widget disappears after clicking save changes

[robfelty]

Using wordpress 2.7, revision 10186, there is a possible bug in the widget handling. I noticed this for all 4 of the plugins I have written. They worked fine in WP 2.6, but in WP 2.7, when adding a widget, it would disappear from the widget list after saving changes. Eventually I found the problem to be that the id_base cannot be mixed case. At least, changing from mixed case to all lowercase solved the problem for my plugins. But I don't see why that the id_base should have to be all lower case. It seems like WP allows mixed case in most other situations. I have more details about the problem and my experiences on my blog:

I had users of my plugins report this issue in all major browsers. I suspect that the issue is somewhere in the wp_register_sidebar_widget function or the wp_register_widget_control function.

Thanks for all your great work on wordpress!

I can confirm this, not only does it happen on clicking save, but it also happens if you just happen to click on a widget in the center. luckily, if you don't hit have changes and refresh the screen, it will usually still be there.

Can you confirm that this is still occurring?

This should be fixed since the save procedure has changed in 2.8.

Please re-open with feedback if it is still occurring.
