我正在尝试从支持bean打开一个对话框，但我得到了：未捕获的TypeError：无法读取未定义的属性'show'
这是我从bean调用对话框的代码：
RequestContext.getCurrentInstance().update("someForm:confirmDialog");
context.execute("PF('confirmDialog').show()");
这是我的支持bean的一部分：
@SuppressWarnings("serial")
@ManagedBean
@ViewScoped
public class SomeBean implements Serializable{
private String something = "";
private ObjectCast newDefault = null;
private List<SomeObject> list = null;
public void onEdit(RowEditEvent event) {
newDefault = (ObjectCast)event.getObject();
if( newDefault.getDefault().equals("X") ){
RequestContext context = RequestContext.getCurrentInstance();
RequestContext.getCurrentInstance().update("someForm:confirmDialog");
context.execute("PF('confirmDialog').show()");
}
public void updateNewDefault(){
... do something...
}
.... getters and setters ...
}
