[jira] [Updated] (WICKET-6168) NULL Object Model in Radio Group

     [ https://issues.apache.org/jira/browse/WICKET-6168?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Anton Kurniawan updated WICKET-6168:
------------------------------------
    Description: 
Creating project use (http://wicket.apache.org/start/quickstart.html):
{code}
mvn archetype:generate -DarchetypeGroupId=org.apache.wicket -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=7.3.0 -DgroupId=com.mycompany -DartifactId=myproject -DarchetypeRepository=https://repository.apache.org/ -DinteractiveMode=false
{code}

Change java version:
{code}
:
<plugin>
:
<plugin>
	<inherited>true</inherited>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
	<version>3.1</version>
	<configuration>
		*<source>1.8</source>*
		*<target>1.8</target>*
		<encoding>UTF-8</encoding>
:
{code}

Add a field:
{code}
private final IModel<String> stringModel = new Model<>("AAAAAAAAAAAAAAAAA");
{code}

Add some codes in constructor {{Home.java}}:
{code}
/*RADIO GROUP TEST*/
callMe();

final Form<Void> form = new Form<>("form");
form.add(new RadioGroup<>("stringRg", stringModel));

form.add(new AjaxButton("btnTest") {
	@Override
	protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
		super.onSubmit(target, form);
		callMe();
	}
});
add(form);
/*END OF RADIO GROUP TEST*/
{code}

And in HTML:
{code}
<!-- TEST RADIO GROUP -->
<form wicket:id="form">
	<div wicket:id="stringRg"></div>
	<button wicket:id="btnTest">TEST</button>
</form>
<!-- END OF TEST RADIO GROUP -->
{code}

Add mymethod in {{Home.java}}:
{code}
private void callMe() {
		System.out.println(String.format("String object: %s", stringModel.getObject()));
	}
{code}

The output:
{code}
String object: AAAAAAAAAAAAAAAAA --> called by constructor
String object: null --> called by {button test}}
{code}
