Deshe,
Have you tried in WAB Release Candidate 1 (only available on ArcGIS Online)? Have you submitted a bug on the Beta site for this? Until the application is fully released you can expect some language issues like this.
Hi Robert,
I'm using the WAB that is on AGOL, so I guess it's the Candidate 1 you wrote.
I talked to the ESRI Support In My country and they say that the problem is how ESRI save the features in their servers. The solution, for now, is to use features from my server and not hosted feature services.
I did that and now it works fine.
thank you for the response!
Dikla.
