ControlP5 Logic problem

I have a java file and a processing file.
FoodData.txt looks like this:
ham
23
30
50
50
100
corn
5
10
5
10
15.5
In the function checkForFile(),
println (food[x].toString()) gives the right information as:
ham
23
30
50
50
100
corn
5
10
5
10
15.5
However, when I use the function LIST() to the textarea called searchList.
The information of ham changes into that of the corn like this:
ham
5
10
5
10
15.5
corn
5
10
5
10
15.5...
you need to compare the two in the interactive console, not on the actual window.
import controlP5.*;
ControlP5 controlP5;

//OUTPUT
Textarea searchList;

//FOOD
final int maxFood = 100;
private Food []food = new Food[maxFood];
private int numFood = 0;
void setup()
{
size(1000,500);
background(255);
frameRate(30);
controlP5 = new ControlP5(this);
//Search
search = controlP5.addTextfield("",50,50,150,20);
controlP5.addButton("SEARCH",0,210,50,50,20);
searchList = controlP5.addTextarea("lable1","List",50,90,150,300);
searchList.setColorBackground(0xff0066cc);

for (int x = 0; x<numFood;x++)
{

println (food[x].toString());
}

}

}
food[x] = new Food(name,nutrient);
println(food[x].toString());
x++;
}
numFood = x;
LIST(); //List function
inFile.close();
return true;
}
catch (IOException io) {
println(io.getMessage());
}
return false;

When you type "ham" and press "search" and press "ham" and "search" then I get this error:
Apr 13, 2012 10:45:52 AM controlP5.ControlBroadcaster printMethodError
SEVERE: An error occured while forwarding a Controller value
to a method in your program. Please check your code for any
possible errors that might occur in this method .
e.g. check for casting errors, possible nullpointers, array overflows ... .
method: search
exception: java.lang.reflect.InvocationTargetException
Also if I search"ham" and search"corn", it gives that error too.
Please Help!

50
I am having an error if I put "ham" in the textfield and press "Search" many times.
Also, I am having an error when I put "ham" and press "Search" and later put "corn" and press "Search".
I am having an error on addItems methods, but I don't know why....
My console says:
