Hi Martin,
thank you for the answer.
I am aware that I can build single Spatial queries and then wrap them up
with Logic object (using OpenLayers Filter classes) and thats how my gxp
plugin works at this moment. So if I have several features will it be more
efficient to
- query a layer against one generic collection or
- pass collection of Spatial filters (one filter corresponds to one
feature) with a Logic wrap round it?
Thanks Alex
