Hi,

I have a testprogram that get data from a JDataStore and build a tree 
from that.

As the root is the CEO in the organization. I have a list of CEOs in my 
database and place them in a jComboBox. I have added an actionperformed 
trigger to my ComboBox so that if a new CEO is selected I want to clear 
out the tree (created in jbInit) and build a new one with new data from 
my DB.

I just can't find a way to empty the tree.

Any help and/or pointers to this is appreciated.

Magnus

PS. I have got most of my help so far from:

I got it to work

I thought I could work with the Tree but realized that I need to work 
with the root node and the TreeModel.
