[vbox-dev] bug - TRANSIENT guest property can't get deleted?

Thanks for the fix. I confirmed that it fixed the issue of transient property becoming permanent after delete.
But still have some problems deleting guest properties, the xml file still shows some temp guest property after value is set to NULL. The good thing is that they won't get saved to the xml after vm is shutdown.

This is fixed in the 3.2 branch as follows:

Index: src/VBox/Main/MachineImpl.cpp
--- src/VBox/Main/MachineImpl.cpp
+++ src/VBox/Main/MachineImpl.cpp
@@ -10374,5 +10374,5 @@
-        if (aValue != NULL)
+        if (aValue != NULL && aValue[0] != '\0')
             HWData::GuestProperty property = { aName, aValue, aTimestamp, fFlags };

It is not yet fixed in trunk, as we want to do a more invasive fix
involving a proper delete API.
