[support] [Fwd: Re: How to add "selected" attribute to select list <option>tag]

Wed Nov 28 17:01:51 UTC 2007

I have noticed with the default values that you need to leave the form
page and return to get it to load the new default values. A refresh of
the screen won't work. I believe it is how the Forms API functions, only
looking for the default values for the initial form display, and any
reload after that it is looking for values from a previous POST.

Hi Steve,

I just tested the code in firefox and it works. Maybe it is a browser
compliancy issue? 

Two of the names are displayed as selected initially.
