5. Re: Components migration:change a4j:keepAlive to JSF 2 view scope
Thank you, I have solved the problem. Like this:
...
@ManagedBean
@ViewScoped
public class SysMenuBean extends BasePage implements Serializable {
...
public SysMenuBean() {
this.sysMenuManager = (SysMenuManager) this
.getManagerObject("sysMenuManager");
this.sysCodeManager = (SysCodeManager) this
.getManagerObject("sysCodeManager");
String id = this.getRequestParameterMap("id");
if (id != null) {
sysMenu = this.sysMenuManager.get(id);
}
}
...
In the constructor to initialize the object, so that you can modify, thank you very much.
非常感谢
