In NetBeans I have an enterprise application that is composed of many NetBeans projects.
If I delete a JBoss Server (Under Tools | Servers), all of my projects are correctly displayed in red showing that they have no server associated with them. If I then re-add a server (for example when upgrading a version of JBoss), I have to go through each project manually and select "Resolve Missing Server Problem..." to add the new server to each project in turn.
If would be useful if you could resolve all missing server dependencies in one go, using the same server for each, rather than having to resolve one by one.
I've filed issue 175509 regarding this.
Cheers,
Dave.
