wat.

Make this work again, it used to work.

Ok, i was hoping that restarting my computer would solve this. But as it 
stands, I can't even share newly created files and any other file in my 
workspace, which means that I can't continue to work on the concurrency issues. 
Can someone please fix this asap? Or at the very least give me some steps that 
guarentee being able to share a file?

I think a possible number of steps to break it was (though it was like 3 am at 
the time)
- before sharing, have a tab open
- edit tab, save
- then try to share, which fails

also, it wasn't that all 3 of my files became unsharable at the same time, it 
seemed like they gradually became unsharable.

was the server running on local host? just trying to reproduce the issue..

It didn't seem to matter. I had one running on a pod, and both my laptop and 
the pod were giving the same errors

Original comment by rharagut...@gmail.com on 19 Apr 2011 at 3:15

GoogleCodeExporter commented 9 years ago 
the error is on line 198 of content manager, the content string is ""

i cant recreated the issue....

i had a server on localhost and shared: (1) file without it being open on 
screen, (2) a file open on screen and (3) a file open on screen after editing 
but before sharing

do note that i only shared with myself because no other clients were connected, 
but that shouldnt be a problem...i also was able to share at least 4 files

everything seems to work fine on revision 454 on Multitype (check 
multitype.editors.EditorManager) and revision 445 of the server (check Server)

This is really bizarre. 
I've stepped through the program, and everything looks fine up until 
openDocument in EditorManager, 
I don't really know what these things do, but here's what's happening:
on line 169, it does not go through the loop, i guess length=0,
Scanner is created (successfully it seems)
content intialized to ""
scanner.hasNext returns false as it doesn't go into the while loop
content attempts to substring ""

what are your revisions?

also, this is probably more important, but my editormanager is on revision 457

my server.java is at 445, but markupprocessor.java is at 461

ok, it should be good now.....

i bet you were trying to share empty files......just like you said, that is why 
the array out of bounds was happening: 0 length minus 1 is -1. 

anyway, all should be good now, please update to revision 462 on 
multitype.editors.EditorManager
