You can see that _NET_WM_STATE doesn't include and NET_WM_DESKTOP is 0, so
there is nothing in AWN window that instructs the window manager to set it
sticky.

FYI, the same problem shows in KDE (kwin) too. I believe AWN is not using the
standards (EWMH) ways of setting its window sticky but rather relies on
specific implementation that set dock windows sticky by default (which is not
specified by the standard) - I do not see why docks should be necessarily
sticky...

FTI, both metacity and compiz do treat docks as sticky, but neither kwin nor
xfwm4 do.

So this is a bug with AWN, not xfwm4."

To sum it up, he said that AWN does not do anything to tell the window manager that it should be on all desktops; all it does is set itself as a dock. The attached patch instructs xfwm to display all docks on all workspaces. He has not yet decided if it should be merged into the svn tree, but would not have to if AWN were standards complient.
