I'm developing a custom control for Task/Bug Work Items so I can query for shelvesets related to the Work Item.
First off I tested a simple control with nothing but a listbox with an Item. When I preview the layout form in the Process Editor in VS2010, it shows up alright, but when I create a new Task, upon loading it shows a message instead of my control:
"Form Rendering Failed: Object reference not set to an instance of an object."
What I really like about these error messages is that they're always crystal clear... I'm clueless, what could be causing this behavior?
Thanks in advance!
