Problem receiving intents with Zebra Data Wedge decode_data

Question

I am trying to receive more than one data from the RFID tag (EPC, USER and TID), but from the "intent" I receive empty data. When i use: "com.symbol.datawedge.decode_data"

ArrayList<byte[]> rawData =  
     (ArrayList <byte[]>) initiatingIntent.getSerializableExtra("com.symbol.datawedge.decode_data"); 
if (rawData != null) 
{ 
    byte[] rawBytes = rawData.get(0); 
    for (int i = 0; i < rawBytes.length; i++) 
        Log.d(LOG_TAG, i + ": " + rawBytes[i]); 
}

any ideas? thank you!!
