[Chameleon] maptips problem

[Hiten Ravani]

Hi 

I am trying to use maptips in my application , but i am getting the
following errors. 

Warning: Invalid argument supplied for foreach() in
/path/to/chameleon/htdocs/widgets/LayerAttributes.php on line 188

Warning: array_keys(): The first argument should be an array in
/path/to/chameleon/htdocs/widgets/MapTips/MapTipsPopup.phtml on line 83

Warning: Invalid argument supplied for foreach() in
/path/to/chameleon/htdocs/widgets/LayerAttributes.php on line 188

Warning: array_keys(): The first argument should be an array in
/path/to/chameleon/htdocs/widgets/MapTips/MapTipsPopup.phtml on line 83

(PS : path/to chameleon has been edited in the above warnings)
-------------------------

I am basically using the same code provided in the tools_enhanced.html (in
the samples/htdocs folder)

Here is a sample of my Layer definition from the mapfile. 


 LAYER
      NAME mainrivers_layer
      GROUP mainrivers
      METADATA
        "wfs_title"    "Main Rivers"
        "wms_title"    "Main Rivers"
      END
      CONNECTIONTYPE postgis
      CONNECTION "dbname=? host=? port=?" 
      DATA "the_geom from mainrivers"
      STATUS ON
      TYPE LINE

      PROJECTION
         "init=epsg:4326"
      END
      DUMP TRUE

      TEMPLATE "ttt_query.html"
      TOLERANCE 2
      TOLERANCEUNITS PIXELS
      CLASS
        STYLE
          OUTLINECOLOR 0 3 255
          SIZE 5
        END
      END
  END #end main-rivers

(PS : I have replaced the database connection parameters with ? )

I don't know much abt php so wasn't able to track down the exact problem.

Any help in solving this problem is greatly appreciated.

Regards,
Hiten.
