We are using Behaviors to make several fields required on some issuetypes in one project. We you move a ticket from one issuetype to another these required fields are not enforced. For example, issuetype A does not have the some of custom fields that issuetype B has. Some of these additional custom fields are required on issuetype B. When the issue is moved from type A to type B, the wizard does not give the option to define these additional fields, regardless if they are required on issuetype B or not. How do I fix this?
