Unexpected behaviour setting default of String parameter to ""
---------------------------------------------------------------
Key: TAP5-1668
URL: https://issues.apache.org/jira/browse/TAP5-1668
Project: Tapestry 5
Issue Type: Bug
Affects Versions: 5.2.6
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?
