[gdal-dev] Error when trying to create layer in FileGDB

[Even Rouault]

Casper,

I can reproduce. I tried a few things (including adding at hand definitions 
for MOrigin, MScale, MPrecision and LatestWKID that appear in the XML 
definition of the existing layer & feature dataset), but without success. It 
appears this is specific to creating the layer with FEATURE_DATASET=Data. 
Without that, it works. And there must be something specific to the SRS of the 
Data FeatureDataset too, because we have a test in the autotest suite that 
works:

    srs = osr.SpatialReference()
    srs.SetFromUserInput("WGS84")

    ds = ogrtest.fgdb_drv.CreateDataSource('tmp/test.gdb')
    ds.CreateLayer('layer1', srs=srs, geom_type=ogr.wkbPoint, 
options=['FEATURE_DATASET=featuredataset'])
    ds.CreateLayer('layer2', srs=srs, geom_type=ogr.wkbPoint, 
options=['FEATURE_DATASET=featuredataset'])
    ds = None

The joys of working with closed source software...
