Combobox with computed values getting reset with page update

Is anyone experiencing a problem with Firefox (no problem in IE) and 8.5.1 Xpages resetting combobox values (and selected value) when updating the page?

I have a combobox on an xpage with computed values, onchange triggers an update that is wiping out the selected value in the combobox. Using static values for the choices in the combobox works fine.

I’ve already tried changing the $ to # in the source for <value… tag to no avail.

Stranger still, if you select the last value in the list of choices, the selected value doesn’t get wiped out.

Anyone else seen this? Anyone have any ideas?

thanks
