The fix is to replace the parameter declarations in NavBar.java with these:
@Parameter
private String tab = "";
@Parameter
private String subTab = "";
and in Layout.java with these:
@Parameter
private String tab = "";
@Parameter
private String subTab = "";
@Parameter
private String title = "";
I'll release 5.4.15 with the fix shortly.
BTW, I've learnt something. By my reading of the Parameter javadoc
(http://tapestry.apache.org/tapestry5.2-dev/apidocs/org/apache/tapestry5/annotations/Parameter.html),
I thought these 3 declarations should be equivalent:
@Parameter
private String tab;
@Parameter(value = "")
private String tab;
@Parameter
private String tab = "";
but they are not: if the parameter is not bound, then in the first two its
value will be null, and in the third one it will be "".
I've raised https://issues.apache.org/jira/browse/TAP5-1668 .
I'll have a look at your debugging questions soon.
