Hi
I'm currently facing the problem where child nodes beyond second level do not expand. The issue lies with the elements not binding to the parent node from which they have been expanded. The various combinations that have tried either resulted one of these:
a) All child elements expanding under the first node.
b) With initial lead selection led to 'false' and on selecting the node first and then clicking expanding, the child elements get filled up in the node, but on clicking the child nodes below it. It starts filling the node which is lead selected.
c) If I expand the tree based on the index of element, it doesn't expand beyond the second level and throws index exception.
Following is the code mentioning :
public void addChildren( essent.nl.sp.wdp.IPrivateZSPAllSitesStartView.ITreeSiteDirectoryElement element )
{
//@@begin addChildren()
IWDMessageManager manager = wdComponentAPI.getMessageManager();

// IPublicZSPAllSitesComp.ITreeSiteDirectoryNode TreeSiteDirectoryNode = element.node().getNodeIn;
IPublicZSPAllSitesComp.ITreeSiteDirectoryNode ChildTreeSiteDirectoryNode = wdContext.nodeTreeSiteDirectory();
IPublicZSPAllSitesComp.ITreeSiteDirectoryElement ChildTreeSiteDirectoryElement = null;
// IPublicZSPAllSitesComp.ITreeSiteDirectoryElement InnerChildTreeEle1, InnerChildTreeEle2 = null;
Vector table = new Vector();
Vector line = null;
try
{
String busServer = element.getServer();
// HashMap hashMapCache = new HashMap();
// Object oHashMapCache = hashMapCache.get("ZSharepointSites"+busServer);
// ICacheService cache = (ICacheService)WDPortalUtils.getServiceReference("com.sap.portal.compatibility50.cache");//use of this reference
// Object vectorcache = cache.get("ZSharePointSites" + busServer);
