Subject: webstaff: Grid supports automatic refresh with query change
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=370a7d12a366ff26c4f354f6da96a86ace6e7252;p=Evergreen.git

webstaff: Grid supports automatic refresh with query change

Adds a new gridControls function watchQuery(), which returns the
contents of the grid query.  When the contents change, the grid
automatically redraws.
