As the title says, for some reason, when I bind a dropdown `value` prop to the appropriate input parameters on a view, it isn't displaying registering those changes on my view. I feel as if I've done this before, but I can't figure it out this time. Based on the [docs](https://docs.inductiveautomation.com/display/DOC81/Pages+in+Perspective), it should work how I have it set up - it describes the exact scenario I'm doing.

Page parameters:

View parameters:

It shows in the designer when I refresh the binding:

Do I need to refresh the bindings on the dropdowns on view startup? I know `lineId` and `stationId` are coming through because if I add them to a label on the view, they'll show up as they should.

I bounced ideas off of my friend and he mentioned that the page parameters are strings while the `value` properties in the dropdowns are integers. I used the expression `toInt({view.params.stationId})` to convert it to an integer and it worked.
