Hello,
I have a WAB application which is used by a helpdesk team and it shows a layer that contains a lot of incidents.
At the moment I have 2 different layers for them in the webmap.
One layer contains all incidents regardless the type of information.
Another layer is already filtered through the MXD to show only last week's incidents.
Aside those two layers, I've added the filter widget to enable them to filter the complete layer (which is not shown by default at startup).
This situation of two similar layers causes a lot of confusion and not user friendly!
