JSplitPane and initial Divider Locaation problem

Hello,

I am having trouble with setting the initial size of a JSplitPane and was
wondering if any of you had run into this and possibly solved it.

Behavior:
in the jbInit() I do the following:
1) Add everything to two panels (pnlTop and pnlBottom).
2) Create the SplitPane like so:
splitter = new JSplitPane(JSplitPane.VERTICAL_SPLIT, pnlTop, pnlBottom);
3) Then I try to do this:
splitter.setDividerLocation((double)0.70);
splitter.setOneTouchExpandable(true);
splitter.setDividerSize(6);
4) Then I try a repaint() before I show the application.

When the application starts the splitter is at DividerLocation(0.0) - the
very top.  I can click on the splitter once and it jumps to the place it
should have been (just below the middle of the window).

The _only_ way I can get the (*&!@$# splitter to kind of show up in the
correct place is to  add a   this_componentShown(ComponentEvent e)  and do
this in the body of the method:
app.splitter.setDividerLocation(0.70);
where app is a reference to the mainapp where the reference to splitter
lives.

This does kind of work, but the app is shown and then the bar jumps down to
it's correct position - making things look very sloppy.

So the questions:
1) Why does
splitter.setDividerLocation((double)0.70);
_not_ work while
app.splitter.setDividerLocation((double)0.70);
_does_ work in a stupid componentShown event?

And
2) How can I get the splitter to behave and set it's position correctly
before it's painted on screen?

TIA,
Jeff Carlson
