Looks like you're trying to use a ProgressBar as a CellRenderer. One thing you should know, is that CellRenders are only called when a cell is being drawn, and setting values at other moments has no effect: this is because Swing uses a flyweight pattern for renderers, and thus reuses the renderer.

To get the effect you want, you should

• notify the table that the cell is to be updated, for instance by updating its underlying model (that will fire the necessary events), and
• set all values you need before the getTableCellRendererComponent return, so, remove the invokeLater (the getter is called on the EDT, so you don't need to worry about threading there).
