I have this custom CanvasItem that I'd like to have validate when form.validate() is called. I tried overloading validate (see below), but it doesn't seem to be called. Any suggestions?
Thanks.

Code:

private IntegerItem daysField;
private TimeItem timeField;
private DynamicForm form;
public DelayTimeItem(String name, String title){
super(name, title);
final ChangedHandler handler = new ChangedHandler(){

if(daysField.getValue() instanceof Integer && timeField.getValue() instanceof Date){
storeValue(convertValue());
}
}
private long convertValue() {
long minutes = 0;
Integer days = (Integer) daysField.getValue();
Date time = (Date) timeField.getValue();
if(days != null) {
minutes += days * 24 * 60;
}
if(time != null) {
minutes = time.getHours() * 60 + time.getMinutes();
}
return minutes;
}
};
daysField = new IntegerItem("days"){{
setWidth(48);
setShowTitle(false);
addChangedHandler(handler);
}};
timeField = new TimeItem("time"){{
setWidth(64);
setShowTitle(false);
addChangedHandler(handler);
}};
form = new DynamicForm(){{
setFields(daysField, new StaticTextItem(){{
setShowTitle(false);
setContents("days");
}}, timeField);
setNumCols(3);
}};
setCanvas(form);
addShowValueHandler(new ShowValueHandler() {
@Override
public void onShowValue(ShowValueEvent event) {
Integer value = (Integer) event.getDataValue();
if(value != null){
long days = value / (24 * 60);
long minutes = value % (24 * 60);
daysField.setValue(days);
timeField.setValue(minutes / 60 + ":" + minutes % 60);
}
}
});
}
@Override
public Boolean validate() {
return super.validate() && daysField.validate() && timeField.validate();
}
}
