[mapserver-dev] DrawQuery with Oracle Spatial -RFC 52(?)

[Pano Voudouris]

Hi All,

I originally posted this on the MS4W list but they advised I should send it
here. I seem to have a problem with MapServer 5.6.3 DrawQuery request on
oracle spatial layers (native oracle connection). I am working with
mapscript csharp (ms4w 3.0-beta11)
The error is: 
 
 msDrawMap(): Image handling error. Failed to draw layer named 'STREETS'.;
 msOracleSpatialLayerResultGetShape(): OracleSpatial error.
 msOracleSpatialLayerResultGetShape record out of range
 
 The bit of code that gives the error is:
 
 layerObj active_layer = aMapObj.getLayer(active_layer_index);
 active_layer.open();
 resultCacheObj results = active_layer.getResults();
 imageObj image=aMapObj.drawQuery(); // This throws the error
 
 I also tried using the layerObj.DrawQuery but this gives a different error:
 
 msOracleSpatialLayerResultGetShape(): OracleSpatial error.
 msOracleSpatialLayerResultGetShape called on unopened layer (layerinfo)
 
 although the layer IS opened!
 
 Code is:
 layerObj active_layer = aMapObj.getLayer(active_layer_index);
 active_layer.open();
 resultCacheObj results = active_layer.getResults();
 imageObj image = aMapObj.draw();
 active_layer.drawQuery(aMapObj, image); //This throws the error
 
Does this have to do with RFC 52? And is there a workaround?
 
BTW, the open/close layer methods seemed to be required on the 5.6.3
version? I
didn't have to open the layer in 5.2.1 (ms4w 2.3.1). If I don't open the
layers I was
getting the unopened layer error even on shapefiles.
 
Thanks,
