Its worth mentioning that you can get the String representation of Click
controls by invoking their #toString method. So in the example below you could
build the Decorator return value using a Select control:
public String render(Object object, Context context) {
Select select = ...
...
return select.toString();
}

Hi
I've got a class that extends FormTable. On the Formtable I add a
FieldColumn with a Select component as the field.
I implement a Decorator on this FieldColumn since I need to determine and
manipulate the selected value based on a request attribute.
The problem is that the selected value is never bound to the form.
When I call getRowList I retrieve values for the other columns (using
FieldColumn and Column but no decorator)
It seems like when I implement a Decorator on a FieldColumn the bounding of
the value gets lost.
I've made sure of the following:
1) The FormTable is constructed in the page's onInit
2) The Select is bindable with an annotation - not sure if this is actually
necessary since the FieldColumn itself is bounded.
Here is the code for the FormTable [This all happens in the constructor]
@Bindable
Select selection = new Select("selection");
selection.addAll(someCollection,"label","label");
FieldColumn selectionColumn = new
FieldColumn("admissibilityValue","Admissability", selection);
selectionColumn .setDecorator(new Decorator() {
int i = -1;
public String render(Object object, Context context) {
MyValueObject vo= (MyValueObject )object;
i++;
StringBuffer htmlBuffer = new StringBuffer("");
htmlBuffer.append("<select name='admissibilityValue_" + i + "'
id='table_form_admissibilityValue_" + i + "' size='1' width='100%'>");
Iterator<TimeTypeAdmissibility> ttaList = c.iterator();
TimeTypeAdmissibility selected = null;
List<String> values = new ArrayList<String>();
while(ttaList.hasNext()) {
TimeTypeAdmissibility tta = ttaList.next();
htmlBuffer.append("<option ");
if (null ==
context.getRequest().getParameter("admissibilityValue_" +
i)) {
if(vo.getAdmissibility().compareTo(tta)==0)
{
htmlBuffer.append("selected='true' ");
}
} else if
(tta.getLabel().equalsIgnoreCase(context.getRequest().getParameter("admissibilityValue_"
+ i))) {
admis.setAttribute("selected", "true");
}
htmlBuffer.append("value='" + tta.getLabel() + "'>"
+tta.getLabel() +
"</option>");
}
return htmlBuffer.toString();
}
});
addColumn(selection);
Any suggestions?
Thank you
