[magnolia-dev] [JIRA] (MGNLUI-1800) Errors in apps breaks admincentral

Fri, 28 Jun 2013 02:45:07 -0700

Issue Type: Bug Bug
Affects Versions: 5.0
Assignee: Unassigned
Components: app framework
Created: 28/Jun/13 11:34 AM
Description:

When an app encounters a problem, either because of a configuration error, such as starting an app that is not correctly configured or when it throws an exception because of a programming error, admincentral breaks because it gets stalled in app loading mode.

We need a plan for how we deal with this, either just close the app and go back to app launcher, or insert a view that informs the user about the error.

Here's two scenarios in which this happens:

Launching an app that doesn't have any sub apps
