Fix over this one: https://github.com/odoo/odoo/commit/cae188514fa8b0a7c785a630ac4aff677b2071fa The intent was to disable buttons in form views until html fields are fully loaded, but it was not disabling the buttons for the following reasons: 1. It is looking for buttons in the DOM, although they are not already attached into the body at this moment. 2. It was disabling the buttons only at widget start(), so only once after "Empty Cache and Hard Reload". We propose a better solution than disabling the buttons in the control panel: when we click on "Save", the html field ensures that it is fully loaded while commiting the changes.
