Menu
I asked about this on the jquery forum a few weeks ago without luck, so I will try again here :)
I've made a simple widget for a project I'm working on, but I have encountered an odd problem.
It is easiest to explain it with an example implementation. http://decko.dk/buttontest
On the page there are 3 button. The first one is my drop down widget. The next one is a regular disabled button (A) and the last one a regular enabled button (B). If you then refresh the page (press F5 or whatever) the enabled button is mysteriously now disabled. I have no clue why this happens, but if button A is not disabled to begin with, button B will not be disabled when refreshing. Also, if I remove the call to insertAfter in my widget-code, the button will not be disabled. Can anyone shed light on why this strange behavior occurs?
By the way, I have only been able to reproduce this in Firefox.

I believe this is a bug in how Firefox remembers form field/control values and states:
<button> elements in the document, and <button id="button_a"> is disabled. (When the jQuery UI styled button is enabled or disabled, it sets the underlying element to the same state.)<button> is disabled.<button>, but since no script has been run, the second button is <button id="button_b">.<button id="button_b">, it sees that it is disabled and continues to style it as disabled.There are two issues here:
The test case can simplify down to just adding a <button> element dynamically and disabling <button id="button_a">, no jQuery / jQuery UI necessary:

a.disabled = true;
};
