ember.js: this.transitionTo('error') does nothing and reports nothing

I want to transition to the error route myself. Within routes/application.js I try

actions: {
  customErrorAction: function() {
    this.transitionTo('error');
  }
}

No transition happens, no errors appear in console etc. Almost like it treats it as a no op?

Okay, the thing to note here is that error routes actually have dynamic segments.

This means that in order to achieve your goal of reusing the error page you must:

Use intermediateTransitionTo so that you don’t get a new URL.
Pass the second models argument: this.intermediateTransitionTo('application_error', true);
Correctly address the error route name, they’re always ${name}_error.

Should be closed as not a bug. @pixelhandler possibly worth improving documentation for this, but seems more power-user-ish.

@adam-knights well, the api docs do say the model argument to transitionTo is optional, http://emberjs.com/api/classes/Ember.Route.html#method_transitionTo

But, in practice… I’ve found that I either use my own routes as error handing, e.g. ‘not-found’, ‘server-error’ etc. or use the error sub-state default behavior (no call to transition to any ‘error’ sub-state in my code).

There seems to be some ‘special’ handing of the error substates that is not obvious via guides or api docs. Personally I don’t think it is a good practice to mix catching an error and transition to the default error sub-states. This is a portion of the ember codebase that could use some more documentation (guides) and/or improvements to the implementation e.g. using transitionTo('error') in your own code.
