Subject [jira] Commented: (WW-2254) Stringlength validator xhtml template should be locale independent
Date Tue, 12 Feb 2008 06:41:39 GMT


Wes Wannemacher commented on WW-2254:

A better approach would be to use the freemarker built-in c, as documented here - So it should look like
${validator.maxLength?c}. If/when I get a chance I'll look through the freemarker files for
instances where this is appropriate.

> The freemarker template that generates client side validation for the xhtml theme (template/xhtml/form-close-validate.ftl)
generates the javascript functions for different validators.
> In the case of the stringlength validator there are a series of lines of code that are
generated that may not work in locales that are not English. For example, if you define the
maxLength to be 1000.
> value.length > ${validator.maxLength}
> in a Spanish locale outputs
> value.length > 1,000
> Which results in a string comparison rather than a number comparison.
> The solution that i've found is to force the formatting of maxLength and minLength in
freemarker using ?string("#"). For example
> value.length >  ${validator.maxLength?string("#")
> Which outputs the correct version.
> value.length > 1000
> I believe that all references to maxLength and minLength in form-close-validate.ft should
use this. I haven't looked to see if there are other places in the file where a similar error
could occur.
