Fix Version/s: 2.0.14
Copy conversion errors from fake stack into the real one
> Struts 2.0.12 has broken Conversion Errors
> ------------------------------------------
>
> Key: WW-2853
> URL: https://issues.apache.org/struts/browse/WW-2853
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.12
> Environment: Windows XP - JBOSS 4.2.2
> Reporter: David Harland
> Fix For: 2.0.14
>
>
> Since upgrading to struts 2.0.12 from 2.0.11.1 all conversion errors are
> being lost.
> Here is a simple example showing this is broken!
> Take the Struts2 blank app for 2.0.11.1. Now add a simple Action with an
> Integer property testNumber. Now add a jsp with a field testNumber. Now put
> fred in testNumber and submit.
> You get 'Invalid field value for field "testNumber".'
> Now replace the lib files from the 2.0.11.1 struts2 blank with the 2.0.12.
> The Conversion errors now do not get displayed. They are lost!
> It appears to be the ParametersInterceptor is taking a copy of the
> ValueStack, the conversion errors are being set on the new stack and
> therefore lost.
>
> Regards
>
> David.
