And that is way I suggested you need to start with an SSCCE.

Create a simple program that does what you need. Prove to yourself that it indeed is only a single line of code that is required to replace a component in a scrollpane.

Then once you get it working in a simple program you look to what is different in your real program. Like I said we don't have time to read through all that code.

maybe adding of mouselistener


Thats easy to check. Just add a println(..) statement in the listener to see if the code is executed.

or anywhere else??


A common problem is having two variable reference different scrollpanes. So maybe you have a class variable and an instance variable of the same name. Get rid of the instance variable.

There is no need to revalidate() the viewport.
