Hi, I'm trying to implement a custom QueryCache that, like the example in http://community.jboss.org/wiki/QueryCache, does not invalidate some existing register is updated in a specific table. However, unlike the example, I'd like to do that by analyzing which columns were changed in an update. More precisely, I have an User table, which has a lastLogin column. I'd like to keep the QueryCache valid when I update the lastLogin of an User. I haven't found any way to do that yet. Is that possible? Thanks in advance. -- Luiz F. O.
