Hi Rajesh,

Here are a couple of snippets including programmer comments from the
BasicSplitPaneUI and as far as I know this hasn't changed much in 1.4,
1.5, or 1.6. I believe the problem is in the BasicSplitPaneUI. I've
always been disappointed with the behaviour of the JSplitPane and I
think you can see from the comments in the code that the programmer
wasn't entirely satisfied either. Have a look at the BasicSplitPaneUI
to see if it gives you any insights to solving the problem you are
experiencing.

   [snip]
   /** Indicates that we have painted once. */
   // This is used by the LayoutManager to determine when it should
use
   // the divider location provided by the JSplitPane. This is used as
there
   // is no way to determine when the layout process has completed.
   boolean             painted;
   [snip]
   if (painted) {
       // This is tricky, there is never a good time for us
       // to push the value to the splitpane, painted appears to
       // the best time to do it. What is really needed is
       // notification that layout has completed.

Cheers,

Dan Andrews
