Two MultiTextNodes in Palette can't be separator!

I need help.See the image below.There is a Palette(JGo Control),in the palette are many MultiTextNodes.Any one can tell how to make the “Random Number” and the lastest

“Comment” node separate,like the “Prompt” and “Menu”?

By the way,i use palette.getDocument().addObjectAttail()

method to add MutliTextNode to Palette.

Thanks all.

I suggest increasing the JGoPalette’s GridHeight a little bit. I’m guessing that the height of the “Random Number” item is almost exactly the same as the view’s GridHeight.
