is located?
