I have create a text input type header render for datagrid as a filter. On change event I am dispatching my custom event which refresh the datagrid from
server side filter but in this the text input in which I am typing lost focus and gain it again on mouce click
Alreadt tried setFocus and focusManager
I'd probably wait for updateComplete and then call setFocus again. And/or
use callLater to defer setting focus.
