Mam problem z Caretem, Caret nie mrugnął bez focusGained (patrz kod w Swing Action) na 2. JTextField i powrót do 1. JTextField

jak poprawnie zastąpić DefaultCaret # setBlinkRate ()

(bez nadpisywania Caret) domyślnie Caret na końcu dokumentu i miga na 1. focusGained

testowany na win7_32b, Java7.011 / 025 / Java6

przetestowany z kilkoma standardowymi L&F, również niestandardowy, każdy spowodowany tym samym problemem
