Javascript JS中的应用程序项值使用 &APP_ITEM.

但是不能在Javascript中设置值应用程序项。您必须创建一个将设置应用程序项值的进程，并从Javascript apex Ajax调用该进程

<script>
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=SET_APS_CASEIDS',0);

get.addParam('x01',$caseIds);

gReturn = get.get();
if (gReturn) {
window.location='f?p=&APP_ID.:66:&SESSION.::NO:66';
}
</script>

从共享组件创建应用程序进程

Name: APS_CASEIDS
Session State protection:unrestricted

Name:SET_APS_CASEIDS (Name should be match in ajax call).
Process point:On Demand:run this application process when requested by process.
Process Text:
