Comment:

 In QGIS each feature needs to have a unique id (by which the feature can
 be retrieved, deleted updated etc.).   Filtering by 'test1' probably gives
 you a unique value and therefore makes the view insertable.

 As workaround you could probably combine the gids of polygon and line to
 produce a unique key.
