Christian,
You should set the classObj.template instead of the layerObj.template.
An empty template file should be sufficient.
How about your previous problem? I could not get your sample project
for reproducing it.
Best Regards,

> I try to query a point-layer in my c#-mapscript application. For that I write a function in my class Layer (base-class is layerObj) which should give me back a feature. I'm sure the point-coordinates I give in the function exists in the layer. But I got no result from the query. I think the reason could be the template. I red, that I have to set that propertie. So I create just create a html-document and set the propertie to it. Is there something that have to be in the document or is a empty document enough? What else could be the reason for getting no results?
