Is there any technique for triggering the web browser to update (repaint) fields as their data values are changed on the server side, i.e. without user interaction?
It is possible to accomplish this by using a ProgressIndicator which periodically polls the server for changes. For a discussion and some examples see the
server push discussion in this forum.
IT Mill Toolkit does not have built-in support for server push at the moment. As far as I know, it can be done with GWT and some servlet containers, but it’s hard to say how easy it would be to implement it for IT Mill Toolkit. There’s a long-standing ticket for this at
