Kepler

By accident, I left a KeplerSlaveNode entry in the ecogrid registry. However when click refresh button in source window (you can click source button on data search panel to get), nothing will show up and here is the error:
ERROR (org.ecoinformatics.seek.ecogrid.SearchRegistryAction:queryRegistryRewriteConfig:227) problem merging new services with existing services

After I deleting this entry, the everything works fine.
