Subject [jira] Resolved: (JXPATH-146) JavaBean XPath with uppercase initial characters
Date Fri, 26 Mar 2010 14:42:27 GMT


Matt Benson resolved JXPATH-146.

    Resolution: Not A Problem

To be honest I can't see how this feature fits into JXPath's mission to provide xpath handling
of Java object graphs.  I could argue it would be just as easy for you to write a convenience
layer over JXPath that does what you want, or simply clone BeanPointer, BeanPropertyPointer,
and BeanPointerFactory and register your factory with a higher priority than BEAN_POINTER_FACTORY_ORDER
to intercept the normal creation of BeanPropertyPointers with your own pointer implementation
that includes the behavior you desire.

>          Issue Type: Improvement
>    Affects Versions: 1.3
>            Reporter: Ram
>            Priority: Minor
> XPath expressions executed against a JavaBean only work when the initial character is
lower case.
>  context.getValue("firstName")   //works
>  context.getValue("FirstName")   //doesn't work
> The code internally is looking at PropertyDescriptors and these start with lower case
as per the JavaBean spec.
> I will be nice if both versions work ( just like 'firstName' and '@firstName' work even
though JavaBeans don't differentiate attributes vs elements).
> The fix may be simple as converting the initial character to lower case before the PropertyDescriptor
lookup. Haven't looked at the impacts in detail though.
> Thoughts ?
