you must add the component you want to update to the target in onSubmit
method, like this:
target.addComponent(filterPanelMsgLabel);
The code, tells to wicket which component to update on ajax request.

Hi to all,
I want to display one label when I click one button.
I have wrote the code. but i am not able to display that message.
my code is looking like
file name : FilterPanel.java
public final class ReportForm extends Form
{
public ReportForm(String s, final Reports model)
{
super(s);
setOutputMarkupId(true);
PropertyModel filterPanelMsgModel = new PropertyModel(this,
"validationMessage");
final Label filterPanelMsgLabel = new
Label("validationMsgLabel",
filterPanelMsgModel);
filterPanelMsgLabel.setEscapeModelStrings(false);
filterPanelMsgLabel.setOutputMarkupId(true);
add(filterPanelMsgLabel);
//in submit button,
AjaxSubmitLink saveButton = new AjaxSubmitLink("saveButton", this)
{
protected void onSubmit(AjaxRequestTarget target, Form form)
{
// To display the string in html page.
setValidationMessage("Please enter valid date");
}
}
//getter and setter methods
private String validationMessage ="";
public String getValidationMessage() {
return validationMessage;
}
public void setValidationMessage(String validationMessage) {
this.validationMessage = validationMessage;
}
in FilterPanel.html
