in the above replace

by 
&nbsp; &nbsp; &nbsp;Component c = e.getComponent();

in the above replace
     Component c = e.getSource();
by

I have the following: 
 
private boolean firstTime = true; 
 
&nbsp; &nbsp; // only for initial visuals and selections 
&nbsp; &nbsp; this.addComponentListener(new ComponentListener() 
&nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; public void componentResized(ComponentEvent e) 
&nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; } 
&nbsp; &nbsp; &nbsp; public void componentMoved(ComponentEvent e) 
&nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; } 
&nbsp; &nbsp; &nbsp; public void componentHidden(ComponentEvent e) 
&nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; } 
 
&nbsp; &nbsp; &nbsp; public void componentShown(ComponentEvent e) 
&nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; &nbsp; if (firstTime) 
&nbsp; &nbsp; &nbsp; &nbsp; { 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //tree.clearSelection(); 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; firstTime = false; 
&nbsp; &nbsp; &nbsp; &nbsp; } 
&nbsp; &nbsp; &nbsp; } 
&nbsp; &nbsp; }); 
 
once the action has been performed once i want to remove the action - but of course i cant do &nbsp; &nbsp; this.removeActionLi... &nbsp;from inside the listener itself!!

Remove a once-off listener

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
