[JBoss Portal] - Jboss Portal - Partial Refresh

by adriano.ferranti

Does anybody have already used the "partial refresh" in JBoss Portal? I've followed the steps as described in reference guide, but the portal still performing a full refresh instead of just refreshing the changed portlet. Perhaps I'm missing some step. If someone has some link for an example application using this feature or something like that, it would be nice !

No, this is not true. anonymous wrote : what's the difference between a new conversation starting from the same bean instance or from different bean instance? why the behavior is different? There is no difference, if there is, it is a bug.

"gus888" wrote : No, you didn't do anything wrong. As I posted above, the @Begin in booking example always was invoked in the same bean ("hotelBooking"), so no exception thrown. What Seam component conversation demarcation is expressed in has no effect on conversation boundaries or behaviour.

[JBoss Seam] - Re: Action execution upon page load

by pete.muir＠jboss.org

Yes, it is something we have discussed (and consider useful), but it is currently hard to implement (I think we would need an extension point added to facelets OR to use gravel style inline to the page declarations of stuff like page actions). So, do open a JIRA issue.

[JBossCache] - JDBCCacheLoader bad performance when writing to DB

by gmeroz

I use JDBCCacheLoader (JBossCache 2.0.0GA & Oracle in JBossAS) to persist a cahe to DB. When the cache is big it takes hours to persist. It takes a lot of time to write the item into the DB. i loaded YourKit profiler to analyze the problem and learned that most time is spent in running SQL commands. YouKit shows that the time is spent mostly on Oracle driver's executeQuery & pingDatabase commands and that the following SQL commands are run: 1. 2600 * insert into jbosscache_table (obvious) 2. 15000 * select node from jbosscache_table where fqn=? 3. 600 * update jbosscache_table set node=? where fqn=? i don't understand why there are 6 times more "select" statements than "insert". Is it related to the number of '/' in the item key?

[JBoss Seam] - Re: How to control end of conversations/state of stateful be

by pete.muir＠jboss.org

"trouby" wrote : I still don't get it, what about links that -should- start a new conversation? is it possible to combine begin/end annotations together for the same method? like ending the current conversation and starting a new one? Yes, but you have to end the current conversation before a redirect, and start a new conversation after a redirect (you can do this from pages.xml or from annotations). I've not seen a great use case for this though. anonymous wrote : btw, I have a seam link which invoke an method that is annotated with @Begin, invoking the same link just after the first invocation throws "begin method invoked from a long-running conversation, try using @Begin(join=true)", so what should I do in such situation?? I don't want -another- conversation to start in this case, If you want to join the current conversation, use join=true, otherwise, design your app so the use can't be on that page when a long running conversation is in progress. anonymous wrote : I guess I'm doing something wrong, as in seam booking example the 'setHotel' is annotated with @Begin and can be invoked many times without this exception, Yes, because you can't be on the page which calls this method and inside a long running conversation.

Thanks Pete, Could that become a new feature request? I believe it can be useful when rendering UI components.

[JBoss Seam] - Re: error in creating JBPM process with seam-generated Home

by pete.muir＠jboss.org

I guess the error occurs when creating the process, not when processing the method (the process is created after the method completes successfully). But it is very hard to understand from that stack trace what the problem is. Post the process, lets see if we can eyeball a problem with it./ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116363#4116363 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4116363
