disabling view with in action in ZF2

Question

I am struggling with disabling view in ZF2 $this->_helper->viewRenderer->setNoRender(); or (true) with no luck as it always says there

Answer 1

I would say just disabled the layout only

$viewModel = new ViewModel();
$viewModel->setTerminal(true);

return $viewModel;

and echo your json into your view files...
