Fiz uma aplicação de teste para verificar um possivel Bug do Swing…
O evento FocusLost é chamado muitas vezes caso voce adicione um JOptionPane em alguma validação dentro do listner…
O Codigo esta abaixo… estarei eu fazendo algo de errado ?
DETALHE IMPORTANTE… no linux funciona … soh chama uma vez… no Windows… chama umas 4 vezes se vc apetar no “NO” do JOptionPane
Any help ?
