I tried disabling the button during the event and while this was easy enough to implement it did not help. My page contains a table which has panels in different cells. I swap these panels in and out depending on wether the user is in 'edit' mode or 'submit' mode and also according to where they are in the workflow. I noticed that the method of PropertyColumn which I am overriding populateItem(Item item, String componentId, IModel model) completes, as does the event handling code at the button press so I am not sure what is breaking down. It's easy to reproduce this error. All I have to do is to click a button which is present in one of the panels rapidly, at every click I do toggle the name of the button from "edit" to "save" so I don't know if this has something to do with it. I do need this problem resolved because this is not acceptable for a production application. I would really appreciate any ideas that you have.
