Subject [jira] Created: (TAP5-922) Allow null in LinkImpl.addParameter
Date Tue, 10 Nov 2009 00:31:32 GMT
Allow null in LinkImpl.addParameter
-----------------------------------

                 Key: TAP5-922
                 URL: https://issues.apache.org/jira/browse/TAP5-922
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.1.0.5
            Reporter: Angelo Chen
            Priority: Minor


I have a query string that I need to append to a  Link object, the query string is:

?gender=M&country=

 Link lnk = renderLinkSource.createPageRenderLink("SamplePage");

 lnk.addParameter("gender", "M");		// this works
 
lnk.addParameter("country", null);		

above line failed with :

 RequestExceptionHandler Unexpected runtime exception: Parameter value was null or contained
only whitespace.

A null parameter should be valid in a URL, sometimes it is needed to have Google Analytics
pick up the complete URL even it is null.
