WAB: attribute table not loading

[FrancescoTonini2]

Hello everyone,

Recently, I have been having issues in my WAB-based web application when trying to view the attribute table of any layer in it, no matter whether that data is pulled from AGOL or from a local shapefile. Keep in mind that I am testing this with data where there is a small number of features in it. The attribute table (attached image) show a buffering/loading GIF and no table is pulled up. Do you have any idea what can be causing this? I checked my remote server and RAM is running at 40%, CPU < 10% so does not seem to be related to any overhead issue. Any help troubleshooting is much appreciated!

Thanks for letting me know Jeff! Please if you find out what's causing it and how to solve the issue, please post it here! I am still dealing with the same issue! Thanks!

Everyone, the final solution, if you encounter a similar issue in WAB2.5 is to try upgrading to WAB2.7 and re-deploy the web application. The attribute table now seems to work just fine as it should.

Different solution I found to an attribute table not loading is to up SOC heap size. This did the trick for me (dealing with some hefty datasets) Geoprocessing service settings: Advanced properties—ArcGIS Server | Documentation for ArcGIS Enterpr...
