I feel this should be really simple, but I can't make it work.
I want to create a link to the current page, whatever that might be, and simple change the "lang" parameter. Basically to have a link in the corner that changes language but leaves you on the same page.

My best attempt yet is this:

```
//current url: 'da/articles/view/1'
$this->Url->build(['lang' => 'en']);
//returns '/en/articles/view'

```

So, how do I get it to retain the passed param 1, which of course is the id of the article? Mind you, I have other controllers for which I would like this to work so simply doing this won't do, although it works:

```
$this->Url->build(['controller' => 'Articles', 'action' => 'view', 1, 'lang' => 'en']);

```
