I'd like to suggest better/more detailed error reports when WFS transactions fails.
My use case is that I've put a constraint in PostGIS st_isvalid(geom) = true which means that certain updates or inserts will be rejected. I'd like to be able to communicate to users what the cause of the error is, but from Geoserver (1.7.3) the below exceptionreport is as detailed information I can get - unless I'm missing something? My analysis of the current code is that the WFSException is thrown in UpdateElementHandler.java line 239 and then put togheter into a response in Transaction.java but the cause of the WFSException is only used for logging not the response. Wouldn't it be nice if the exception that caused the WFSException would be output into the response in some way (the first cause, at least) I'd be happy to contribute improvement, if I can and if this is something that you folks can agree is needed :) <?xml version="1.0" encoding="UTF-8"?> <ows:ExceptionReport version="1.0.0" xsi:schemaLocation="http://www.opengis.net/ows
