Hi,
here is a (for me) working code snipplet populated from the example given by
Igor:
<snip>
/** SelectedFields may be pojo or so */
/* data */
Selected Fields[] collector;
/* list */
List<SelectedFields> dataList = Arrays.asList(collector);
/* model to save selection */
final Model<ArrayList<String>> fieldsModel;
/* ichoice renderer */
IChoiceRenderer<SelectedFields> renderer = new
ChoiceRenderer<SelectedFields>("selectedValue", "selectedValue");
/* palette */
Palette palette = new
Palette("palette",saveSelectedFields,Model.of(dataList),renderer,dataList.size(),true)
{
/**
*
*/
private static final long serialVersionUID=1L;
@Override
protected Recorder newRecorderComponent()
{
Recorder c=super.newRecorderComponent();
c.add(new AjaxFormComponentUpdatingBehavior("onchange")
{
/**
*
*/
private static final long serialVersionUID=1L;
/* populate every change in selection to palette model */
@Override
protected void onUpdate(AjaxRequestTarget target)
{
/* init cache */
ArrayList<String> tempList=new ArrayList<String>();
/* foreach selected field.. */
for(int a=0; a<saveSelectedFields.getObject().size(); a++)
{
/* get and save the value*/
tempList.add(saveSelectedFields.getObject().get(a).getSelectedValue());
}
/* if at least one is selected */
if(tempList.size()>0)
{
/* save it to model */
fieldsModel.setObject(tempList);
}
}
});
return c;
}
/* publish */
add(palette);
</snip>
Hope this helps.
Best regards
Christoph
