I’m developing a customization in the Data Collection - Handheld - Material Handling - Issue Material screen. The purpose of the customization is to scan a bar code into a custom text box and populate the Job, Asm, and Mtl textboxes using the Leave event of the custom text box. When I scan the bar code, I get a null reference exception - there’s nothing in the data view. Any ideas as to why the data view would be null, or how to make this customization work?
