[codenameone-discussions] addActionListener method runs 2 times.

[rdvg1962]

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;
    }
