I have a BrowseEntry widget that populates a Entry widget using the browsecmd. 
   $addRefdesListbox = $addRefdesFrame2->BrowseEntry(-variable=>\$sear
+chString,
-fg=> 'black',
-bg=> 'white',
-exportselection => 0,
-browsecmd => sub{$addRefdesEntry->insert('end',$refdesMaxValue{$searc
+hString}+1)},
-listcmd=> \&doSearch,
)->pack(-side=>'left');

If I change contents of the Entry widget {$addRefdesEntry}, I loose my reference to the BrowseEntry widget as shown when I try to do the following later in the program. 

$refdesListbox->see($addRefdesListbox->Subwidget('slistbox')->curselec
+tion());

The $addRefdesListbox->Subwidget('slistbox')->curselection() value is null if I edit the Entry widget. This yields the following error. 

Tk::Error: wrong # args: should be ".toplevel.frame.frame.frame.frame.
+frame1.frame.listbox see index" at C:/Perl/site/lib/Tk.pm line 228.
 Tk callback for .toplevel.frame.frame.frame.frame.frame1.frame.listbo

If I do not edit the Entry widget, program runs fine.

I would appreciate any insight into this. Thanks
