We use a Project User Input that was designed with the Choice List option. The list has over 400 corridor names in it, which were entered by simply pasting the list into batch edit box.
For the users on the app side, when a project capture is started, the prompt for the Project User Input (Corridor) comes up. Previously, the Search feature worked wonderfully, and was crucial to our users finding the correct code value among the 400+ choices. Now the Project User Input value Search is non-functional. This is devastating to the usability of the tool, and to our likability as the tool designers.
I have tried creating a brand new project and brand new sample choice list for a Project User Input in order to double-check this Search functionality. It still didn't work.
