> Key: WICKET-1701
> URL: https://issues.apache.org/jira/browse/WICKET-1701
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Environment: winxp sp2 - netbeans 6.1 - tomcat 6.0.16 - java 1.6
> Reporter: dave rafkind
> Assignee: Janne Hietamäki
> Fix For: 1.3.4, 1.4-M3
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> I have approximately this code:
> AjaxLink openCloseLink = new AjaxLink("openCloseLink");
> openCloseLink.add(new Image("icon", new
> CompressedResourceReference(MyComponent.class, "icon.gif")));
> The openCloseLink gets serialized during normal wicket operations,
> which causes a serialization error, see stacktrace below.
> My guess: the "cache" field needs to be marked "transient" in
> org.apache.wicket.markup.html.CompressedPackageResource$CompressingResourceStream
> ----
> ---- STACKTRACE BELOW!
> ----
