Numeric string detection

[RTC1]

No option is selected if the value has been cast as a string, such as when from a form input, due to the new type comparison.

This keeps the type comparison in place, but casts strings as integers where appropriate.

Thanks, Rob.

Hmm I think this probably broke stuff.

$value = "5";
dump(is_string($value)); // true
dump(is_numeric($value)); // true

See http://php.net/manual/en/function.is-numeric.php

And Laravel doesn't really cast proper values, so you are forcing one thing to int, the other you leave as string. Probably need to cast both strings as int, or us is_int

Sorry this seems to fix it. It was probably #447 that gave problems, but this commit isn't tagged yet.

Might be worth trying this fix to see if it resolves your issue with #447.

[barryvdh]

Yes it did.

Could this fix be tagged? Without the latest commit, all my dropdowns don't keep their value when editing :(
