JhotDraw does not show created GIF's after update

After upgrading from 1.1.4 to 2.1.4 the GIF pictures created by JHotDraw don't show up.

Instead I get something like:

Error: (3) can't find BlaBla.gif?t=1216292337 in Project

If I look in pub/Project/BlaBla/ I can see BlaBla.gif is there and is accessable by the webserver.

I don't really understand what's going on here. It took a while to actually be able to test JHotDraw on 2.1.4 - most browsers don't support java any more. But on an old XP system I found, it seems to work.

What reports the error? the JHotDraw applet? something else?

Are you unable to create new images, or is it older existing files.

How did you upgrade to 2.1.4? Did you use the bulk_copy tool, or CharsetConverterContrib.

When you look at the pub/Project/BlaBla/ directory, do you also see BlaBla.draw and BlaBla.map? Ah... I just noticed you are using underscores in the name BlaBla.gif. That's legal, but foswiki has always treated files with a leading underscore as a special hidden file. I'm not sure if bulkk_copy would have included hidden files.

Can you confirm if files without the underscore are working?

I had the problem because of ImagePlugin was enabled which did the mess in combination with JHotDrawPlugin. Try to disable it maybe this will help you.
