保存和取消 mxevent IBM Maximo

如何解决保存和取消 mxevent IBM Maximo

我有一个 texBox 字段，想在对话框中更改它的值。怎么做这个对话不保存我的价值和对话保存我的价值？

 <dialog id="XOratingBRANDPOPUP" label="chancge value">
<textBox dataattribute="ratingBRAND" id="maintab_attr19" />
    <buttongroup id="bookmarks_11">
        <pushbutton default="true" id="bookmarks_3_1asd" label="Ok" mxevent="dialogok"/>
        <pushbutton default="true" id="bookmarks_2_1asd" label="Cancel" mxevent="dialogcancel"/>
    </buttongroup>
</dialog>

我尝试添加类

public class XoCarsAppBens extends AppBean {
public XoCarsAppBens() {
}

public int CUSTOMDIALOGCANCEL() throws remoteexception,mxexception {

    MboRemote thisMbo = this.getMbo();

    thisMbo.setValue("ratingBRAND",thisMbo.getDatabaseValue("ratingBRAND").toString());
    this.clientSession.queueEvent(new WebClientEvent("dialogcancel",this.app.getCurrentPageId(),null,this.clientSession));
    return EVENT_HANDLED;
}

}

但它不起作用
