MetacatUI

I was able to recreate this error in themes in which the router renders a view when there is no hash string in the URL. When the app directly renders these views, it does not navigate to the view in the browser, which is two separate things. These themes will now actually navigate to the view itself by changing the window location in the browser. A default view can be set up in the appModel to define which view to navigate to in these cases. I set the default view in all themes to "data", except for the NCEAS theme which has no DataCatalog view, so it's default is the registry.

I also added error handling to the router to avoid things like this from happening in the future. Now, when the router cannot find a match for the given hash string, it will redirect to the aforementioned default view.

Changes have been made in the 1.6 branch and master.

The router uses this Backbone.js plugin to find when a router has not found a match (i.e. 404): https://github.com/STRML/backbone.routeNotFound
