Fix when using empty settings

[jorisvaesen]

Fix for #371

[josegonzalez]

Why not properly setup the settings in the initialize?

[jorisvaesen]

Was thinking the same, just like Hash::normalize too much :)

[josegonzalez]

So after the Hash::normalize() call, detect an invalid config and fix it :)

[jorisvaesen]

Nah, we'd better loop the config ourselfs, otherwise it's doing the job twice. RIP Hash::normalize.

The error is till happening for me. I'm using 3.6.2 version.

Error :
InvalidArgumentException: Invalid data type, must be an array or \ArrayAccess instance.

This works :

$this->addBehavior('Josegonzalez/Upload.Upload', [
	   'thumbnail' => [], 
	]);

This doesn't work :

$this->addBehavior('Josegonzalez/Upload.Upload', [
	   'thumbnail'
	]);

Stacktrace :

Should I open a new issue ?

[josegonzalez]

@KevinMasson mind filing an issue?
