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
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.
