[jira] Commented: (TAPESTRY-795) Client-side validation of numbers doesn't allow punctuation

Leonardo Quijano Vincenzi commented on TAPESTRY-795:
----------------------------------------------------

I implemented a parseLocalizedNumber() Javascript method in Tacos (the file helper_functions.js) that could work for this. Is based on Dojo, though, but if anyone's interested, he can port it over to Tapestry 4.0.

> Client side input validation assumes that numbers can be validated using isNaN(), which knows nothing about punctiation:  1,000,000 is a valid number that will be rejected.
> Further, on the server side, this value will not be handled correctly; if the translator's pattern is "#" (the default), this value is truncated to "1" rather than it being an input error.  In any case, the client and the server should support grouping characters as defined by the active locale.
