Strange, for me
dictionary.getobject(objFullname)
requieres a second boolean parameter == false to avoid non-existant object
error... :
dictionary.getobject(objFullname, False)
but maybe VB and jscript are different on that point ?
Also make sure you use obj.FullName and not obj.Name when working with models
and children
