write this code in clicked method of button or menuitembutton:
 http://abjbaskar.wordpress.com/2011/08/12/parent-shold-not-be-closed-unless-child-form-is-closed/
Args args;
FormRun formRun;
;
super();
args = new Args(formstr(ChildFormName));
args.caller(element);

formRun = classFactory.formRunClass(args);
formRun.init();
formRun.run();
formRun.wait(); // to wait the child form to close..

// formRun.detach(); // dont wait the child form to close..
