Issue

  • When a service expects lists of objects, and I want to pass them as a JSON string in Liferay's JSON-WS UI, it returns with NoSuchMethodException. An example string is:
    [{
    "+simplefoo": "poc.db.model.impl.SimpleFooImpl",
    "uuid": "23a91bec-bdae-783f-0825-b3176546a0e9",
    "simpleFooId": 1234,
    "field1": "randomstring",
    "field2": "false",
    "field3": 155231223630625
    }, {
    "+simplefoo": "poc.db.model.impl.SimpleFooImpl",
    "uuid": "asdf1bec-bdae-783f-0825-b3176546a0e9",
    "simpleFooId": 123,
    "field1": "otherrandomstring",
    "field2": "false",
    "field3": 155231223630625
    }]
