When a map is created with arcgisutils “createmap” function and when we add a feature layer dynamically with SELECTION MODE, the features returned by “selectFeatures” method disappears as we click anywhere in map.
Steps:
- 1) Create map using arcgisutils.createmap function
- 2) Add layer in SELECTION mode once map is created
- 3) Now using drawtool select area on map
- 4) You will see the selected features on map now.
- 5) Now click anywhere on map and you will notice that the features disappeared from the map.
The same scenario works when map is created with ARCGIS esri/map class.
