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.

> In my case, the value must be an integer to work. My value was a date, so I added a Transform in my binding to convert the date to an integer.

> I’m using strict x-axis date ranges on an XYChart bound to two DateTime Pickers, and after upgrading to 8.0.6 the chart stopped working correctly. In order to get the chart working again, I had to add a transform to get the dates into milliseconds. It would be nice if these properties would accept the java.util.date objects that the DateTime Picker produces. XYChart.xAxes.0.date.range.max XYChart.xAxes.0.date.range.min

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.
