Cola is operating on single character insertions and deletions as atomic modification units. It does not support the insertion of multiple characters (via the clipboard) at once. The same applies to other multi-character operations such as deletion of text > single character by for instance marking a section of text and hitting "Delete/Backspace". If an editing session participant executes an unsupported modification of this kind on her/his local document, remote sites discard the modification upon receipt - essentially resulting in documents being out-of-sync. Cola should be extended/adapted to allow for insertions and deletions of texts greater than a single character in length.

A proper Real-Time Shared Editor would be of great use to my team. Really hope this one gets fixed soon.
Jeremy, I am working on this right now. I'd love to hear more about your specific use case for shared editing ...
Our main use case for the shared editor is for paired programming. We want to be able to do paired programming but have each developer sit at their own desk and for both users to be able to work on the same file at the same time. If both developers can be typing at the keyboard it can in crease productivity instead of only one of the two developers doing the typing. We also want to use the shared editor when providing support to other teams within our organization and people on our own team. We want someone having problems with a particular bit of code be able to share the editor with someone who's more knowledgeable and to be able to help them through the tough bits. Also for training more junior developers, we can pair a more experienced person with a less experienced one and they can work together via the shared editors. I can't recall, but are you able to share the editor with more than one other person at a time? It'd be useful if you could share with multiple people for doing things like code reviews. What'd be really cool is if you could share an entire project or workspace with other people so that you could do things like Open Declarations and navigate multiple source files to do true paired programming. We've looked at other solutions that do this kind of thing (n-brain) but we really don't want to move away from Eclipse.
Changed to new ecf.cola component.
Committed additions and changes on behalf of Mustafa Isik to address this bug...to HEAD and Release_2_0.
Fixed. A document, such as a source file, can be shared between two participants and edited simultaneously. The cola real-time shared editing mechanism resolves conflicts that arise from messages crossing on the wire, leaving a consistent document state at both sites. Message payloads can be multi-character insertions, deletions and replacements. Is available as of ECF 2.0.0 RC5 - look for DocShare and Cola.

As Mustafa says in previous comment, this change will be in ECF 2.0.0 RC5 (for distribution 6/17/2008), and in all subsequent builds/RCD and releases. Note: Due to bug #237269, ECF RC5 is *not* backward compatible with previous 2.0.0milestones/RCs.
