JTree in JScrollPane not resizing after model change.

Question

I have a JTree in a JScrollPane that's put in a JPanel using the JGoodies FormLayout as it's layout manager. The column definition defines the column to grow so the JScrollPane should have enough space. The tree is empty when I create it and put it in the JScrollPane.
After adding some nodes to the tree the JScrollPane does not resize automatically, it only resizes when a forced repaint occurs (moving or resizing the window , etc).
I've tried calling invalidate(), repaint(),revalidate() on both the JTree and the JScrollPane. I also do a reload() on the TreeModel after adding the nodes (which is probably unnecessary as I use insertNodeInto(node,parent,position) from the DefaultTreeModel to add the new nodes).
Anybody knows what I'm missing here?
Thanks a lot in advance !

Update:
The card is running now. I had another Arch system (arch2) on the same network (to compare with), and after I shut that down and rebooted the first one (arch1) the network interfaces show up, both lo and eth0.
However, the startup routine hangs about 2-3 minutes on the network daemon (with blinking router lights and hdd activity), so it's still not perfect. Another thing is that I can't get the right gateway from the router's dhcp. Here's an overview of the setup:
Home: 192.168.2.x
arch1 .2.102-------|
|
arch2 .2.101-------| old SMC router: .2.1
|
fritzbox .2.2 -----|
router/modem
|
|
~~~~~
internet
The gateway is supposed to be the fritzbox with ip 192.168.2.2. The old SMC router serves addresses in the range .2.101-110. I set it up this way because I need the 8 ports on the SMC (and I like watching the lights).
Here's my /etc/rc.conf for both systems:
arch1 (starts slow):
eth0="dhcp"
ROUTES=(!gateway)
arch2 (working):
eth0="eth0 192.168.2.101 netmask 255.255.255.0 broadcast 192.168.2.255"
gateway="default gw 192.168.2.2"
ROUTES=(gateway)
arch1 gets the SMC as gateway, arch2 gets the fritzbox.
Ideally all computers on the network should get their IPs from the SMC dhcp, which also gives them the fritzbox as gateway. But that just doesn't work for the arch1. arch2 and the windows PCs get online just fine.
I had also tried setting arch1 the same as arch2 except for the ip=2.102. Then the network starts faster, but the gateway is still stuck at the SMC router -> no internet.
Rather complicated, but what are networks for? Anyone see daylight in this mess?
