Usage of Lightweight Edges and Regular Edges

ghost commented 7 years ago

OrientDB Version: 2.2.22

Java Version: 1.8.0_144

OS: Windows

I have existing databases with lightweight edges. At some point I switched to regular edges. So it seems I have existing lightweight edges...

The database works in the application but when I open the Orient Graph Editor I receive the following exception when i select one of the vertices in the editor and a lot of edges are missing.

$ANSI{green {db=database}} Exception `51818281` in storage `database`

Is there a recommended migration procedure that I missed to perform?

Hi @loers

there is not migration procedure. lightweight are automatically if necessary.

This seems related Graph editor that does not handle well lightweight

ghost commented 6 years ago

Okay thats good. So it's a bug with the graph editor? Its pretty inconvinient not to be able to check the graph in the editor. Can this be a version problem? I used the current version of the graph editor.
