timesheet dashboard does not work
In Tryton 4.0, the dashboard provided by the timesheet module does not work.
With the GTK client, the chart is shown just for less than a second and then disappears. Selecting any project (including those with timesheet lines assigned) does not show any charts.
With sao, the chart is shown when the dashboard is shown but then selecting any project also makes the chart disappear and is no longer updated.
