Hi Martin
Thanks for looking at this. It's a bit complicated because we've built a
form framework around Wicket, but here goes:
In the page:
HtFormPanel.DateFormField startField = new
HtFormPanel.DateFormField("startField",
new StringResourceModel("start", this, null), new PropertyModel<Date>(this,
"start"), false);
Where the constructor for HtFormPanel.DateFormField is:
public DateFormField(String uniqueId, IModel<String> label, IModel m,
boolean bShowTime)
{
// The DateTimeField is contained within the DateFormField
super(uniqueId, FieldType.DATETEXTFIELD.toString(),
(bShowTime ? new DateTimeField(FIELD_ID) :
new DateField(FIELD_ID)), label, m);
}
Next, in the page:
startField.setFieldOutputMarkupId(true);
// The radio button that does the ajax update:
final HtFormPanel.RadioFormField<ReportAction> actionField = new
HtFormPanel.RadioFormField<ReportAction>(
"actionField",new ResourceModel("actionField"),actionTypes,new
LocalizedChoiceRenderer<ReportAction>(this),
new PropertyModel<ReportAction>(this,"action"));
Finally, the update code that causes the problem:
actionField.getFormComponent().add(
new HtAjaxFormChoiceComponentUpdatingBehavior() {
private static final long serialVersionUID = 8574977146235850631L;
protected void onUpdate(AjaxRequestTarget target) {
if (getAction() != null
&& getAction().equals(ReportAction.VIEW)) {
startField.setRequired(false);
} else {
startField.setRequired(true);
}
// We update the startField and the DateTimeField inside it.
target.addComponent(startField);
target.addComponent(startField.getComponent());
}
});
