Refresh layer info in widgets

Idea created by aimong on Jul 17, 2015

    This idea has been merged with Web AppBuilder - Add a Refresh Widget.

    Some widgets (attribute table and layer list specifically) do not update layer information if the layers were changed in the web map after the widgets were configured in the application. You must build a complety new application if you change the layers in the web map. A lot of work goes into setting up an application.
