Exception in thread "AWT-EventQueue-0" error

[Shaun Seah]

Hi guys, I am having difficulty trying to debug this exception....

My swing apps, retrieves record from Database and is wrapped by a TableModel.
Finally this is passed into a JTable.

Finally this app is multi-thread, meaning it can accept multiple database queries and repaint the same Jtable once the query is completed.

please help. thanks.

Did you go through the tutorial on Concurrency in Swing that I recommended in your earlier thread? Or did you just never return to that thread to read the response there?

Hi Darryl,

Am still working on the previous thread...i didn't think this issue was related to my previous query.
Sorry for the double post.

thanks

My reason for asking is that this issue also looks like being related to concurrency and not abiding by Swing's single threaded rule.
