> URL: http://issues.apache.org/jira/browse/TAPESTRY-847
> Project: Tapestry
> Issue Type: Bug
> Components: Framework
> Affects Versions: 4.0
> Reporter: Chris Conrad
> Fix For: 4.1

>
> I have a text field on a form into which a user is supposed to enter a number
> within a certain range. So I added the max and min validators to the text
> field hoping they would do what they're supposed to do. Unfortunately, a
> user quickly discovered that if they don't follow the instructions and enter
> a letter into that text field they get an ugly NumberFormatException. I
> poked around a little and found that I can't even catch that exception to
> present something nicer to the user because my listener method never even
> gets called. So, it would be extremely useful if the numerical related
> validators caught NumberFormatException and provided a "The value must a be
> number" error message.
> In this particular case, using any kind of drop down or selection box widget
> wouldn't work because the number range is quite large (basically from 0 to
> several million).
