In a DXA 1.7 .NET web application I have several custom DXA modules. After I moved a few models, views and controllers from one module to the other I got this routes error for one of the entities.

This shows up in the browser

A problem occurred while rendering this section
No route in the route table matches the supplied values.

The log recorded this error

What could cause this error?

  • Are you able to compile the webapplication after moving the items?

  • Yes, I can compile the web application, if it would not compile I could not run it to get this error ;)

  • Have you updated the metadata fields of the Component Templates that use those views/controllers so they point to the correct module, and are they republished correctly?

Reset to default

In the RegisterArea() method of my module registration class (the one which extends BaseAreaRegistration), I did not call base.RegisterArea().

At the same time for an experiment the RegisterAllViewModels() of the module was called in a different way. Hence the registration of views and viewmodels worked fine, but the module's controllers did not work.

It appears that BaseAreaRegistration.RegisterArea() does register a default entity route. I do not know what exactly it does, but without it your custom controllers don't work.

For a .NET MVC Web application, Routes are registered in applictation_start method. Can you check whether you have these lines available in your web application's global.asax.cs file -> application_start method, 

    RegisterRoutes(RouteTable.Routes);
    AreaRegistration.RegisterAllAreas();

verify that you have not modified the RegisterRoutes(RouteCollection routes) in the DXA web application which might also causes issues
