annotate flys-client/src/main/java/de/intevation/flys/client/server/RiverInfoServiceImpl.java @ 5818:a4ff4167be1e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Request feature info on all layers and show it as html if the server does not return valid gml. Non queryable layers produce an error message when the request fails. This is good enough
