Kumar,
I ran following (copied from your code) and it is showing me the value for
memberNumber. No NPE. Since you have String as memberID, I have assigned
String type to the models and property variable.
PropertyModel<String> memberIdModel=new
PropertyModel<String>(this,"memberNumber");
TextField<String> memberIdField = new
TextField<String>("memberId",memberIdModel);
Form<?> form = new Form<Void>("form"){
/**
*
*/
private static final long serialVersionUID = 1L;
/* (non-Javadoc)
* @see org.apache.wicket.markup.html.form.Form#onSubmit()
*/
@Override
protected void onSubmit() {
System.out.println(memberNumber.equals("5566"));
}
};
add(form);
As Sven has mentioned, stacktrace might be more helpful.
