Gunna,
First of all, thank you very much for your help. But unfortunatelly, as you
said in the last paragraph of your email (if I understood you correctly),
you only show keys in your selected list, while I must show both keys and
labels.
I am still trying to make my model fit the selected list, but I'll get
there. This Palette is a tricky fellow...

Hi Rui,
I try to simulate your problem, here is my working code.
Hope there's no miss perception here..
here is my CustomModel,
import org.apache.tapestry.form.IPropertySelectionModel;
public class CustomModel implements IPropertySelectionModel{
private String[] keys = {"G","S","H","K"};
private String[] values = {"Gunna","Satria","Hijrah","Kusumah"};
public CustomModel(){
}
/* (non-Javadoc)
* @see
org.apache.tapestry.form.IPropertySelectionModel#getOptionCount()
*/
public int getOptionCount() {
return keys.length;
}
/* (non-Javadoc)
* @see org.apache.tapestry.form.IPropertySelectionModel#getOption
(int)
*/
public Object getOption(int arg0) {
return keys[arg0];
}
/* (non-Javadoc)
* @see org.apache.tapestry.form.IPropertySelectionModel#getLabel(int)
*/
public String getLabel(int arg0) {
return values[arg0];
}
/* (non-Javadoc)
* @see org.apache.tapestry.form.IPropertySelectionModel#getValue(int)
*/
public String getValue(int arg0) {
return keys[arg0];
}
/* (non-Javadoc)
* @see
org.apache.tapestry.form.IPropertySelectionModel#translateValue(
java.lang.String)
*/
public Object translateValue(String arg0) {
int index = 0;
for (int i = 0; i < keys.length; i++) {
if(arg0.equals(keys[i])){
index = i;
break;
}
}
return values[index];
}
}
here is my code in page class providing selected list and the model,
public IPropertySelectionModel getModel(){
return new CustomModel();
}
public List getSelected(){
List list = new ArrayList();
list.add("S"); //list content is amongs keys array defined in
CustomModel
list.add("H");
return list;
}
the problem is maybe in the content of your selected id list, it is
really same as in the one you define in the model. In my simple case,
selected list filled with "G","S","H", or "K" not with "Gunna", "Satria"
etc.
cheers,
Gunna

I think I'm having problems because I use a custom model for my
PropertySelection and Palette.
I am using a model that has both values and labels, the values being
defined
not by the position of the label on the drop down but by an ID that I
fetch
from the database.
The content of that model is a type I defined as an interface with getters
and setters for an int and a String,
Now, I tried setting the selected elements of my Palette with both a List
of
the inner class that holds the values for my model and a List of models,
each with only one value. Neither worked.
Can anyone help me with this one?
Many thanks,
Rui
