1) There is VO called Transaction - which are added to collection - and collection is returned via getCurrentTrans
2) Transaction VO has member of type ITreeContentProvider - i.e each Transaction (row in a html view) has a tree
3) I am able to display roots exception below is generated when plus sign is clicked
>> what gets invoked when plus sign is clicked - I thought it was getChildren on Folder
Thanks
