Bug 15592 – DOM Exception opening up client-side database example for the first time

• Component: WebKit Website
• Status: RESOLVED FIXED

[David Kilzer (:ddkilzer)]

* SUMMARY
"DOM Exception 12" is reported the very first time the DatabaseExample.html page is opened.

* STEPS TO REPRODUCE
1. Remove ~/Libraries/WebKit/Databases if it exists.
2. Launch Safari + WebKit.
3. Open URL:  http://webkit.org/misc/DatabaseExample.html
4. Open JavaScript Console.

* EXPECTED RESULTS
No "DOM Exception 12" should be reported in the JavaScript Console.

* ACTUAL RESULTS
A "DOM Exception 12" is reported in the JavaScript Console:

SYNTAX_ERR: DOM Exception 12
http://webkit.org/misc/DatabaseExample.html
Line: 264

* REGRESSION
Not applicable as client-side database support is a new feature.

* NOTES
Tested with a local debug build of WebKit r26847 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).

Also, I believe this "DOM Exception 12" prevents a new blank note from being created the first time the page is loaded.

The problem is that there is a race condition between creating the WebKitStickyNotes table for the first time and querying the table in the loaded() function.  The loaded() function may get called before the WebKitStickyNotes table is created.

Oops, I fixed this for the original example. But it wasn't fixed in Adam's version.
