I have one list that contains a set of releases and statuses. As part of that list I have a computed column that only returns releases that are in an "Open" status.
I have another list that contains a lookup column that is not required, but points to the computed column above. (i.e. when a problem is entered, I only want a user to select releases that are "opened", not see a list of ALL releases which can get long.)
This works fine.
However, if I accidently pick a release for a new issue and save it. There is no way for me to remove that release. Only thing SharePoint does is show me the list of current releases that are opened, but there is no "x" or anything that I can remove my previously selected release. The column in the issues list is marked not required, so why is SharePoint not letting me remove the value?
