456325 - hook to watches fails, but only when watch is set to active xmlHTTPRequest object

Status: RESOLVED DUPLICATE of bug 446120

(Other Applications Graveyard :: Venkman JS Debugger, defect)

Description

[Paul Allsopp]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.16) Gecko/20080702 Firefox/2.0.0.16
Build Identifier: 0.9.87.4

Error message reads:

Internal error processing hook “watches:hook-eval-done”.
TypeError: this.value has no properties @ <chrome://venkman/content/venkman-records.js> 735

When this happens, the watch window becomes unusable in that the expanded watch cannot then be collapse, and additional watches do not appear correctly, similar problem.


Reproducible: Sometimes

Steps to Reproduce:
1. create xmlHTTPRequest
2. add object as watch expression, setting breakpoint on readystatechange
3. send request to server using POST method
4. play through so debugger only stops at breakpoint...4 times
Actual Results:  
After this occurs, the debugger needs to be rebooted to fix the issue, and this in turns leads to the necessity to also reboot the browser.

Expected Results:  
Happiness

Venkman is awesome, it would be nice to get this one squared away.
