-------------------------------------------
Resolution: Duplicate
> No DataSqueezer for JDK1.5 enums - unsqueezing fails
> ----------------------------------------------------
>
> Key: TAPESTRY-576
> URL: http://issues.apache.org/jira/browse/TAPESTRY-576
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Reporter: Vjeran Marcinko
> Priority: Critical
>
> Currently, DirectLink, or some other component that use DataSqueezers
> cannot work with JDK1.5 enums, since it fails during unsqueezing such value.
> Implementing such DataSqueezer should be quite straighforward since all
> JDK1.5 enums have "name" property:
> String name();
> and
> valueOf(String name);
> methods for "squeezing" and "unsqueezing" such enum value. Currently
> it gets squeezed in serialized form, and cannot get unsqueezed.
> Here si the exception that occurrs :
> Unable to decode stream: java.lang.NullPointerException
> java.lang.NullPointerException
> Stack Trace:
