After the conversion of the graph and pivot views done in https://github.com/odoo/odoo/pull/73311, it was no more possible to open the forecast_graph and forecast_pivot views. This is due to the fact that the new View component cannot manage a legacy view: every extension of a converted view must be converted. We thus convert forecast_graph and forecast_pivot. closes odoo/odoo#76793 X-original-commit: ff28db335fa77dadc3198e754f1e0649811fba7b Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
