Whether strict parsing is enabled or not the parser will choke on anything that uses a namespace prefix on the root element that has not been declared. This is because we preparse body content to figure out what the request is in order to forward it on to the correct service. The way we do the parsing is to make it namespace aware which is why we get the exception.
I see two issues. The first is that OL is creating an invalid request plain and simple. The second is that geoserver could potentially turn off namespace aware pre parsing if the strict flag is not set which should make it lenient in this case. Feel free to open an issue report in the bug tracker for this. -Justin On Sat, Apr 2, 2011 at 8:49 AM, Serge Markin <[email protected]>wrote: > Hi All, > > > I am trying to build geospatial application using OpenLayers and > Geoserver 2.1-RC3.
