QWeb's LazyResponse mechanism allows controllers to be inherited and to alter the rendering context (qwebcontext) *after* calling super(). However it caused the final rendering to occur outside the protection of the @service.model.check decorator that handles concurrent access errors. In rare cases the lazy rendering can be interrupted by a concurrent access error, for example when bootstrapping the the cache of asset bundles (as it INSERTs a bunch of attachments). By forcing the flatten()ing of the lazy response earlier, right after calling the route's endpoint(), it occurs within the protection of the @service.model.check, and benefits from the automatic retry. flatten() was modified to avoid rendering twice the template The flatten() in get_response() is still necessary for addons code that directly calls get_response(). Moved QWebException into openerp.exceptions next to the other exceptions classes - since it now has more global semantics. ~ The whole request dispatching code could really do with a complete redesign/simplification.
