Ui_form ignores socketid?

updates from one socketid get sent to/are accepted for all socketids...
On the other hand, if you click the submit button on the form, the fields get cleared, but not for the other socketids...

I know there is a fork mdashboard, but it's not been updated for 3 years, and I als would like to use the UI_LIST (listbox, but not dropdown) and the 2 don't seem to work together.

example (open 2 windows, click on the button and watch the other form change as well.
the message from the button does contain the correct socketid...
