In order to speed up an application it is possible to group two or more actions into one Page Engine request, using uwa.groupRequests()". For example:
All function calls within uwa.groupsrequests() are sent to the server in one request and executed sequentially. uwa.groupRequests() can be seen as the dynamic version of handleEvent (StaticEvent).
Note: The default Web application does not use "uwa.groupRequests()". Only "executeQuery" bundles the actions "getRecordCount(..)" and "getDataSet(..)" but it does this without using this function.
