Subject [jira] Commented: (WW-3119) Stringlength validation problem for utf-8 chars (Struts 2.1.6)

Wes Wannemacher commented on WW-3119:

Qunhuan Mei, 

In fact, you can access the struts 2.1.7 snapshot code here -

If you don't mind testing this with the snapshots at the above URL, that would be great.

> When I try to validate utf-8 chars such as Chinese using Struts 2.1.6, the stringlength
validation appears to have problem. It seems the validation process is not using the number
of Chinese chars before encoding, but rather the number of chars after encoding. The following
are the steps to reproduce the problem:
> 1.	Create a project by importing struts2-blank-2.1.6.war from ...\struts-2.1.6\apps"

> and make the login.jsp work with, e.g. print out the username.length() in
setUsername(...) function.
> 2.	copy the following stringlength validation code into Login-validation.xml:
> <field-validator type="stringlength">
>         	<param name="maxLength">4</param>
>         	<param name="trim">true</param>
>         	<message key="fieldNameShouldBeWithinMaxLength"/>        	
> </field-validator>
> 3.	copy the following stringlength error message into
> fieldNameShouldBeWithinMaxLength=The max number of chars of ${getText(fieldName)} is
> 4.	run the login.jsp and type in either "abcd" and "abcde" into username, we can see
that "abcd" does not incur a validation message whereas "abcde" does.
> 5.	now typing 2 Chinese chars, say "世界"into the user name, which should not have
any problem since only 2 chars. However the struts reports the chars received are more than
4. As a matter of fact, the print out statement in setUsername(...) reports the number of
chars is 6.

> BTW: is there any way to access the validation code from struts 2.1.7 (this bug may have
been fixed by the 2.1.7 code)? Thanks.
