Serialization Problem :Table Storage value is Record

Question

Incoming json payload to ASA job in this form:

{"DeviceName":"SP1011",
"SerialNumber":"SP1011",
"PowerMeasurements":{"RmsCurrent":[
    {"Timestamp":"2015-03-24T20:48:14.6670942Z","Line":"A","RmsCurrent":245.9915},
    {"Timestamp":"2015-03-24T20:48:14.6670942Z","Line":"B","RmsCurrent":249.8325}]}
}

The job uses some reference data to match the DeviceName to a Line.  The query is as follows:

SELECT l1.DeviceName, System.TimeStamp as Received, s2l.LineId,  l1.PowerMeasurements
FROM Line1 l1
JOIN LineToDevice s2l ON s2l.DeviceName = l1.DeviceName

Everything works fine except the PowerMeasurements is written to Table Storage with a string value of "Record" instead of the actual array.  Clearly, this is a odd situation but was hoping that the PowerMeasurements value would have held the JSON for so I could deserialize on my own.  Changing the value to "Record" is not that useful.

Is there a work-around today?  Is this something that will be fixed when ASA goes GA?

Thanks,

Jeff
