reading and deleting annotation features in mapscript

[Mike Talbutt]

Hi all, 

A quick question from a mapserver newbie 

Using java mapscript I am creating annonations on a new map layer by
creating polygon features in a new layer, 

when I do a query on that layer to retreive the features I have created
I am unable to get at the shape objects as the following line of code
fails 

shapeObj shape2 = m_Layer.getFeature(resultMember.getShapeindex(),
resultMember.getTileindex()); 
            
, I noticed the tile index and shape index properties in the
resultCacheMemberObj object are both -1. Can someone tell me how to get
hold of the shape objects, as I need provide some sort of delete
annotation functionality, and I dont want to simply drop the entire
layer
