[macosx] Clicking with trackpad on Mac OS X on swing components generates java.awt.IllegalComponentStateException

    XMLWordPrintable

    Details

    • Subcomponent:
    • CPU:
      x86
    • OS:
      os_x

      Description

      FULL PRODUCT VERSION :
      1.8.0_45

      ADDITIONAL OS VERSION INFORMATION :
      OS X Yosemite version 10.10.4

      EXTRA RELEVANT SYSTEM CONFIGURATION :
      trackpad with setting "tap for a clic"

      A DESCRIPTION OF THE PROBLEM :
      If you use some Swing component (perhaps in JavaFX too), perhaps like a JComboBox and you clic for a selection, you become a "java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location".

      After some hours of test, i see that comes only if you are setting "a tap make a clic" on global trackpad setting and you make tap on your java application. If you clic (not a tap) it's ok (with a true mouse, it's ok too). For me is clearly a bug in Java 8 (perhaps with 7 too).

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Use a JComboBox with some elements in model in a small Java Swing application
      2. Tap for a clic when you select an entry
      3. See the error message

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      No IllegalComponentStateException with a tap for a clic in Mac OS.
      ACTUAL -
      IllegalComponentStateException
