Hello All,
I'm building an application that loads records from a database and presents them in a JTable. All seems to work ok, but sometimes the following error is diplayed:

java.lang.ArrayIndexOutOfBoundsException: 6 >= 1
at java.util.Vector.elementAt(Unknown Source)
at javax.swing.table.DefaultTableColumnModel.getColumn(Unknown Source)
at suncertify.client.RoomsTableColumnModel.getColumn(RoomsTableColumnModel.java:48)
at javax.swing.plaf.basic.BasicTableUI.paintCells(Unknown Source)
at javax.swing.plaf.basic.BasicTableUI.paint(Unknown Source)
at javax.swing.plaf.ComponentUI.update(Unknown Source)
at javax.swing.JComponent.paintComponent(Unknown Source)

at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)


It's strange because sometimes it's displayed, and sometimes not. I can't identify what is causing the problem, since it happens without any change. Does anyone knows what is going on?

Regards,
Flavio.

Are your columns dynamically generated? It looks like the code thinks there are 6 columns, when really there is only 1...

For a better answer, you'd need to post the relevant code from your "RoomsTableColumnModel"...
