BootStrap MultiSelect Widget is not working for Retrieve Type Microflow
When I select Retrieve Type Microflow, to get the list from microflow in BootStrap MultiSelect Widget, Its not working, it doesnot show values in the dropdown. The association is one to many. It works for Retrieve Type XPath but not for Retrieve Type Microflow
Does the selected Data source microflow return the list?
Try debugging the Data source microflow and see if the list you return is filled with items.
If not, then no data is shown in the dropdown either.
If you get a list, but the dropdown is still empty, the problem could be with entity access.
