["Jochen Kemnade (JIRA)" <ji...@apache.org>]

Jochen Kemnade updated TAP5-736:
--------------------------------

    Labels: bulk-close-candidate  (was: )

This issue has been last updated about 1.5 years ago, has no assignee, affects an old version of Tapestry that is not actively developed anymore, and is therefore prone to be bulk-closed in the near future.

If the issue still persists with the most recent development preview of Tapestry (5.4-beta-6, which is available from Maven Central), please update it as soon as possible. In the case of a feature request, please discuss it with the Tapestry developer community on the dev@tapestry.apache.org mailing list first.

> Component TextField has parameter "validate" annotated by
>    @Parameter(defaultPrefix = BindingConstants.VALIDATE)
> There is no attribute allowNull, but it has default value "true" (http://tapestry.apache.org/tapestry5.1/apidocs/org/apache/tapestry5/annotations/Parameter.html#allowNull()). 
> So null value is allowed according to specification.
> But if you set parameter validate to null, NullPointerException is thrown from AbstractTextProperties.begin(MarkupWriter writer), line: 173.
