Vicente J. Ruiz Jurado commented on WAVE-312:
---------------------------------------------
This annoying bug is still present.
I can reproduce easily using the file store, but I can't with the memory store.
For some reason the delta retrieved in
DeltaStoreBasedWaveletState.readDeltasInRange
delta = reader.getDelta(i);
is null.

> Not saving editions when concurrent editions in same wave
> ---------------------------------------------------------
>
> Key: WAVE-312
> URL: https://issues.apache.org/jira/browse/WAVE-312
> Project: Wave
> Issue Type: Bug
> Components: Web Client
> Environment: Tried in http://waveinabox.net and http://kune.cc
> Reporter: Samer
> Labels: bug, concurrency, edit,, editor,, persistence
>
> - Alice: begins editing a blip of a wave. She needs to write a long paragraph.
> - Bob: begins editing a while after Alice, in another blip in the same wave.
> - Alice doesn't see that Bob is writing, nothing new appears
> - Alice finishes editing her wave and moves to another wave.
> - Bobs finishes editing that wave and moves to another wave.
> - When Alice comes back to the same wave, she sees her edition was not fully
> saved. It saved only until the instant that Bob began editing.
> - When Bob comes back to the wave, he sees nothing of what he wrote was saved.
> Sometimes it shows the mysterious delta error from:
> http://www.mail-archive.com/[email protected]/msg02036.html
> https://issues.apache.org/jira/browse/WAVE-307
> but other times it shows nothing on the log, so don't know if it's directly
> related or just chance.
