Description

[penagate]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2

If design mode is activated form submission triggers the following sequence:

- New window opens showing the message:
> File not found
> --
> Firefox can't find the file at /res/[xpconnect wrapped nsIURI].

- Original window goes to blank page under design mode.

If the form's action attribute is BLANK the new window will show a blank error message.

Reproducible: Always

Steps to Reproduce:
1. Activate Design Mode
2. Submit a form

Actual Results:  
New window opens at the URL:

resource://gre/res/%5Bxpconnect%20wrapped%20nsIURI%5D

showing above error message.

Expected Results:  
Form submitted, target page opened under design mode

Confirmed on the following builds

Was confirned on

We believe it has something to do with the way submissions to own windows are handled in relation to designMode being active.

Change in location of the submit has same effect.

I just noticed the testcase attachment does not demonstrate the effect but the testcase at the URL does.
