           Summary: On adding class item to layer (tutorial), map preview
                    errors out
           Product: MapLab
           Version: 3.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: map editor
        AssignedTo: maplab-dev at lists.maptools.org
        ReportedBy: ad_wells at hotmail.com


I installed ms4w yesterday on Windows XP Professional 2003.  I downloaded the 
MapLab application and proceeded to run the 'Maplab 2.2 Getting Started' 
tutorial.  When I got to 'Selecting the class item field' (MapEdit), at step 
4, the map preview pane opened up, but instead of seeing the map, I got the 
following error messages:

Warning: [MapServer Error]: msDrawMap(): Failed to draw layer named 'land_fn'. 
in C:\ms4w\apps\maplab-2.2\htdocs\mapedit\preview.php on line 469

Warning: [MapServer Error]: msDBFGetItemIndex(): Item 'CAPITAL' not found. in 
C:\ms4w\apps\maplab-2.2\htdocs\mapedit\preview.php on line 469

Warning: [MapServer Error]: msInsertHashTable: Invalid hash table or key in 
C:\ms4w\apps\maplab-2.2\htdocs\mapedit\preview.php on line 469
(above message 10 times!)

Fatal error: Call to a member function on a non-object in C:\ms4w\apps\maplab-
2.2\htdocs\mapedit\preview.php on line 474

>From the second error message, it seems to be related to trying to access the 
DBF field.  I ran the tutorial to this point twice, just to ensure that I had 
not done something wrong prior!  The only deviation to the instructions that I 
made was to key in 'popplace.shp' for the data field of the 'capital' layer 
object, as when I tried to select it using the browse button, the following 
string was returned, which did not reference the popplace.shp file correctly:

../../../../../../../..//maplab-2.2/tutorial/data/popplace

By the way, my downloaded version of Maplab is 2.2, why is this not a choice 
in bugzilla bug reports?  I had to choose either 2.0, 2.1 or 3.0.

Thanks in advance!
