Hi, In my Mx 8.6.4 project I downloaded the charts package from the appstore. I added a bar chart to my page and under the advanced settings enabled the developer mode to get a live editor in the front end (https://docs.mendix.com/appstore/widgets/charts). The live editor shows up but: My cursor position is funky, in the screenshot my cursor is actually at the end of the line but is visually placed before the end Changing settings does not work, i.e. no live update Clicking on the info button gives me an error message: "An error occurred in a "com.mendix.widget.custom.BarChart.BarChart" widget. Check updates for the widget in the Mendix App Store or contact the widget developer.” The same feature works perfectly in the demo project provided by Mendix: https://charts102-sandbox.mxapps.io/#/home Any ideas?
