Subject [jira] Commented: (WW-3311) NullPointerException in CheckboxInterceptor when parameters are null
Date Sun, 01 Nov 2009 00:44:50 GMT


Cimballi commented on WW-3311:

What's strange is that I identified the problem only when I start using the CheckboxInterceptor,
which is a Struts2 initerceptor. If you look at the ParametersInterceptor and the ParameterRemoverInterceptor,
which are XWork2 interceptors, they both check for null for the parameters. I think both frameworks
should behave the same. Well, that's my point of view as a user, I let the developers choose...

> There is a NullPointerException in the CheckboxInterceptor when parameters are null at
the following line :
> Set<Map.Entry> entries = parameters.entrySet();
> I don't know if "theorically" it should check or not for null parameters, but the XWork
interceptors check it, so I think Struts2 interceptors should also check for null parameters.
