Problem with listbox selectedItem at the page creation

 <listbox id="companyListbox" width="100px" model="@{composer.companyModel}" mold="select" >
                    <listitem self="@{each=companyData}">
                        <listcell label="@{companyData.company.name}" />
                    </listitem>
                </listbox>

@Override
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);
        DataBinder binder = new AnnotateDataBinder(comp);
        binder.bindBean("composer", this);
        binder.loadAll();
    }
