Subject [jira] Commented: (JXPATH-80) boolean conversion of javabean getter values returning NULL fails
Date Wed, 18 Apr 2007 21:32:15 GMT


Nico Max commented on JXPATH-80:

I've tracked this down and I think I was able to resolve the issue.

First off, my testbean was not public as for one reason for the test to fail ... :-)

There is a method retrieving the length of a collection-like result of a bean getter in BeanPropertyPointer,
but a real check for the NULL-case was missing, so I've patched that.

Unfortunately this does not fix your findings so I guess this issue should stay open.

> According to the JXPath User Guide a Javabean Getter returning NULL, regadless of the
type, will be converted bo Boolean FALSE. But trying to build a boolean expression from this
fails as the attached testcase shows.
> It seems that the type the bean getter returns matters, as a NULL String for example
works as expected.
