Comment (by balagates):

 I noticed in the layer manager when a line with a d.vect "where" parameter
 is selected the status bar shows the d.vect command including the "where"
 and other parameters.  I also noticed that when you open a properties
 dialog (CmdPanel) for that vector the d.vect command is also shown in the
 dialog windows status bar but the "where" parameter has been removed.
 Debugging I see the "where" parameter is in the get_cmd() thru the end of
 GUI.ParseCommand() but it disappeared after the following code in
 ./gui_core/forms.py UpdateThread.run() is run.

 {{{
             pBind = self.task.get_param(uid, element='wxId',
 raiseError=False)
             if pBind:
                 pBind['value'] = ''
 }}}

 This may not be a bug by itself but seems related.  What I cannot find is
 a way for the "where" value imported by the Open Workspace to initialize
 the dialog "where" value.  The value I expect is destroyed in the above
 code but maybe the initialization should happen elsewhere?  As far as I
 can tell this aspect of the code has not changed since 7.4 and I thought
 this might have been working in 7.4 (not sure though).  Other parameters
 such as "icon" are not affected.  There appears to be special handling for
 SqlWhereSelect type parameters.
