I am trying to create a custom bulk action for a custom grid in the admin area. I followed the description in https://docs.sylius.com/en/1.3/components_and_bundles/bundles/SyliusGridBundle/custom_bulk_action.html
All works fine except the Controller does not receive the selected ids.
At the end of the docs mentioned above is written: "Let’s assume that you already have a route for exporting by injecting ids, " and I have no idea how this is supposed to be. I tried several options but without success.
Has someone a complete example of a custom bulk action or can someone indicate an example in the Sylius source code that is not the default bulk action DELETE?
Thank you very much in advance.
