> Key: TAPESTRY-271

> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 3.0.2
> Environment: All
> Reporter: Hanson Char
> Assignee: Brian K. Wallace
> Fix For: 3.0.5
>
> There appears to be a concurrency bug in DateValidator:
> The "_calendar" member field in DateValidator is apparently not
> thread-safe. The only place it is used is within the toObject()
> method, which modifies the time of _calendar. To resolve this issue,
> this member variable should be changed to be a local variable, and
> simply replace the code in toObject()
> from
> if (_calendar == null)
> _calendar = new GregorianCalendar();
> to
> Calendar calendar = new GregorianCalendar();
