Robert McGuinness commented on WICKET-4356:
-------------------------------------------
i ran into this issue as well, kinda wish the api would fail silently upon
conversion and return defaults. Ex:
http://wicket-stateless.herokuapp.com/?counter=8 (works)
but I forgot to check for non ints so the following will fail (will be fixed
soon)
http://wicket-stateless.herokuapp.com/?counter=fails
> StringValueConversionException thrown when calling toInt(final int
> defaultValue) on StringValue. Why not to return the default value?

> Issue Type: Improvement
> Components: wicket
> Affects Versions: 1.5.3
> Reporter: Sergei Sizov

> In my application I need to get current page parameter from PageParameters
> so I use this code
> PageParameters parameters = ...
> int currentPage = parameters.get("page").toInt(1);
> It works good when "page" parameter contains an Integer value or is null, but
> when it contains a non numeric value it throws an exception
> StringValueConversionException.
> I would expect a little bit different behaviour. Why not to return DEFAULT
> value when StringValueConversionException is thrown? I think it is more
> secure and saves many lines of code, because you do not need to check that
> StringValue is really a string containing only numeric characters.
