> As a developer, I write long JSPs and sometimes I make mistakes. For example, i can write the line underneath:
> {code:xml}
> <s:if test="ghamRestitution.moraHalfFoodFree">blah</s:if>
> {code}
> if the the field "moraHalfFoodFree" doesn't exists on bean "ghamRestitution", XWork raise a warn such as:
> {quote}
> 2014/11/25 11:45:08 WARN (CommonsLogger.java:56) warn Could not find property [null]
> {quote}
> The problem is that the message always say "Count not find property [null]" and it's very hard for the developer to know where the bug is in a long JSP.
> {code:title=com.opensymphony.xwork2.ognl.OgnlValueStack}
> private Object handleOgnlException(String expr, boolean throwExceptionOnFailure, OgnlException e) {
> Object ret = findInContext(expr);
> if (ret == null) {
> if (shouldLogMissingPropertyWarning(e)) {
> LOG.warn("Could not find property [" + ((NoSuchPropertyException) e).getName() + "]");
> }
> if (throwExceptionOnFailure) {
> throw new XWorkException(e);
> }
> }
> return ret;
> }
> {code}
> {quote}
> ((NoSuchPropertyException) e).getName()
> {quote}
> always returns null, instead we should use expr parameter which give the right information.
