---------------------------------------
try the future 2.4.1.CR2 which is tagged in SVN that you can get by "svn co
http://anonsvn.jboss.org/repos/portal/tags/JBoss_Portal_2_4_1_CR2/". The caching
implementation has been improved and is tested with different use cases.
It also exist in the main trunk (future 2.6 alpha)
Programatic control of portlet caching behavior
-------------------------------------------------
Key: JBPORTAL-1137
URL:
http://jira.jboss.com/jira/browse/JBPORTAL-1137
Project: JBoss Portal
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Portal Portlet
Affects Versions: 2.4 Final
Environment: Portal 2.4, JDK 1.5, WindowsXP
Reporter: Jerry Lacy
Assigned To: Julien Viet
Attempts to programatically alter the EXPIRATION_CACHE setting of a portlet from within
the doView() method has not effect.
e.g.
response.setProperty( RenderResponse.EXPIRATION_CACHE, "0" );
Unless I am missing something, it doesn't appear that this was implemented anywhere
(as of the 2.4 final release). I believe the problem is on line 65 of
org.jboss.portal.portlet.aspects.portlet.ProducerCacheInterceptor.invoke(). The cache
expiration value is being updated on each request using the configured EXPIRATION_CACHE
value regardless of whether an EXPIRATION_CACHE property was set on the response. I added
the following test which seems to work based on what little testing I have done so far:
// Update the fragment cache info only if the value has not been overridden during render
processing
if ( fragmentResult.getProperties().getProperty(RenderResponse.EXPIRATION_CACHE) == null
) {
fragmentResult.setExpirationSecs(cacheInfo.getExpirationSecs());
}
