[infinispan-issues] [JBoss JIRA] Commented: (ISPN-703) Add cache value to event objects

[Paul Ferraro (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557169#action_12557169 ] 

Paul Ferraro commented on ISPN-703:
-----------------------------------

Fetching the value from the data container won't work if the activation is the result of a get(..) that took place within a transaction.  Without a trivial workaround, I'm going to bump up the priority of this jira.

> While implementing a @CacheEntryActivated event handler I encountered an issue where fetching the newly activated value from the cache triggers another activated event, which manifests itself as an infinite loop.
> The workaround for this was to retrieve a cache value directly from the DataContainer, rather than via the Cache API.  This strikes me as a bit awkward and a potential gotcha for new users.
> It would be great if the cache value where available in the event itself, e.g. getValue().  This way users wouldn't have the same temptation to try to fetch the value from the cache, and potentially triggering undesired events.
