Master-detail form help

I have a combobox populated from a list of objects. On a selection in the combobox, I'd like to display certain properties of the selected object. Any help on how I should achieve this ?

Domain object looks like this:

public class SearchDescriptor
{
String title;
MapLayer[] layer; // combobox binding used for this
}

public class MapLayer
{
PropertyDescriptors[] properties; // I'd like to display this dynamically on combobox selection
}

Now I can always create a binding that generates the controls for the properties but I'm not sure how to do that dynamically.

I had a similar problem and have done the actualization of the selectable values using a RefreshableValueHolder:

Code:

---

        private class YourValueHolder extends RefreshableValueHolder{
                public YourValueHolder() {
                        super(new Closure() {
                                public Object call(Object arg0) {
                                        return "retieve your data from the selected object";
                                }
                        }, false, false); //alwaysRefresh ainda não funciona - springrcp1.0.0);
                }
        }

        private YourValueHolder yourValueHolder = new YourValueHolder();

---

Then I overrided the method below in the AbstractDetailForm returned by createDetailForm(...):

Code:

---

                        @Override
                        protected void setEditState(int editState) {
                                if(editState != 0) {
                                        yourValueHolder.refresh();
                                }
                                super.setEditState(editState);
                        }

---

Or you can just add a property change listener and call yourValueHolder.refresh();

Your combobox can be binded as:

Code:

---

bindingFactory.createBoundComboBox("formProperty", yourValueHolder);
