Howard M. Lewis Ship closed TAP5-1401.
--------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
Its unfortunate that sometimes components must implement public methods that
are not intended to be invoked except under certain situations (perhaps we need
to make that a @Property, or create a new annotation to identify "hands off"
methods). In any case, see the workaround in the comments.
> 5.2.4 Form's getDefaultTracker() incompatible with 5.1.0.5
> ----------------------------------------------------------
>
> Key: TAP5-1401
> URL: https://issues.apache.org/jira/browse/TAP5-1401
> Project: Tapestry 5
> Issue Type: Bug
> Components: documentation, tapestry-core
> Affects Versions: 5.2.4
> Reporter: Michael Gentry
> Assignee: Howard M. Lewis Ship
> Priority: Minor
>
> In Tapestry 5.1.0.5, you can have code such as:
> @Component
> private Form inputs;
> ...
> if (inputs.getDefaultTracker().getHasErrors())
> ...
> This fails in 5.2.4 because getDefaultTracker() returns null if there are no
> errors. This appears to be related to this closed bug:
> https://issues.apache.org/jira/browse/TAP5-979
> Perhaps getDefaultTracker() should check for a null and return an empty one
> to be backwards compatible with 5.1.0.5? Alternatively, document it as a
> known incompatibility in the release notes.
