How to access attributes of an instance?

Question

For example, I declared an instance of a CustomNode class "workspaceRow".
     Group{
         translateX: 50
         translateY: bind (wsY * -1) + (i*25);
         content:[
                 workspaceRow{
                      lineNumber: i.toString();
                    myColor: theColor;
                    onMouseEntered: function( e: MouseEvent ): Void {
                        selectedRow = i.toString();                  
     }How do I access lineNumber? I'm trying to use it for the onMouseEntered function inside the workspaceRow (as seen above), but Eclipse says it cannot find lineNumber, because it's looking for it at the top of the hierarchy (as in, looking for lineNumber declaration on my main *.fx file, instead of inside the instance). It's because I need to be able to store some data inside, and retrieve it later on.

Answer 1

For that lineNumber thing, sorry about that. I was trying to access it in the onMouseEntered function, but decided to use var "i" instead, since it was what I used to generate a loop, and I use that same variable for lineNumber, but I know it'll give me problems later on.
Yeah, forgot about capitalized class names, and yes, WorkspaceRow is a class extending CustomNode.
Thanks a lot, your way worked. I am just wondering though, why doesn't JavaFX want to put the declaration and instantiation of the node inside Group{}? When I move those code blocks inside, Eclipse highlights the line "Group{" and says "unexpected type required: variable found : value".
If I proceed with initializing the instance right on the declaration inside Group{}, it says "This is the type of cyclic reference to workspaceRowNow that prevents type inference.". As in like this:
          var workspaceRowNode = WorkspaceRow{
                 lineNumber: i.toString();
               myColor: theColor;
               onMouseEntered: function( e: MouseEvent ): Void {
                   selectedRow = i.toString();
                   print(workspaceRowNode.lineNumber);                  
          }Can anyone explain what that means?
