Mostra esse método.

@rafaspara2017 foco para o que interessa na mensagem, numa an√°lise de 1¬ļ n√≠vel:

O Caused by diz o que causou aquele erro l√° de cima.

IllegalStateException é a exceção que você precisa tratar.

Esse é o motivo de ter causado a exceção.

E essa exceção foi causada pelo comando que está na linha 403, dentro do método configuraBinder(), o qual está dentro de VendaView.java

√Č assim que voc√™ interpreta, inicialmente, a mensagem de erro.

Vi que você tem o costume de postar mensagens de erro assim.Tenta ser mais objetivo nas suas debugagens. Bons estudos!

@Fefo80…obg pelo ensinamento…valioso para meus estudos!!!

@RoinujNosde

obg por responder, mas estranhamente hoje, sem eu fazer nada, ele parou de dar erro…rs…caso volte, posto novamente…obg!

@RoinujNosde

não é o mesmo erro, mas se puder ajudar, fico grato
