I've Form with 2 list lookups linked as cascading dropdowns. When accessing the form via the intranet, the 2nd dropdown works properly. However, if an external contact with a company account access the form via the internet portal, the 2nd dropdown is stuck in the "Loading..." mode. Selecting a value in the 1st dropdown does not seem to affect the 2nd dropdown.
Does anyone has an idea what may cause this? And how to resolve this?
