ControlP5 error with Processing 2.06 alpha

[GoogleCodeExporter]

What steps will reproduce the problem?
1. trying to run a ControlP5 example (as an example I used ControlP5button).

What is the expected output? What do you see instead?

Exception in thread "Animation Thread" java.lang.NoSuchFieldError: online
    at controlP5.ControlWindow.<init>(Unknown Source)
    at controlP5.ControlP5.init(Unknown Source)
    at controlP5.ControlP5.<init>(Unknown Source)
    at ControlP5button.setup(ControlP5button.java:48)
    at processing.core.PApplet.handleDraw(PApplet.java:1952)
    at processing.core.PGraphicsJava2D.requestDraw(PGraphicsJava2D.java:187)
    at processing.core.PApplet.run(PApplet.java:1855)
    at java.lang.Thread.run(Thread.java:680)

What version of the product are you using? On what operating system?

ControlP5 0.75 on Processing 2.06 alpha on MacOsX Lion and Snow Leopard with 
Java 6.0_31

From the Processing changelog:

"The 'online' boolean has been renamed to 'appletViewer'. The reason is that it 
had nothing to do with whether a sketch was online (i.e. had a net connection), 
but rather it would return true if the sketch was running inside a web browser 
or applet viewer. (Technical version: whether a Java AppletContext existed.) 
This caused some complaints/confusion."

Hope this helps.

I was able to recreate the library in Eclipse, change all (two) instances of 
"_myApplet.online" to "_myApplet.appletViewer", and recompile, and then open 
several examples successfully. It looks like these simple changes (in 
ControlP5.java and ControlWindow.java) did the trick.

Here's a zip file of the edited and recompiled library for anyone wanting to 
use controlP5 0.7.5 with Processing 2.0a6 in the meantime before a new release. 
(YMMV, this has not been thoroughly tested.)

Thanks alot for the comments and your recompiling! Cannot find the zip file 
here. Can you upload it again or email it?

Thanks!

Oh yeah, I guess the attachment didn't work. Here's a DropBox link instead:

I guess this renamed variable will mean controlP5 will have to have separate 
Processing 1 and 2 versions (since in Java you can't test for the existence of 
a variable; mentioning a non-existent variable at all causes an error at 
compile time).

the reference to processing's online variable has been removed with 0.7.6
