Rob's search & script combo would produce a focused window showing only the flagged, active projects in your data, without showing any flagged actions that are part of unflagged projects. You could then create a perspective showing the contents of that window and update it when flagging or unflagging projects. It's unfortunate that it runs into an error in your setup, but perhaps if you supply the details of exactly which version of OF you are running, and the system configuration, we can try to figure out what is going on.

That said, allow me to try to convince you that you don't need the feature you requested :-)

The natural way to work, I think, would be to look at all of your flagged actions before looking at the actions without flags. Let us suppose that you have a project to write a report on some matter, and another to prepare for a meeting, both of which are urgent, so you have flagged the two projects. You also have a need to contact a colleague today about some other matter, but only that task is urgent, not the whole project to which it belongs, so you flagged the action.

How to proceed? Flip over to context mode, group your display by project, sort by due, show available actions, flagged actions only (or perhaps flagged and due soon), any duration. If you only had a few flagged actions outside of the flagged projects, you can probably get right to work from the list as is. If you had a lot of flagged actions outside of the flagged projects, and you want to ignore them while you work the flagged projects, use View->Collapse All to close all of the groups, then open just the ones for those projects on which you wish to concentrate.

Is there anything about what you want to achieve that isn't handled by doing that? Or even simply sorting project mode by flagged, which puts all of the flagged projects at the top of the window, and everything else below, making it easy to replicate the results of Rob's script by hand by selecting the flagged projects and pressing the focus button?
