Components of the forms disappear II

[rdvg...@gmail.com]

Hi,

On August 27, I wrote version one of my question: " Components of the forms disappear". Today I checked the code and found nothing, I proceeded to change it to minimize its size but I still have the same problems. The truth is that it happens in at least 3 forms of my application and added to this I find that a form with the dialog component grows or changes its form without changes in programming. I must clarify that my application handles many records and I smell that it is due to a problem with memory.

I show you the ways mentioned and the code changed.

   private void formaTienda(final Form fmLiber) {

        final Form fmTienda = new Form(new BorderLayout());

        fmTienda.getToolbar().setBackCommand("", e -> fmLiber.showBack());

        fmTienda.getToolbar().getStyle().setAlignment(Label.LEFT);

        fmTienda.setTitle(idioma.getTiendas());

        TextField txNombreTienda = new TextField();

        txNombreTienda.setHint(idioma.getTienda());

        Container cnTiendas = new Container(BoxLayout.y());

        cnTiendas.setScrollableY(true);

        txNombreTienda.addDataChangeListener((int type, int index) -> {

            String t = txNombreTienda.getText();

            if (t.length() == 0) {

                return;

            }

            char[] p = t.toCharArray();

            if (p.length == 0) {

                return;

            } else {

                if (p[p.length - 1] != ' ') {

                    return;

                }

            }

            ArrayList l = new ArrayList();

            l = dT.leeArrayListDatos(t, TIENDA_LEE_NOMBRE);

            if (l == null || l.isEmpty()) {

                return;

            }

            if (l.size() < LIMITE_DATOS) {

                cnTiendas.removeAll();

                for (int i = 0; i < l.size(); i++) {

                    Tienda tDa = registroTienda((Map<String, String>) l.get(i));

                    Container cnItemTienda = creaItemTienda(fmTienda, tDa);

                    cnTiendas.add(cnItemTienda);

                }

            } else {

                Dialog.show(idioma.getInformacion(), idioma.getMensaje21(), idioma.getContinuar(), null);

            }

            cnTiendas.animateLayout(250);

        });

        Style s = UIManager.getInstance().getComponentStyle("Title");

        FontImage iInformacion = FontImage.createMaterial(FontImage.MATERIAL_INFO, s);

        fmTienda.getToolbar().addCommandToRightBar(new Command("", iInformacion) {

            @Override

            public void actionPerformed(ActionEvent evt) {

                formaInformacion(fmTienda, idioma.getTiendas(), idioma.getMensaje68() + idioma.getMensaje32());

            }

        });

        FloatingActionButton btNuevo = FloatingActionButton.createFAB(FontImage.MATERIAL_ADD);

        btNuevo.bindFabToContainer(fmTienda.getContentPane(), Component.RIGHT, Component.BOTTOM);

        btNuevo.addActionListener((e) -> {

            Tienda tDa = new Tienda();

            mantenimientoTienda(fmTienda, tDa, ADICIONAR);

        });

        fmTienda.add(BorderLayout.NORTH, txNombreTienda);

        fmTienda.add(BorderLayout.CENTER, cnTiendas);

        fmTienda.setTransitionOutAnimator(CommonTransitions.createSlide(

                CommonTransitions.SLIDE_VERTICAL, true, 500));

        fmTienda.show();

    }

Hi,

you would see a crash if a memory issue was involved. I suggest looking at the console for the device and seeing if something was printed when this happened.

Use a process of elimination to try and determine the part of the code that's responsible for this issue.

Hi,

I am a man older than 50 and I skipped java and object oriented programming to work on codename one.

I have doubts about the console you mention. Is the debug console that has my IDE (netbeans) or  what?

Hi,

the console of where this is happening. The console for the device if it happens there. For Android you can debug with a cable and for other devices there is this cn1lib https://www.codenameone.com/blog/native-logging-certificate-wizard.html
