Hello Gerd, the grid is a grid. It is not a form (although it may contain forms) therefore it does not have a grid.errors. Embedding into a form does not solve the problem.
Yet you can check if the grid contains a form and whet the errors for that form are: if grid.create_form and grid.create_form.errors: .... if grid.update_form and grid.update_form.errors: ....
