InputFilter not populating/using FallbackValue for Input

[weierophinney]

After updating from Version 2.3.5 to the newest Version i'm running into following error.

I'm creating an new InputFilter creating the Inputs in __construct() like this:

class ListDataInputFilter extends InputFilter {
    public function __construct() {
        $page = new \Zend\InputFilter\Input('page');
        $page->setFallbackValue(1);
        $this->add($page);
    }
}

Then i'm calling

// empty to demonstrate behaviour
$filterParams = array();
$filter = new ListDataFilter();
$filter->setData($filterParams);
if(!$filter->isValid()) {
    var_dump($filter->getMessages());
}

With Version 2.3.5 it's worked as expected. Populating the Fallback Value and not throwing an Error. But with 2.5.* instead of filling the Page Input with the Fallback Value it's empty and the Filter is not valid.

@disasterdrop I've verified the issue, and:

• created unit tests to cover the fallback value behavior, as we did not have any in the input filter tests (only the input tests);
• created a patch to address the issue.

Please check the tests to make sure they're testing the behavior you need, and we'll get a release out with the fixes.

When approved, we'll also release a 2.4 LTS version with the fix.

I've reviewed and it looks good to me. Feel free to merge.

@disasterdrop Why did you close this? We haven't merged the patch yet!

Sorry for that...
I'm relative new to git and thought i would approve that your code was the right behaviour, after i testet your fix, liked you asked me to do.

Should the input to be append to validInputs collection?
