What steps will reproduce the problem? 1. Try to interact with a textfield in Processing 2.0b1

What is the expected output? What do you see instead? Expected to be able to write (or move the cursor if there's text) inside a textfield. IllegalArgumentException instead:

java.lang.NullPointerException at processing.mode.java.runner.Runner.findException(Runner.java:664) at processing.mode.java.runner.Runner.reportException(Runner.java:609) at processing.mode.java.runner.Runner.exception(Runner.java:552) at processing.mode.java.runner.EventThread.exceptionEvent(EventThread.java:367) at processing.mode.java.runner.EventThread.handleEvent(EventThread.java:255) at processing.mode.java.runner.EventThread.run(EventThread.java:89) Exception in thread "Animation Thread" java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at processing.core.PApplet$RegisteredMethods.handle(PApplet.java:1076) at processing.core.PApplet.handleKeyEvent(PApplet.java:2848) at processing.core.PApplet.dequeueKeyEvents(PApplet.java:2793) at processing.core.PApplet.handleDraw(PApplet.java:2132) at processing.core.PGraphicsJava2D.requestDraw(PGraphicsJava2D.java:197) at processing.core.PApplet.run(PApplet.java:1998) at java.lang.Thread.run(Unknown Source)

What version of the product are you using? On what operating system? Processing 2.0b1 and ControlP5 0.7.6 on GNU/Linux Ubuntu 10.04 LTS with Java(TM) SE Runtime Environment (build 1.7.0_07-b10)

Please provide any additional information below. You can use the following code to reproduce the error:

import controlP5.*;

ControlP5 cp5;

void setup() { size(256, 256); smooth();

cp5 = new ControlP5(this); cp5.addTextfield("BUG") .setPosition(8, 8) .setSize(128, 20); }

void draw() { background(0); }

Just try to write something inside the textfield. Works fine in the same computer with Processing 1.5.1

It also fails with the new version of ControlP5:

the latest version as of now is 1.5.1 which is only working with processing 1.5.1 and earlier as pointed out here http://code.google.com/p/controlp5/downloads/detail?name=controlP5-1.5.1.zip .

Since there have been many new features, updates, changes and surprises with processing 2.0, controlP5 as is unfortunately breaks and needs to be adjusted. An updated version for post processing 1.5.1 will be available shortly, controlp5's version number will indicated this by changing to 2.0
