Orbeon losing/deleting characters when typing fast

Does Orbeon have any known issues around occasionally 'losing' input when typing fast into inputs/textareas with incremental="true"?

We have reports from testers & users of the application 'correcting' their input and removing the last few letters they've typed. That is, they see the letter appear when typed, then the server seems to delete it.

I have trouble replicating it - I *think* I've seen it once, but I can't get a video of it. It may be related to server latency/speed.

This is using 3.7.0beta1+.200904290452.

Adrian,

This got broken at some point but then fixed since then AFAIK. Issue
was that value coming back from the server through Ajax would
overwrite the value you were typing.

Great, thanks Erik.

Would you have an idea what the changeset might be? We might have to backport the fix into our current version rather than risking an upgrade.

Do a search for doUpdate in the latest xforms.js to see the logic we now use to determine if we should or shouldn't update a field based on a value that comes back from the server. (But there might be more than just that part of the code you need to update.)
