Users can change URL adding parameters, modifying values, removing other parameters, etc. So, I think that it could but probably is not the best way to go. Threating these convertions with checked exceptions give us (programmers) a rule to follow: "please, check parameters and alert user if he/she sent invalid values."
My vote? Keep it checked.

Hi all,
I was looking at the code for PageParameters and then StringValue in 1.2.1
StringValue is throwing a checked exception
StringValueConversionException for string converted to another type.
While I understand the motivation, it seems to me it would remove some
slight handling annoyance by putting it as an unchecked (ie: runtime)
exception.
Strictly speaking if such thing happen this is due to a mistake by
storing invalid types and therefore there is very little chance it to
recover from it in any sort of way. So you basically won't be able to do
anything worth it with the checked exception.
If however someone is doing some clever trick and handling multiple
types in a strange way, then I guess, it makes sense for this person to
try/catch unchecked exception and try to recover by asking another type,
etc...
So I'm voting to have StringValueConversionException extends
RuntimeException instead of Exception :)
Maybe I have missed something obvious though.
WDYT ?
