24 duplicates so far ...

Build: NetBeans IDE Dev (Build 200807040101)
VM: Java HotSpot(TM) 64-Bit Server VM, 10.0-b19, Java(TM) SE Runtime Environment, 1.6.0_04-b12
OS: Linux, 2.6.24-19-generic, amd64
User comments: context switched to the NB window -- was editing ruby with the VI plugin
This is a very severe bug, since all the text has been lost.

I could recover it with the "Undo", though.

I think I was reformatting text while it happened.

Ernie, this seems to be in jVi plugin. Is this something that you have been already tracking? Or do you want me to file
it in jVi's bugtracking system? Thanks

(I've been traveling for a few months, mostly out of touch..., not home until a few weeks)

This sounds familiar, think I fixed it before I left, but haven't released it yet. I didn't realize it was being so
widely reported.

The problem has to do with my original workaround for Issue 114642 . I was automatically subtracting 1 from end offset,
but with 6.5 I was getting updates of (0,0) so when I subtracted one from end this error was provoked. The fix simply
avoids the subtract in problem situations.

Don't know how administrative 3rd party stuff works best. You can [jvi] it and assign to me if that works. Won't release
fix till get home.

Wow, lucky you :-)!

Oh, I see, I should finally fix that.

I don't know either, so I'll just leave this here and assign it to you. It's not critical, 6.5 is almost out of the door
and this is definitely not a showstopper for us. So, feel free to fix it when you have time.

Thanks for a quick reply!!

Just lucky. Been camping. Checked into a resort last night. Try to at least read primary inbox when I get a chance.

> 6.5 is almost out of the door

(I should find the issue's, but...) Did the KeyBindings stuff get changed around? You were talking about a
flag/attribute for a binding called "private" or something-or-another, for those that shouldn't be changeable.

Since there's been very few jVi bugs reported over the last few months, it looks like the jVi integration must be in
pretty good shape (except for this issue).

No, sorry, I didn't managed to do this. I was pinned down by other high priority bugs and this has been working
reasonably well, so I didn't get back to it.


> .. it looks like the jVi integration must be in pretty good shape

I think it is, there are people here in the office who use jVi plugin and I haven't heard any complaints from them. I'm
sure they would come if something was broken. :-)
