in our application, we have many cases where we need to select a specific value in a listbox while the page is loading. for various reasons, we have to do this via javascript, but there is a bug in the form manager in mozilla that breaks everything. basically, although the embedded js code appears to successfully set the selectedIndex for a listbox ( an 'alert' shows the expected index ), when the page is fully loaded, a completely different option is selected. its almost as if the form manager is 'remembering' some values as the page loads, then AFTER the page is all loaded, it runs around and modifies the selected items again, thereby undoing any embedded selectedIndex changes. see the provided URL for a pretty simple and succinct example.

jkeiser, is this really form manager or the stuff you're working on?

Not form manger. Reassigning.

'Tis fixed in bug 34297. Setting dependent. (This may be a dup, but it relates to setting selectedIndex instead of getting it, and I couldn't find such a bug in my cursory search.)
