When dropdown value is changed, Using the Change the Rest URL functionality - Second dropdown Rest URL is changed to something like this - concat(URL, Listname?, "$filter=(Company_Value%20eq%20'", ., "') and (EnvironmentValue%20eq%20'", txtEnvironment, "')&$select=Vendor_Type_Name,Vendor_Type_Value&$orderby=Vendor_Type_Name") and Data connection is queried again... Form has more than 400 fields and with multiple rules on each field.. If I had to change the data connections to normal list data connections, it will become a huge risk. I did try with disabling the anonymous access for the SharePoint web application in IIS, but it did not resolve the issue.https://www.infopathdev.com:443/forums/thread/123492.aspxTue, 29 Sep 2020 14:55:01 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:123492Hilary Stoupa0https://www.infopathdev.com:443/forums/thread/123492.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=123492Is there a complex filter here that requires you to use REST instead of a normal list connection with query fields?

My InfoPath form has two dropdowns - Dropdown1 for Company and Dropdown2 for Vendor. This is a cascaded dropdown functionality. Selected value from dropdown1 is used to Change the Rest URL call for second dropdown data connection (adding the filter in Rest web service URL with selected dropdown1 value) and then Query using a data connection is run again to populate dropdown2 values. Form behavior - data is loaded fine on form load in dropdown1, when a value is selected in dropdown1, it shows sending data to the server but nothing happens and dropdown1 resets. If the dropdown value1 is selected again, then following error shows up - Critical Error A Microsoft SharePoint Server State Service error occurred while processing your request. For more information, contact your server farm administrator. Click Start over to load a new copy of the form. If this error persists, contact the support team for the Web site.
