Hello Markus,
you can have "unique" sessions only with url-encoded-session-handling. If you
use cookies, then the browser will use the same session-cookie for each tab.
I guess the exception occured if facelets adds automatically new childrens for
some ui-components. This happend asyn in many tabs but will change the same
objects on the server ... but only a idea ... i'm sure other people can tell
more about this :)
Regards
Andreas

Betreff: [Trinidad] ConcurrentModification
Hi List,
I have a page that shows a <tr:table>.
This table refreshs with a <tr:poll>
<tr:poll id="tablePoll" interval="5000" />
<tr:table rows="20" value="#{tableController.scores}" var="data"
id="scoreTable" partialTriggers="tablePoll">
... some columns and stuff
</tr:table>
So far everything works fine, but when I have multiple tabs open in
Firefox showing the same page, I get the exception attached below.
This is not critical because it's not a use case for our application,
but I'm trying to understand what happens here.
Also I've noticed that the session is the same across multiple tabs. Is
there some way to get a new session for every browser tab or is this browser
specific?
I'm using:
Facelets 1.1.14
MyFaces 1.1.5
Trinidad 1.0.3
JBoss 4.2.2 GS
Hope someone can have a look at this and help me understanding how
everything works.
Thanks
best regards
