Hi,

Wicket will refocus the textField after replacing the markup tag.

Sorry, I don't understand that.

I am understanding how to handle JS events like onfocus and onblur in apache
wicket. I have a simple form in which there is a textfield. "onfocus" event
on this I am trying to set the textfield to a value. I have observed on
running the code that onfocus is called again and again (recursively it
seems). I fail to understand why and what I have done wrong. Below is the
code :
HTML:
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org";>
<head>
<title>Wicket Examples - component reference</title>
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<form wicket:id="form">
<INPUT wicket:id="input" type="text" name="input" style="WIDTH: 800px"
/>
</form>
Java:
package com.poc.pages;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.form.AjaxFormComponentUpdatingBehavior;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.form.ChoiceRenderer;
import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.model.Model;
public class IndexPage extends WebPage
{
/**
* Constructor
*/
public IndexPage()
{
Form form = new Form("form");
TextField<String> TextInput = new
TextField<String>("input",Model.of(""));
TextInput.add(new AjaxFormComponentUpdatingBehavior("onfocus"){
@Override
protected void onUpdate(AjaxRequestTarget target) {
String thisValue =
this.getComponent().getDefaultModelObjectAsString();
thisValue = "ChangedNormally";
this.getComponent().setDefaultModelObject("ChangedViaDefaultSetModel");
target.add(this.getComponent());
System.out.println("onfocus"+thisValue);
}
});
form.add(TextInput);
add(form);
}
}
When I focus on textfield here, ChangedViaDefaultSetModel is set and on
console onfocusChangedNormally gets print continuously. I fail to undertsand
few things :
Why does onfocus gets called again and again printing onfocusChangedNormally
evertytime on console?
How can I get the value of actual model and not default model.
WHy does the normal value doesnot get reflected in model whereas on doing
setDefaultModel() it works?
Thanks For Help
