populate combobox code:

ComboBox getCategoryComboBox = new ComboBox();

getCategoryComboBox.addItem("Choose Category");

for (Map<String, Object> entry : alacc.responseCategory) {
    String categoryName = (String) entry.get("name");
    String categoryId = (String) entry.get("id");//how to set this to combobox item

categoryId is taken from for loop above, how to set it in each combobox items? I need to get the categoryId of each selected combobox item, how can i get this?

You have several ways to do this.

One way is to just do:


Which would provide you the full entry on getSelectedItem() effectively solving that problem.

To make the name render properly though you would need to do this:

cb.setRenderer(new DefaultListCellRenderer<Object>() {
   public Component getCellRendererComponent(Component list, Object model, Object value, int index, boolean isSelected) {
      if(value instanceof Map) {
         value = ((Map)value).get("name");
      return super.getCellRendererComponent(list, model, value, index, isSelected);

Notice you will also need to define the theme constant otherPopupRendererBool to false for this to work properly.
