Bug 11803 – Incorrect use of alternate content inside the <object> element

• Component: Forms
• Status: RESOLVED FIXED

[Vlad Alexander]

Form controls inside the <object> element should not send data to the server if the object is rendered correctly. Content inside the <object> element is alternate content not additonal content to the <object> element. In this example, data from the <textarea> should not be sent to the server if the <object> element is rendered correctly:

<object data="logo.gif" type="image/gif" width="180" height="60">
<textarea id="abc" name="abc" rows="5" cols="70">Hello World!</textarea>
</object>

Test case at:
http://misc.xstandard.com/apple/alternate-content1.asp

We are a browser plug-in vendor and would very much like to use the above construct with our plug-in called XStandard. IE and Opera already support correct use of alternate content in the <object> element.

[Vlad Alexander]

To further clarify the request for this bug fix, when our plug-in is not installed on the client, we need to provide a "textarea" in its place. To do this, we use the fallback mechanism built into the "object" element. For example:

<object type="application/x-xstandard" name="editor1">
<textarea name="editor1"></textarea>
</object>

Both "object" and "textarea" need to have the same value in the "name" attribute because our plug-in is used in existing content management systems (CMS) where it is very difficult or impossible to change the server-side code to received HTTP POST data from 2 form controls instead of one for what is really one control. Since both controls have the same "name", the server will received double the data.

I tested the problem in the latest WebKit and it looks that the bug is already fixed.

Any confirmations?

I'm still seeing this issue with WebKit r34513 (i.e., I'm seeing "abc = Hello World!" in the result). Firefox behaves the same.

Argh... You are right. Description of the bug was unclear for me, so I incorrectly interpret result of the test case :(
