> DspaceFeedGenerator not serializable?!
> --------------------------------------
>
> Key: DS-296
> URL: http://jira.dspace.org/jira/browse/DS-296
> Project: DSpace 1.x
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 1.5.2
> Reporter: Flávio Botelho
> Priority: Minor
>
> For some reason, the code wants to serialize
> org.dspace.app.xmlui.cocoon.DSpaceFeedGenerator, should it?
> If so than it needs to implement serializable.
> Else somewhere there is a pointer to such an object that shouldn't be.
