>                 Key: WW-3551
>                 URL: https://issues.apache.org/jira/browse/WW-3551
>             Project: Struts 2
>          Issue Type: Bug
>          Components: Other
>    Affects Versions: 2.2.1
>         Environment: JDK 1.5.0_22
> JONAS 4.10.3
>            Reporter: olivier sagit
>            Priority: Minor
>         Attachments: log.txt
>
>   Original Estimate: 0.5h
>  Remaining Estimate: 0.5h
>
> Problem:
> There is a problem with the <s:submit type="image" src=""> taglib in forms.
> While rendering it generates a java.lang.NullPointerException (see attached log.txt for
stacktrace) in debug mode.
> Test:
> To test this behavior you can download the struts2 samples 2.2.1 and modify the form
submit tag in struts2-showcase-2.2.1/conversion/enterPersonsInfo.jsp to be a submit of type
image.
> Diagnosis:
> This trace is produces by the presence of the freemarker property <@s.property value="parameters.body"/>
in template/simple/submit.ftl.
> Solution: 
> As seen with Maurizio Cucchiara on Struts (Users/Dev) Mailing list, this body parameter
would seem unnecessary, so is a good candidate for removal, though it don't cause any side
effect (except for the exception in debug mode).
