Subject [jira] Created: (TAPESTRY-2085) Empty textfield submits null value
Date Thu, 24 Jan 2008 21:38:35 GMT
Empty textfield submits null value
----------------------------------

                 Key: TAPESTRY-2085
                 URL: https://issues.apache.org/jira/browse/TAPESTRY-2085
             Project: Tapestry
          Issue Type: Bug
    Affects Versions: 5.0.10
            Reporter: Kevin Menard
            Priority: Critical


This was initially reported on the dev list by Geoff Callender.

When submitting a form containing a textfield and nothing has been typed into that textfield,
the value will be submitted as null rather than the empty string.  In past version, the empty
string would be submitted.

The net result is NPEs and coercion issues.  If the textfield is bound to a String and that
String is used without checking for null, an NPE will result when none used to.  If the textfield
is bound to any other type, such as an Integer, the Tapestry type coercer will fail with an
appropriate exception (e.g., NumberFormatException).
