Objects in a "array" dont seem to get validated

[grub2]

With 0.4.1, type validation seems to not happen for objects that are within an 'array' type.
Example:

JSON Schema:

{
"properties": {
"age":{
"type":"integer"
"required":true
}

}
}

validates the JSON instance for numeric types
wheras if the same 'age "object was enclosed in an "array" no numeric type validation occurs.
It allows "abc" against "age"
