Retrieving property Error when rendering submit of type image in debug mode
---------------------------------------------------------------------------
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
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).
