Bug 49950

This can be reproduced if, while recording, selecting a row in a recently recorded http sampler's parameter table and than performing another http action.

That's the table the ObjectTableModel that creates the exception is linked to.

Except from the exception appearing in the console output, I don't see any other problems.

Hello,
Can you make screenshots of your bug scenario ?
I am not sure to understand:
"selecting a row in a recently recorded http sampler's parameter table and than performing another http action."

Thank you
Regards

Scenario is the following:
- Configure Proxy and Recording Controller
- Start recording gmail for example
- Click on gmail link and while it is loading, select a node under Recording Controller you will get this exception in logs:

All these issues are due to update of TableModel from other threads than AWT Thread.
