Description

We have implemented a centralized error system where each error can be:

• either marked with the zobject row ID to allow the components to grab any errors that have been detected, or
• a generic error shown page-wide, which should be shown in the Publish component as part of the publishing flow

Observed behavior:

• Errors are currently not being shown properly or being shared among components.
• Errors from failed implementation are being shown in the About widget

Expected behavior (Acceptance criteria):

We should

• review all the new Default View components and make sure that all getError methods are being called with the right ids
• review handling of general page-wide errors and make sure that the are reported in the Publish Dialog
• review the widget About and make sure that only relevant errors are being shown in its fields
