I am facing an issue with regards to the hidden parameter in IC Web Client Advanced Search UI. In our search application we have a search criteria called BP GUID, but showing a GUID in the UI is not user friendly as a 32 character long string. Is there a way to show this GUIDu2019s associated numeric ID (sort of a mask) in the UI, but in the selection parameter collection that is passed to the backend Search API still keeps the GUID value? Or alternatively, is there a way to add a hidden selection parameter not showing it to the UI but passed to the backend? I searched the UI framework Wiki but didnu2019t find anything relevant. Hope someone could help here....
