Namespace could not be resolved. This exception should never be thrown!¶

Most likely, you're using a ViewHelper or something that has its own namespace, but you didn't declare that namespace (e.g: missing {namespace myNamespace=Tx_MyExt_ViewHelpers} or with PHP namespaces: {namespace myNamespace=Vendor\MyExt\ViewHelpers}).
The quite common instance is using a VHS View Helper (e.g.``v:extension.path.resources``) without referencing the VHS namespace ({namespace v=Tx_Vhs_ViewHelpers}).
Also keep in mind that you may be required to declare namespace(s) in the partial(s) even though they where declared in the parent template.
