SQL Worker and redraw. a subform
Hi all,
This is for Omnis 10.22 and remote forms.
I’m new to SQL worker. When stepping through the methods I can see that the lists are populated correctly but they are not drawn on the screen.
According to the Omnis documentation a call to the server is needed but how do I do that?
When I click on a tab and then click back the lists are shown so there is an issue with redraw.Regards,

Hi Per-Arne,
Since the worker do their job on the server side, the $completed method of the worker would need to send a push to the client for synchronising the data. See also: https://www.omnis.net/developers/resources/onlinedocs/WebDev/02jsremoteforms.html#push-connections
Hope this makes sense.
Best,
Andreas

Thanks, that actually helped point me in the right direction.
I ran into something similar recently and the key for me was exactly what you mentioned to https://www.omnis.net/developers/resources/onlinedocs/WebDev/02jsremoteforms.html#push-connections. Nothing updates on the client unless you explicitly push it. In my case, adding a push from the worker’s
$completed
and then forcing a redraw on the client side did the trick.Per-Arne, you can try something like triggering a client method via push that calls
$redraw()
(or refreshes the subform/list) once the data is ready. Without that, the UI just sits there with the old state until something else (like switching tabs) forces a refresh, which is what you’re seeing.So yeah, it’s not that your list isn’t populated—it’s just never told the client to repaint.
