Hello,

i am doing a List of hours, so inside every cell i set the hourLabel and i need to write 3 arrayList of different activities(each activity is a button that i click and then go to another View).

My Layout in the constructor is a TableLayout(1,2), in the first column there is the hourLabel, and in the second column i got the Container for the activities.

So, in my getListCellRendererComponent function i set the label, i got an ArrayList value associated to the hour, so i add a button to my activity container for every activity in the value.

The problem is: i got 9 activities on hour 10, but my listrenderer draws 9 activities for every Hour! Maybe because i'm doing an addComponent to the same Container?

I managed to solve the problem putting a activityContainer.removeAll() at the start of my cellrenderer, so the output is correct but the buttons loose the action listener, i can't click them.

The code is like this:

public Component getListCellRendererComponent(List list, ArrayList<Attivita> value, int index, boolean isSelected) {
        attivita.removeAll();
        
        hour.setText(String.valueOf(index));
        
        for (int i=0; i < value.size(); i++) {
            final Attivita v = value.get(i);
            if(v != null) {
                if(v instanceof Chiamata) {
                    button = new Button("Ch");
                    button.addActionListener(new ActionListener() {

                        public void actionPerformed(ActionEvent evt) {
                            Dialog.show("Alert", v.getDescrizione(), "Ok", null);
                        }
                    });
                    //button.setUIID("Label");
                    attivita.addComponent(button);
                    
                }

                if(v instanceof Appuntamento) {
                    button = new Button("A");
                    button.addActionListener(new ActionListener() {

                        public void actionPerformed(ActionEvent evt) {
                            Dialog.show("Alert", v.getDescrizione(), "Ok", null);
                        }
                    });
                    //button.setUIID("Label");
                    attivita.addComponent(button);
                    
                }

                if(v instanceof Compito) {
                    button = new Button("Co");
                    button.addActionListener(new ActionListener() {

                        public void actionPerformed(ActionEvent evt) {
                            Dialog.show("Alert", v.getDescrizione(), "Ok", null);
                        }
                    });
                    //button.setUIID("Label");
                    attivita.addComponent(button);
                    
                }
            }
            
        }
        
        return this;
    }
