I'm having a couple issues with the Web AppBuilder eSearch 3.3 and 3.3.1 widgets. Both versions are currently giving me a "Search Failed!" message.
I'm including a couple of video/screenshots that illustrate what is happening. A previous version of the eSearch widget worked well earlier in the week. Also the layer i am trying to search: http://gis.goshencounty.org/webadaptor/rest/services/GoshenWAB/MapServer/3 is able to be queried using the Query widget in Beta 3.
Version 3.3 the unique value list populates with the drop down, but gives me a "Search Failed!" error. http://screencast.com/t/evd7hYy3
Version 3.3.1 the unique value list will not populate, and if I type in a value I get the "Search Failed!" error.
