mapscript error

Tue Dec 12 12:42:55 PST 2006

Hi guys,

I am writing a simple mapscript. This is what I am doing:

I have a layer where I draw counties. When a user clicks on map (I have 
the coordinates), I want to find which county it is. So I query the 
layer and I get one record back, so far so good. Then I call getShape 
method for the record. Now suddenly I get the error that the record 
number does not exist. I opened the DBF file and the record IS there.

Your help is appreciated. My script and error are as follows:

--------------------------------------------------------------------
Fatal error: [MapServer Error]: msDBFGetItemIndex(): Invalid record 
number 226. in C:\ms4w\Apache\htdocs\test.php on line 16
--------------------------------------------------------------------
<?php
dl("php_mapscript_4.10.0.dll");

$map = 
ms_newMapObj("C:/ms4w/apps/us_streets2005se-1/map/us_streets2005se-1.map");

$overlayLayer = $map->getLayerByName("countiesLayer");

$myApt = ms_newPointObj();
$myApt->setXY(-121.997, 37.348);

$returnVal = $overlayLayer->queryByPoint($myApt,$mapscript->MS_SINGLE,0);

$resultCache = $overlayLayer->getResult(returnVal);

$overlayLayer->open();
$overlayLayer->getShape($resultCache->tileindex, $resultCache->shapeindex);
// I am getting error on this previous line, getShape fails.
