I have a similar scenario with two dropdowns. This solution mostly worked for me. The only issue is that when I first navigate to the page, the second dropdown is empty until the user either: A) Refreshes the page, or B) Changes the first dropdown's selection.
For clarity, this only seems to happen the first time I navigate to my dashboard either from the dashboard selection or after saving edits to the simpleXML.
I believe the issue is that the second dropdown is being populated and then the first dropdown is calling the tag and leaving the second dropdown unpopulated until the user changes the first dropdown again. It's worth noting that I've tried setting selectFirstChoice to true for both, and true for just the second dropdown.
Has anyone else experienced something similar that would be able to offer up a solution/advice?
