chartjs : Microflow should have one parameter of type ....

1
Hi, I want to test the radar plot widget  and tried to use the chartjs widget. I followed the instructions but at the end I get the message “Microflow should have one parameter of type MyModule.ChartWrapper.” I added the parameter for the wrapper at the related microflow. But that message does not disappear.   Is there a known issue of modeler 7.23.2 and chart.js? If yes, is there another radar plot widget? Thanks a lot!

Is your widget inside a dataview that can provide the input parameter the microflow needs?

Yes, of course. It’s embedded into a dataview n the same way as in the example of the mendix howto.

But it does still not work… ? More than one input parameter is required?
