I have a Webapp (WAB 1.2 Developer's Edition on my own computer with the layers hosted through ArcGIS Online) that uses the Attribute Table.
It won't load attribute table data, giving me an "Error performing query operation" error after about 30 seconds or so as well as occasionally being slow to load the data itself. Is there a way to get this error to not come up when using the Attribute Table?
It seems like the spatial data itself is having a problem loading - the data is published as a service on in-house servers. The web map loads fairly quickly on ArcGIS Online (including viewing the Attribute Table in the AGOL map).
