获取LOV事件

if (pageContext.isLovEvent()) { // Form was submitted because the user selected // a value from the LOV modal window, // or because the user tabbed out of the LOV input. // Find out which LOV input triggered the event. String lovInputSourceId = pageContext.getLovInputSourceId();//取当前触发事件的LOV // At this point, all the data is available in the base VO, just as in // regular PPR events. Invoke an AM method to update the application // properties VO. // //获取特定LOV事件  if ("myLovInput".equals(lovInputSourceId))  {  am.invokeMethod("handleMyLovInputEvent");  } } The pageContext.isLovEvent method returns true if the event value is LOV_UPDATE (meaning the user selected a value from the LOV modal window), or LOV_VALIDATE (meaning the user tabbed out of the LOV input field on the base page).
