514411 - Register Prism with built-in js-functions as Mailto-Handler per User

Status: RESOLVED WONTFIX

(Mozilla Labs :: Prism, defect)

Description

[michael.groene]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)
Build Identifier: 1.0b2

I'm trying to register my webmail-app to handle mailto-Links.

The Problem seems to be, that our security policy doesn't allow to write in HKEY_LOCAL_MACHINE (monitored with regmon; result is "ACCESS FORBIDDEN".

So I need to register the Mailto-Handler in the userprofile:
HKEY_CURRENT_USER\Software\Classes\mailto\* instead HKEY_LOCAL_MACHINE\Classes\mailto\*  (also see Additional Information)

When I register Prism in my Userprofile and then clicking a mailto:-Link, the Prism-Application will be started, but something will go wrong and I get an error in the Error-Console of Prism:
Error: [Exception... "Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]"  nsresult: "0x804b000a (NS_ERROR_MALFORMED_URI)"  location: "JS frame :: file:///C:/Dokumente%20und%20Einstellungen/username/Eigene%20Dateien/prism/prism_distr/components/nsPlatformGlue.js :: newURI :: line 140"  data: no]
Source File: file:///C:/Dokumente%20und%20Einstellungen/username/Eigene%20Dateien/prism/prism_distr/components/nsPlatformGlue.js
Line: 140

Prism will be focused, but nothing further happens.

Reproducible: Always

Actual Results:  
Nothing but errors

Expected Results:  
Compose-Form should be loaded

Prism should register itself not globally, but for the loggedin user.

I found out, that when I use my own Registry-File (the one writing in CURRENT_USER) the problem is, that Prism doesn't know about that.
So I need a mailto-uri in the profiles' prefs.js:
user_pref("prism.protocol.mailto", "http://xyz.local/?url=http://xyz.local/imp/compose.php?to=%s");

Is it possible to add this by javascript within the webapp?

You can set the preference using the corresponding XPCOM APIs. See https://developer.mozilla.org/en/Code_snippets/Preferences for more information.

Prism isn't maintained anymore. Mass closing of the bugs.
