Re: [Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)
got it I definately was trying to extend there scope for something they can't
be used for :),
my goal is to get the users to only render what they have to in the vector.
I do not want them to have to re-render the entire Vector each time. The
vector will be constantly added too, there are no modifications to existing
data however. having the user re-render the entire vector becomes
impractical.
I have done some reading on nabble and I require the page to display the
current items without having to re-render them, and rendering new Vector
items as they become available. From what I can see, the solution to this
lies in javascript DOMs... *sigh*... im allergic to javascript :)
Thanks for your assistance again igor.

Re: [Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)
the view doesnt keep the iterator, it just iterates over it once when it
renders. iterators arent meant to be kept, they are throwaway objects.

Re: [Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)
It IS very possible I am going about this from the completely wrong angle...
The gist of it is, that a whole bunch of users will be reading all the
entries from the same vector in an asynchronised manner. So what I thought
that each user would require their own Iterator to keep track of their
progress through the Vector ...
The only actions I performed on the vector is adding to it. I am thinking,
once the iterator is retrieved from getItemModels() does RefreshingView
store the iterator within itself for the duration that its being displayed?
cause if that is the case, i am thinking i dont even NEED to be storing the
iterator with each user!

obviously whatever this thing is, another thread is modifying it, or you
are doing something elsewhere to modify it.
what you should do is instead of returning an iterator directly first copy
the values into an array list and return an iterator to that. java 101.

[Wicket-user] java.util.ConcurrentModificationException with RefreshingView (AGAIN!?!?!!)
Yep, I made some adjustments to code, to allow for any number of users to
join a chatSession, rather then just 2.
What I am doing is , the vector that I am using is within a particular class
and the Iterators for that vector are actually stored within another
subclass which is stored within a hashmap within this class.
I got this working before with Iterators directly declared within the class,
but now that I have moved the iterators to a hashMap so I can store multiple
iterators to the same Vector, it has gone nuts... with the same error:(
Anyway, let me know what you think

You should do that in the Application.init()

Re: [Wicket-user] java.util.ConcurrentModificationException
I think the code is sort of still the same (you use a pretty old version) final Iterator iterator = application.getResourceSettings() .getStringResourceLoaders().iterator(); that is the iterator that goes wrong. But that is strange, are you adding string resourceloaders at some place while the application is running? johan On 2/20/07, Konstantin <[EMAIL PROTECTED]> wrote: What could be the reason of this ?
