I am also not happy about this behaviour. But Radim once told me that
this is not possible, that v.externaled layers can be displayed in QGIS.

I _really_ like to see this happen in the near future, but sadly I am
not the one who can implement it...

Yes, within GRASS everything works well.

Perhaps someone could add some hints why this is not possible to
implement (perhaps rocket science?!), because the user-demand for such
a feature is quite high (at least 2 :-)

Perhaps we should include the qgis-devs since
v.external works fine in GRASS AFAIK?

I know, not really an answer for you, just another interested user...

Cheers
