We have a force.com Sites application for our customer portal, on one particular Visualforce page we have a set of dependent picklists displayed using apex:inputfield.
In Chrome and Firefox this works fine, however, when using IE9 the dependent picklist doesn't populate with any values, no matter what is selected in the parent picklist.
Anyone come across this before/have a workaround. Unfortunately, stopping using IE9 is not an option...
