Hi,
Some of my application users are complaining about seeing NumberFormatException when they try to clcik a button. I asked one of them to take a picture for me, and it turns out the error message is from a checkbox! As I know, not every user will encounter this problem, and I couldn’t reproduce this error message either. Here is the image that shows the error. Please look at my code for this window. Basically, the next button is disabled by default. User needs to click the checkbox to proceed.
PS. Vaadin is 6.8.9, Tomcat 7.0.3x
