BC break between 1.1.0 and 1.1.1 with custom property_path

[Gregoire-M]

Hi,

When using a custom property_path (I mean different than "finiteState"), there's a BC break when updating from v1.1.0 to v1.1.1, caused by the commit c7a5672

Before the update, I construct my state machine this way:

        $config = /* I get my config array... */
        $loader = new ArrayLoader($config);
        $stateMachine = new StateMachine($object, $this->eventDispatcher);
        $loader->load($stateMachine);
        $stateMachine->initialize();

$config['property_path'] is set to a custom path. ArrayLoader::load constructs a PropertyPathStateAccessor with this property. Everything works fine.

After the update to v1.1.1, when I construct my state machine the same way, a default PropertyPathStateAccessor is constructed in ArrayLoader's constructor. So ArrayLoader::load sees that a state accessor is set, so it does not constructs a new one with the configured property path.

So the state machine doesn't have the right property path.

To fix this, I have to change the way I construct my state machine, as follows:

        $config = /* I get my config array... */
        $loader = new ArrayLoader($config);
        $stateMachine = new StateMachine(
            $object,
            $this->eventDispatcher,
            isset($config['property_path']) ? new PropertyPathStateAccessor($config['property_path']) : null
        );
        $loader->load($stateMachine);
        $stateMachine->initialize();

Ho, it was actually already reported in #117 / #118

Since this is not only a BC break, but renders the ArrayLoaders functionality unusable for the property_path, this library should be considered broken and abandon-ware.

Please mark it as such @yohang . There is no shame in it.
