Problem with custom JSON miner extractor

[abaker2]

I am trying to pull a JSON feed that in CURL looks like this:

[
    {
        "dhcphost_id": "105",
        "dhcplease_end_time": "0",
        "dhcplease_id": "0",
        "errno": "0",
        "ip_addr": "52a6203e",
        "ip_alias": "test.test.com,
        "type": "ip"
    },
    {
        "errno": "0",
        "type": "ip",
        "ip_addr": "52a62038",
        "name": "test2.test.com",
    }
]

 Each {} is a different device that i then want to use a few fields from each device (such as ip_addr, name) within minemeld. 

I am having problems creating the extractor/indicator combination though. Currently, I either have it fail to restart, or it comes back saying the list object has no items.

I used one of the existing JSON miners to modify for this miner, so the class is minemeld.ft.json.SimpleJSON 

Any suggestions?

Thanks!
