@apmasmelar_UDFJC - thanks for bringing this up. I checked your MV and ExB settings, and all configurations should be fine. It appears that the problem may have something to do with the second Coordinates widget here:
In this widget, the added special SR does not support the mouse-hover-to-obtain-coordinate action, which might cause the popup not to show up.
If you remove the second widget or add a new one with SR supporting mouse hover, e.g. 4326, it works fine:
We will take a look at this special case. Thanks for the sample app.
