SortableAjaxBehavior with multiple operations in the same time does not work properly

[GoogleCodeExporter]

What steps will reproduce the problem?

1. create two connected lists with SortableAjaxBehavior following UPDATE 
notifications only, by using 2 ListView components
2. start dragging 5 elements from the first list to the second list and watch 
the logs for the ajax UPDATE notifications (2 per each moved element and I use 
them to add/remove from the ListView model)

What is the expected output? What do you see instead?

- I expect that all the elements dragged make it successfully to the second list
- Instead, if I remove the element from the first ListView model when receiving 
the notification, the indexes for the other 4 elements remaining to be dragged 
are messed up and either wrong elements are moved or there is an 
IndexOutOfBounds exception if I am playing with the last elements.

Please note that this works fine if I move them one by one, but I need to 
support moving more of them and not blocking the UI for this.

Similar problem with the index occurs when I add (not just remove) 5 new 
elements to the other list in the same time.

Please let me know if there is a nice solution for this other then keeping 
track of dirty information and updating the model lists later.

What version of the product are you using? On what operating system?
<dependency>
        <groupId>org.odlabs.wiquery</groupId>
        <artifactId>wiquery</artifactId>
        <version>1.2.1</version>
</dependency>
OS: Windows 7, Gentoo Linux

Please provide any additional information below.

If I am not using the behavior as I should, please point me to the right 
direction to avoid the above problem.
Thanks!

Hi,

Can you submit a sample of your project please to detect where the problem can 
be please ? (an eclipse project, a maven project ...)

Yes, I will do that. Apologies for the too complex explanations.

Attached is a sample project with this. Just try to move ALL the elements from 
the first list to the second one and you will see the exception. You will 
notice that the indexes are messed up after removing the first element. Similar 
problem occurs for add or when manipulating the model list while using this 
behavior.

Thanks!
