p:dataTable rowEdit不更新行对象 [英] p:dataTable rowEdit doesn't update row object

问题描述

我正在尝试使用rowEdit模式编辑数据表上的行，但对我而言不起作用.

I'm trying to edit rows on datatable using rowEdit mode but it doesn't work for me.

这是rowEdit事件:

Here is the rowEdit event :

<p:ajax event="rowEdit"
        listener="#{saisirHeuresForm.updateMyRow}" 
        update=":saisirHeuresForm:messages"/>

和managedBean对应的方法:

And the managedBean corresponding method :

public void updateMyRow(RowEditEvent event) {
    event.getObject();
}

event.getObject()方法返回与已编辑但未进行任何属性修改的行相对应的对象.

The event.getObject() method returns the object corresponding to the row which is edited but without any property modification.

有人对这个问题有任何想法吗?

Has someone any idea about this problem ?

推荐答案

最后，我发现我做错了什么.方法getListItems()一直在从DB加载，因此我修改的项目直接从DB重新加载，在这种情况下，无需修改.

Finally I found what I did wrong. The method getListItems() was all the time loading from DB so the items I modified were directly reloaded from DB and in this case, without the modifcation I did.
