Hi, Im having probelms getting processing to recognise the different set of data during serialEvent()

I have data coming in every 4 seconds for live graphing, when a button is pressed on my interface it sends a string to my arduino requesting different types of data,once the data is through the arduino continues sending the 4second data, I have tested it on the arduino serial monitor and its working as expected but processing is not grabbing the data and parsing it. Im having little success with this serialEvent() I have set both data packets with start and end packet markers of [] and {}.

1. void serialEvent(Serial myPort){
     println("Called");
     int mapped_tempc = 0;
     int mapped_rh = 0;
     int mapped_ldr =0;
     if(myport.read() == '[')
     {
       print("Data");
       String inString = myport.readStringUntil(']');
       inString = inString.substring(0, inString.length() - 1);
       if(inString != null )
        {
        inString = trim(inString);
        int inputs[] = int(split(inString, ','));
