> Eliminate random crash of theme engine
> --------------------------------------
>
> Key: NXP-3484
> URL: http://jira.nuxeo.org/browse/NXP-3484
> Project: Nuxeo Enterprise Platform
> Issue Type: Bug
> Affects Versions: 5.2 RC
> Environment: JBoss 4.2.3 GA, java 5, nuxeo-features revision 2817
> Reporter: Radu Darlea
> Assignee: Jean-Marc Orliaguet
> Priority: Major
>
> The WebEngine sites module now uses heavily fragment with models attached.
> The fragments are initialized through specific ActionFragments. After this
> implementation is in place, the applications starts to crash randomly when in
> sites view. There is no certain sequence of steps to reproduce, and once
> happening it doesn't happen again doing a refresh for instance. Doing the
> same thing again it doesn't yield the exception. And it appears after various
> actions (couldn't say it is a single widget affected).
