Mosaic reloads publications from Symplectic every two days. If Symplectic updates overnight, the changes should be displayed in the Publications listing widget the following day.
If at any point you do notice a discrepancy between a record in Symplectic and the record as it appears in the Publications listing, you can force the listing to Sync with Symplectic using the button at the bottom of the widget editing screen:
If you still see discrepancies between Symplectic records and what appears in the widget, please contact the Mosaic team, giving details of which publications should or should not be appearing.
Hiding a Symplectic record
If a publication is marked as 'hidden' in Symplectic Elements, it should not display in the Publications listing widget. If you set up a Publications listing widget and notice records which should be 'hidden' displaying in it, please contact the Mosaic team so we can look into it.
When there are discrepancies between what appears in the Publications listing widget and what appears on the 'More' page this usually indicates that one or both have been cached in an out-of-date state.
Because the 'More' page is not an editable Mosaic page, it is unfortunately hard for site editors to update it if it is cached in an incorrect state. A workaround for this is to change the filter options (e.g. set or un-set the 'Filters section expanded on More page by default' option) and re-save the page; because these options are encoded in the URL for the More page, changing the options changes the URL, so users will be directed to the new uncached version. The old version will expire from the cache after 7 days, at which point you can change the filter options back if you want.
If the listing in the widget is not updating there are more ways to try to re-sync this -- you can use the 'refresh live page' button to clear the page from the cache, and you can use the 'sync with Symplectic' button from the widget editing form to reload the feed of publications from Symplectic.
