As admin user, I've created in Admin - System - Volumes new Volume type. Afterwards I've click on 'View Extra Specs' by the row with this volume type. It raises modal dialogue with list of existing key-value and also table-scoped buttons Create and Delete Extra Specs.
If I click to Create, Edit or Delete Extra Specs, I'm finally always redirected to:
http://devstack/dashboard/admin/volumes/volume_types/b6936d96-e8a0-4dc4-a60b-9079aa10a6f1/extras/, so I'm not in the dialogue anymore (with list of volume types in background).
The whole dialogue with action table seems identically as same as click to 'View Extra Specs' on the row with volume type again.
I would propose to have just one consistent way how Extra Specs should be handled, it's quite confusing at this moment.
a) as modal dialogue, would be probably more difficult to implement due to nested dialogues.
b) as separate page, so by URL like: ...volume_types/uuid-of-vt/extras
I cannot access the link. Could you please provide screenshot?
