I'm using Odoo8 and added some custom search results for sale orders to my dashboard (by the standard functionality). When I open the dashboard I can see the table header for my filtered list but no data are displayed. As soon as I click on a column in the table header the information are being loaded and displayed.

Why aren't the records loaded directly when I open the dashboard?

To reproduce go to Sale -> Sale orders, filter by customer "foobar" and add this to a dashboard. Then open the dashboard : Menu -> Reporting -> Dashboards -> My Dashboard.
In my case I can see the panel for my filtered element and the table headers but not data.

The fields_view_get is properly executed to show the table but it seems there is the search_read missing to load the data/records. Only by clicking the table header the search_read is executed.

Does anybody can confirm this behaviour or may have an idea how to fix this?
