a workaround, I have done the same fix in my code i.e. backup the connection
type and change the connection type to MS_INLINE just before calling
whichShapes(). After the change, it is retrieving the attribute values.
Appreciate your help.<o:p></o:p></span></p>

following issue here:<br>
<a href="http://trac.osgeo.org/mapserver/ticket/2689">http://trac.osgeo.org/mapserver/ticket/2689</a><br>
<br>

Make sure your version is newer than the changesets above.<br>

By using this fix you won't need to call layer.open right after whichShapes in
order to retrieve all the items.<br>

<p>Hi<o:p></o:p></p>
<p> <o:p></o:p></p>
<p>I am having difficulty performing layerObj.whichShapes() and looping
through results. For some datasets like shape files, it requires
layerObj.open() call after invoking whichSpaes(). Otherwise,
shapeObj.values.length is 0. For ArcSDE, it throws an error on
layer.nextShape() if layer.open() is called after invoking whichShapes(). How
to write a single piece of code that works with all datasets without checking
for layer data source type? Here is the simple test code I am using<o:p></o:p></p>
