(SeaMonkey :: Help Documentation, defect)

Description

[Brant Gurganus]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.9+)
Gecko/20020419
BuildID:    2002041903

When I first open a help window by clicking a help button in preferences, I get
a JavaScript Exception.

Reproducible: Always
Steps to Reproduce:
1. Open preferences.
2. Navigate to Application.
3. Click Help.

Actual Results:  Mozilla Help opens, but JavaScript console shows error.

Expected Results:  JavaScript error does not occur.

In the JavaScript console, the following appears when the button is pressed:
Error: [Exception... "'JavaScript component does not have a method named:
"onStatusChange"' when calling method: [nsIWebProgressListener::onStatusChange]"
 nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location:
"<unknown>"  data: no]

When Mozilla Help is already open and a Help button is pressed, this exception
does not occur.

All of these are examples of help buttons for which no help has yet been
created. Most of these are mozilla-only UI, too, like the DOM Inspector pref
panel and so on. ACCEPTING. We can at least put pointers to some basic help
content for these in the UI (e.g, in pref-help.js, where the context keys for
the pref panel are listed), even if there is as yet no specific contextual help.

I no longer receive that exception, even in strict mode when I click help for
something that has no help.
