"array" type: Not working for arrays of DateTime objects

[lukey78]

I recently tried to use the following annotation that should work as documented:

@JMS\Type("array<DateTime<'Y-m-d'>>")

But it doesn't. The DateTimes are serialized to empty strings.

While investigating the problem I found that line in the visitArray function of (e.g.) the GenericSerializationVisitor:

   $v = $this->navigator->accept($v, isset($type['params'][1]) ? $type['params'][1] : null, $context);

$type['params'][1] normally doesn't exist. The accept function is called with a null type which results in auto detection of the type.

If I change the $type['params'][1] to $type['params'][0] everything seems to work as expected.

Is this a bug or a feature? I could also submit a pull request if this is a bug.

Thanks,
Jens
