[jira] Created: (TAPESTRY-576) No DataSqueezer for JDK1.5 enums - unsqueezing fails
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:

[jira] Commented: (TAPESTRY-576) No DataSqueezer for JDK1.5 enums - unsqueezing fails

Vjeran Marcinko commented on TAPESTRY-576:
------------------------------------------
Although this bug with deserialization of JDK1.5 enum is fixed in beta-5, I still think that it would be useful to have DataSqueezer for enum values, thus not being treated as others unknown instances, because they are currently squeezed as long byte array, such as :
<input type="hidden" name="For" value="OrO0ABX5yAB5oci50aXMuZGV2cmVwby51c2Vycy5Vc2VyJFJvbGUAAAAAAAAAABIAAHhyAA5qYXZhLmxhbmcuRW51bQAAAAAAAAAAEgAAeHB0AARST09U"/>
whereas they have such a nice name() and valueOf(name) pair of methods, like perfect for squeezing/unsqueezing such values.
