mapping problems

I am trying to map our .net application

i map it to a point:

NameMapping.Sys.Medcon_Framework_Shell.FrmMain.zpnlFrameworkArea.zpnlNavigationArea.CtlNavigationBar.ultraExplorerBar1.NvPyshSumminfo.UltraTree

but when i try to map its children they dont appear

when recording a script tc records:

Set ultraTree2 = ultraExplorerBar.NvProcdinfo.UltraTree

ultraTree2 = ultraExplorerBar.NvProcdinfo.UltraTree

Call ultraTree2.ClickItemXY("Procedure type", 23, 7)

is there  a way to recognize them or to map a virtual object?

thanks
