Processing 2.06 OpenGL error I don't understand

in Core Library Questions • 1 year ago

Hey Folks,

much thanks and appreciation for updating to 2.06!

I downloaded the new Processing 2.06alpha for MacOSX and tried to run my programm which uses the OPENGL   P3D renderer, that works fine with 2.05.
(I tried running it on Lion and Snow Leopard)

I get the following error message:

Exception in thread "Animation Thread" javax.media.opengl.GLException: java.lang.NoSuchFieldError: online
    at jogamp.opengl.awt.AWTThreadingPlugin.invokeOnOpenGLThread(AWTThreadingPlugin.java:98)

    at java.lang.Thread.run(Thread.java:680)

I have no idea, since I don't even have anything called "online".... any ideas what could cause this?

Thanks in advance!

Hi, unfortunately the error messages in OpenGL got messier in the 2.0a6 release, we will try to address this somehow.

In your case, the error seems to come from the use of the online variable, which actually got renamed as appletViewer in the new release, the changes entry in the wiki still doesn't mention this update though. Are you sure you are not referring to the online variable anywhere in your sketch? If not, and your sketch is not too long, could you post it here? Thanks.

Dear Andres,

I figured out that the problem is with the Contributed Library ControlP5 I am using.I will post the problem to the controlp5 issues board.
I updated to the newest version of that but there seems to be a problem since also the ControlP5 examples give the same mistake.

Exception in thread "Animation Thread" java.lang.NoSuchFieldError: online

// create a new button with name 'buttonA'
cp5.addButton("colorA")

ok, so this problem is that controlP5 is using online within its code. We will need to wait for an update from Andreas then.

Re: Processing 2.06 OpenGL error I don't understand

Hello Andres, to make controlp5 work with processing 2.0.a6 and newer I would have to make changes in case of the 'online' field. This comes with a surprise and I doubt I will be the only one having to make adjustments.

I can understand that people complain or get confused about the naming of certain fields, but this change has a larger effect on 3rd party contributions and sketches created with older version that make used of this particular field - since it was defined public, and therefore was not prevented for others to use, backwards compatibility becomes very difficult to handle here.

Code goes through changes and parts get replaced, renamed, etc. but I am wondering if the removal of publically accessible fields or methods could be handled more backwards compatibility friendly, therefore I am proposing to keep the online field (as deprecated) and only set it to true or false where necessary to mirror the appletViewer field inside PApplet. (with r9697 this will affect the try catch block inside PApplet lines 834-839 and the reimplementation of field online)

Hi Andreas, I will pass your comments on to Ben, since he is the one in charge of these API updates.

Andreas,

How are you using the 'online' variable in controlp5? I was actually about to remove it altogether (instead of renaming), since it's more trouble than its worth, but failing that, perhaps we'll just change the name back to 'online', even though it has little to do with being online.

Re: Processing 2.06 OpenGL error I don't understand

Thanks Andres.

Hi Ben. I am using the 'online' variable to determine if a sketch is running in applet mode. In case a function or variable used by controlp5's reflection is not public, a warning message is triggered and printed to the console when in applet mode. I will remove this part and handle it differently. Nevertheless, in case the 'online' variable is removed from PApplet, there is still the possibility of conflicts if someone is using an older version of controlp5 with the latest or future versions of processing and this will throw the same error message as in mrweix 1st post.

Therefore, changing the name back to 'online' would be the most helpful solution here, although the misleading of the name 'online' would remain. What do you think?

Hey Guys,

thank you for discussing this topic. Ben and Andreas, have you decided yet how this is going to be solved? From what I read in your answers it looks like probably the Processing core will change back to use the "online". Is this going to get integrated in the 2.06 release or in a new 2.07? Or did you find a possible work-around how to make controlp5 work with 2.06?

Thanks alot!

I get the following error message:

I think the online variable will stay, but marked as deprecated. As for the "quality" error message reported by Carlo, I haven't seen it myself. Does it happen with 2.0a6?

ben.fry

Re: Processing 2.06 OpenGL error I don't understand

Yes, 'online' is back (but deprecated) for 2.0a7 when that arrives.

The 'quality' error sounds like someone put the processing.opengl.* classes into a library that you're using and an old version is conflicting with the versions sound with Processing.

Hey Guys;

"

I'm just wondering about the status of controlP5 in 2.0a6. Have yall figured out a way to get it running stably in 2.0a6? Or is it something that will be happening with 2.0.a7?

Thanks so much for this library and making it so dope!

Zack

Hi, you can find a list of controlP5 versions that work with the various/previous releases of processing including 2.0b6 and 2.0b7, have a look here http://code.google.com/p/controlp5/downloads/list
