Howard M. Lewis Ship updated TAP5-1668:
---------------------------------------
Summary: JavaDoc for @Parameter.value() should be clearer about the empty
string (was: Unexpected behaviour setting default of String parameter to "" )
> JavaDoc for @Parameter.value() should be clearer about the empty string
> -----------------------------------------------------------------------
>
> Key: TAP5-1668
> URL: https://issues.apache.org/jira/browse/TAP5-1668
> Project: Tapestry 5
> Issue Type: Bug
> Affects Versions: 5.2
> Reporter: Geoff Callender
> Priority: Minor
>
> After reading the Parameter javadoc I expected these 3 to 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 "".
> The javadoc is
> http://tapestry.apache.org/tapestry5.2-dev/apidocs/org/apache/tapestry5/annotations/Parameter.html
> .
> Is the behaviour wrong or does the javadoc need to be clearer?
