You just can’t seem to get the URL that you expect and all the forums say just call createUrl and it’ll do everything for you!

Na-ugh! Wrong!  It’s returning just the action – or the controller/action but not the module.

First

First check your UrlManager rules because these are central to how createUrl builds the URL. If you’ve left out a “/” or your URLs are ending in “/”s then createUrl will get confused.

Then …

Check that you are calling Yii::app()->controller->createUrl (which can often be $this->createUrl() ) rather than Yii::app()->createUrl() as the latter will not return relative URLs!

That’s it – you should be working now
