Hello All,
I try to create a module from Sample here:
Display identify results in popup | ArcGIS API for JavaScript
but got error message on "mapPoint" of undefined. Not sure how you send the map click point to module?
or Do you have simple sample for creating a mudule using query or identify? Thank you.
