Hi Kyler,
The error is shown in the screenshot below. The date range is expecting a string instead of an integer, but it only works with an integer in milliseconds. Using a Date or a string of the date (i.e. toString(Date)) doesn't work. Using a string of the milliseconds doesn't work either.
There's a couple forum posts about this.
I don't think this would cause the refresh issue, but maybe I'm wrong?
I do see the same results in runtime, but it's not as obvious what's causing the issue because you can't see the properties update in real time.
Same as runtime, Read/Write mode in the Designer doesn't work either.
