Cocoa Java Tips

• NSTextFormatter is broken out-of-the-box, and has been since the beginning of time (or at least 2000, circa WebObjects 4.5, which also had a ObjC-Java bridge). Fortunately, Benjamin Riefenstahl posted a runtime patch that fixes the problem. Do I even bother filing a bug about this? I know, I know...
• The bridge is not amused when you get your types wrong. Consider this target action code:

  public void updateInitialEstimate(NSFormCell sender) {
    sender.doubleValue();
  }

  This code will unceremoniously terminate your entire process, sans error or exception. You need to do this, instead:

  public void updateInitialEstimate(NSControl sender) {
    sender.doubleValue();
  }

• (Not Cocoa-Java Specific:) In Interface Builder, copying and pasting views (even within the same window) kills all its connections, leading to runtime NullPointerException land when your outlets never get hooked up for you.
• (Also Not Cocoa-Java Specific:) PBX crashes. A lot. Save often.
