[fdo-users] RE: Which GML version is supported by FDO 3.5.0

[Brent Robinson]

Hi Crispin,

For the issue where the srsName changes from EPSG:4326 to Default in FDO 3.6, which provider are the features being read from? The srsName that is output is affected by the class definition passed to the XmlFeatureWriter. This class definition is retrieved from the FdoIFeatureReader passed to the xmlSerializer.

Brent.

I can confirm that. When the xmlSerializer has xmlFlags, but the xmlFeatureWriter does not, then xmlSerializer.Serialize should temporarily pass the flags down to the xmlFeatureWriter. This would mean that that application would only need to set the flags on the topmost object rather than on both of them.

Thank you Brent!

It is indeed about passing the xmlFlags to the XmlFeatureWriter and not to
the XmlFeatureSerialiser - even though the latter takes flags as an optional
parameter.
I can get the code to work now - if you confirm it would be your
understanding that the serialiser should also handle the flags then I'll
create a ticket.
