298559 - JavaScript split function does not work in XPI install.js

Status: RESOLVED INVALID

(Core Graveyard :: Installer: XPInstall Engine, defect)

Description

[Dennis Verspuij]

The split method of strings in an XPInstall installer script (install.js) does 
not seem to work, while it surely does exist because Install.alert((new String
("test")).split show "function".

Reproducible: Always

Steps to Reproduce:
1. var sStr="test1,test2"; Install.alert(sStr.split(",").length);
2. Install.alert((new String("test1,test2")).split(",").length);
3. Install.alert((new String("test1,test2")).split(new RegExp(",","")).length);
Actual Results:  
1. error: sStr.split is not a function
2. error: undefined is not a constructor
3. error: undefined is not a constructor

Expected Results:  
1. alertbox with "2"
2. alertbox with "2"
3. alertbox with "2"

I start the installer using the InstallTrigger.install method in an custom XUL 
application run with Firefox 1.0.4
