Hi, Place a small validation on the indicated method that showed a message with the Dialog component when the condition is met. To my surprise the message appears 2 times in a row. Validate that you were not changing the content of the field (textarea component) in any other point of the logic.
My code: txTamano.addActionListener((e) -> { if (!txTamano.getText().isEmpty()) { if (!*unidadMedidaValida*(txTamano.getText(), unidadMedida())) { Dialog.show(idioma.getAdvertencia(), idioma.getMensaje57(), idioma.getContinuar(), null); } } }); public boolean *unidadMedidaValida*(String uMa, String uM[]) { boolean resp = false; String umArticulo = new String(); for (int i = 0; i < uMa.length(); i++) { char c = uMa.charAt(i); if (c >= '0' && c <= '9' || c == '.' || c == ' ') { continue; } umArticulo = uMa.substring(i, uMa.length()); break; } if (!umArticulo.isEmpty()) { for (int x = 0; x < uM.length; x++) { String[] pA = Util.split((String) uM[x], " "); for (int y = 0; y < pA.length; y++) { if (umArticulo.toLowerCase().equals(pA[y].toLowerCase())) { resp = true; break; } } } } return resp; } -- You received this message because you are subscribed to the Google Groups "CodenameOne Discussions" group.
