[Seaside] Refload page on typing without losing focus?

[Esteban Maringolo]

Bob,

Who is "we" in your statement? :)

In any case, the overall interaction would be somewhat clumsy, because
you have to wait for the full page reload (AJAX or not) and then focus
the proper widget, it is not the same to lose the focus (blur) by
pressing tab, than by pressing a random element in the DOM.

I had to do the opposite, be able to update the content of a grid of
inputs without reloading them to preserve the expected keyboard
navigation, and I resorted to a set of helper JS functions that get
called in my event handlers (change, blur, etc). The result
interaction is very flluid.

In any case I don't see why you need to reload the whole page and not
parts of it.

Regards,

Esteban A. Maringolo

The on the refresh we include a load script that checks for a non-null onFocusWidgetId value which is not equal to document.activeElement.id and sets it using document.getElementById(onFocusWidgetId).focus(); ... similar logic is used to set the cursor position within an input field, otherwise the cursor is set to the start of the field, even if a user clicked elsewhere.
