From the release notes
I saw the new feature called pooling.
|WJ-8809||New Feature||Support automatic polling to emulate push updates without WebSocket.|
Perhaps this might help you to update your client, when no WebSockets are available.
is your server running on WebSocket ?
Did those hints not help you yet ? http://wisej.com/support/question/showing-a-loading-spinner#sabai-entity-content-5403
The code I'm using to get a showLoader displayed on a button is this one. Not all the buttons work as you like, sometimes it appears sometimes does not appear. this.Button.call("showLoader"); Application.Update(this); Thanks
