Related to this, I'm finding that it's not working even when I attempt to output the errors correctly. In my controller I have this (just to test):
public function testAction($id)
{
$rules = ['foobar' => 'required'];
$validator = Validator::make(Input::all(), $rules);
return Redirect::back()->withErrors($validator);
}
And in the view I have:
<pre>
<?php var_dump($errors) ?>
@foreach ($errors->all() as $error)
{{ $error }}
@endforeach
</pre>
When I view this in an actual browser it shows this:

But the output for that section when checking with Integrated's ->dump() method is this:
<pre>
object(Illuminate\Support\ViewErrorBag)#278 (1) {
["bags":protected]=>
array(0) {
}
}
</pre>
So it looks like in my case using a redirect withErrors() also isn't working.
Do you have any suggestions of where I should start looking to debug this?
Thanks, Harrison
