I added in my application the screening widget and until then everything was working properly. From today, after I draw a polygon, on an active layer in the layerlist widget, clicking the "Report" button, the area where the occurrences are shown for certain active layers, does not load anything. The strange thing is that no error is displayed on the chrome console. It just does not work anymore. Even though I click the "update" button, nothing happens. If anyone can give me a hint of what to check, I'll be grateful. Attached is my widget.
