Jackie I've created a monster...... something is wrong with the FeatureReader that is produced from the layer .... i think?
It seems to be retrieveing all features from the featuresource .... the layer has a filter assigned that grabs only some features from the featuresource... If you or anyone is able to have a looky it would be great ! requires ajaxcontroltoolkit. I can zip up the project if required and post it here.
