[JBoss Seam] - problem with Faces Messages in server interceptor
by milesif
Hi everybody,
I created an interceptor of type InterceptorType.SERVER (I understand it should be the innermost, eg the one that directly calls the methods of my itercepted classes).
The interceptor works fine, but when in its @AroundInvoke method I trap an exception, add a faces message using the following code
FacesMessages facesMessages = (FacesMessages) Component.getInstance(FacesMessages.class);
| facesMessages.addFromResourceBundle(
| FacesMessage.SEVERITY_ERROR, "msgs.db.constraint", "", e.getMessage());
|
and rethrow the exception, most of the time the message does not show up in the error page. It seams that if I set a breakpoint after adding the message, stop the execution for a while and then resume it I can see it. It looks like if I wait long enough I can see it, as if it is set by a concurrent thread.
Is that possible? otherwise what's going on ? Did I do anything illegal, adding faces messages from my interceptor ?
Thanks in advance for help
Ciao Francesco

[JBossCache] - Retrieving state problem
by kkrivopustov
Hello,
we have a cluster with 2 nodes, and have to restart one server while other is working. Sometimes after several restarts of each node in turn the TreeCache doesn't retrieve the state on startup, because it doesn't see other node. After some time it finds the other node, but it doesn't affect its state. This problem is very serious for us, because we store user sessions in the cache, so if the new node doesn't receive the state from existing node, all user requests to the new node fail.
Here is log excerpt from the starting node:
| 2007-03-02 19:45:08,367 DEBUG [org.jboss.cache.TreeCache] Starting jboss.cache:service=GearSessionsTreeCache
| 2007-03-02 19:45:11,878 INFO [org.jboss.cache.TreeCache] viewAccepted(): [192.168.3.71:7810|0] [192.168.3.71:7810]

We use TCP stack of JGroups:

| shun="false"
| print_local_addr="false"
| down_thread="true"
| up_thread="true"/>
| <pbcast.STATE_TRANSFER up_thread="true" down_thread="true" />
|
Any help with this would be very appreciated...

[JBoss Seam] - Pre-filling IceFaces SelectInputText
by damianharvey
I am trying to populate a SelectInputText (auto-complete) field for when a user edits a record. The SelectInputText works fine however I need the current value to be displayed when a user goes in to edit the record.
I have followed the advice from this thread: http://www.icefaces.org/JForum/posts/list/3718.page
But get a NullPointer as my method can't find the JSF component.
My JSF page has a form (<h:form id="scheduleDate">) and in that form is the SelectInputText component (<ice:selectInputText id="unlocode"...)
My code to populate this component is:
| //Set the list of matches to the incoming value
| selectList.add(new SelectItem(scheduleDate.getUnLocode(), scheduleDate.getUnLocode().getName()));
|
| //Find the JSF component from the page
| SelectInputText sit = (SelectInputText)FacesContext.getCurrentInstance().getViewRoot().findComponent("scheduleDate:unlocode");
|
| //Set the selected item on the component (this is where the null pointer occurs
| sit.setSelectedItem(scheduleDate.getUnLocode().getLocode());
| sit.setValue(scheduleDate.getUnLocode());
|
Am I correct in the notation of "scheduleDate:unlocode"?
Has anyone got a working example of this sort of thing?
Thanks,
Damian.
