Here's what I would do:
In OnDetectTargetMsiPackage gather the productcode and check the installed
state of all of the patches on that product. Store that in memory.
In OnPlanTargetMsiPackage I would prevent an uninstall of patch 2 for the
indicated productcode if detect indicated that patch 3 was present (and I
hadn't already received an OnPlanTargetMsiPackage for removal of patch 3 for
that same productcode).
If the OnPlan* callbacks aren't ordered that way then I would rerun the plan in
OnPlanComplete if needed.
Then again I'm not yet a burn expert. Some of the others on the list may have a
better idea.
Please report back if this works or not.
