[udig-devel] Layer with NullGeoResource

[Ugo Taddei <ugo.taddei@xxxxxxxxxxxxxxxxxx>]

Hello,

I'm trying to programatically add a layer (from an Oracle DB). Though 
the code works in most circumstances, sometimes I see my layer with an 
OracleGeoResource (just before it gets added in 
AddLayersCommand.run(IProgressMonitor) ), have its georesource turned 
into a NullGeoResource(http://NULL).

The layer comes from an oracle view that gets created dynamically. The 
point is, when I run the code again, the layer gets added.

Am I missing something, like telling the Catalog to synchronize?

This is a tough one. I've tracked the problem down to 
LayerFactoryImpl.createLayer(IGeoResource) but I'd like to make sure I'm 
not missing anything before I dig further.

BTW, in LayerFactoryImpl.createLayer(IGeoResource), the line

layer.setGeoResource(preferredResource);

might yield

LayerImp.geoResource = null;

Does anyone want to have that? (Perhaps that's the reason for my problem?)

Thanks in advance,

Ugo
