JScrollpane does not work properly when I interlinked to another Scrollpane

Hi,

I am trying to develop a small Editor using java Swing. I hav to display Line numbers also. for that i used another textarea and set the scrollbar model of that to the scrollbar model of text area where i type the programs. the module works perfectly in the first appearance.. scrolls same time..but the problem arises when i insert a new line into or delete a new line from the text area. when i am inserting or deleting the scrollbar of the prgram text area scrolls down immdtly after the insertion or deletion...

I tried a lot to solve the problem. Please help me...
