Redirect latte problem, “No route for Dashboard:”

Hi,

in my presenter, there is simple function:

	public function pickChildFormSucceeded($button)
	{
		$values = $button->getForm()->getValues();
		$name =  $values['child'];
		$this->flashMessage($name);
		$this->redirect('child_overview');

	}

I prepared latte file child_overview.latte in app/presenters/templates/Dashboard

{block content}

<h1>Hello world</h1>

but when I click button and initiate that function I get error: No route for Dashboard:child_overview()
when I put $this->redirect(‘default’); it works fine. So did I forget to add child_overview.latte to some configuration file?

Thx
