A number of conditions aren't error checked at all. Occasionally timeouts to the EC2 api throw uncaught exceptions that lead to stacktraces in MediaWiki. Also, other conditions, such as bad replies or API failures simply go unchecked resulting in incorrect display, or creation of LDAP objects when Nova objects haven't been properly created.
All API errors should be checked, and proper error messages should be displayed.
Version: unspecified
Severity: normal
API timeouts occasionally don't cause exceptions either, instead no data is returned, leading to resource lists that are empty. An error message should be shown to the user in this situation.
We (the labs team) plan to add no more new features / do any non-critical work on OpenStackManager - switch to Horizon is under way :) Other users of OpenStack are also advised to *not* use OSM, if for some reason they think it is a good idea - in fact even we don't have an exact test setup left. So I'm on a closing spree, closing all things directly OSM related. Please re-open with different projects added if you think this would still be an issue on Horizon. Thanks!
