You create trees using the treeView() dialog and the insert() function to add things to the tree.
The important thing to note is the database separator (which is just a forward slash, or you can use the constant "dbSep" in DXL) is used as a delimiter. So when you insert something in the tree, for example an object tree, you need to insert it as
insert("/" identifier(obj) "/" identifier(otherObj))
This tells DXL that obj is a branch with otherObj as a leaf of the branch.
If will take a little experimenting to get the hang of, but it work fine once you do.
