Johno Crawford commented on WW-4241:
------------------------------------
Close as won't fix? The answer in stackoverflow sums it up nicely. "Actually it
is very simple: Arabic is right to left script. So your -1 is actually 1- (and
a String) you need to input 1- to post negative integers."

> Negative integers are giving OGNL error setting expression when submitted
> through form post or query string ONLY when the language is arabic. For all
> other languages the form works fine & no OGNL errors. The negative integer
> value is perfectly received at the action side.
> I have also posted the question in very detail here :
> http://stackoverflow.com/questions/19875848/query-string-urls-behave-incorrectly-after-the-language-is-changed
> The SSCCE to demonstrate this bug is available here
> https://dl.dropboxusercontent.com/u/109241721/Struts2Example.zip
> username is an integer, it accepts both positive & negative integers when not
> using arabic language, but as soon as language is changed to arabic, it
> doesn't accept negative integers and start throwing OGNL exceptions for error
> setting expression.
> You guys can reach me at nitin.cool4urc...@gmail.com for any more information
