Disco party error on Mac

I cannot seem to use disco party with my Blinkytape. The java.lang.NullPointerException error comes up whenever I run it.

I am using Mac OS X version 10.6.8 and I am running processing 2.0.3. Any help with this problem would be greatly appreciated.

  • Hey bttoddx - could you paste in the top & bottom lines of the error? We'll try to recreate it. You're using DiscoParty without modifications, correct?

    You are running Processing revision 221, the latest is 224.

    Yes, I am running disco party without modifications.

    The bulk of the errors come up after I click the link to connect to a Blinkytape. The program senses the hardware in the port, but there is an error afterwards.
  • It sounds like there is a permissions problem with the serial port. Recent versions of Processing have a fix for it; see if there is an item in the Tools menu called "Fix Serial Permissions" (or similar).
  • That seems to do the trick, thanks much Matt.
