Dan Allen commented on JBSEAM-2320:
-----------------------------------

Within the refresh() method in Query.java I suggestion putting:

if (Events.exists()) { Events.instance().raiseEvent("org.jboss.seam.refreshQuery." + getClass().getName()); }

We can either append the class name or use Seam.searchComponentName(getClass()) to resolve the name from the @Name annotation. There is still some limitation here since the EntityQuery class could be used multiple times via component configuration and there would be no good way to tell them apart.

> It is very useful to know when a query is refreshed, either because a parameter is dirty or because some other part of the application forced it to refresh itself. This message passing is extremely important when working in a caching situation.
> I am thinking something like:
> org.jboss.seam.queryRefreshed
> perhaps we pass the ejbql or the Query component as an parameter to the event
