Hi all,
When using uDig and Geoserver via WFS with an Oracle datastore I have noticed that some features are not being rendered. Attached are 2 images, both of the same geographical area in rendered in uDig. The first has some points missing, some of which I have crudely highlighted with red circles. The second is as a result of closing and reopening uDig to re-render the layer. It also has some points missing but they’re different ones. Previously I have seen the same issue with the lines. They’re fairly easy to spot in these datasets because the point dataset was created by extracting all the nodes from the line dataset so the two should match perfectly and occasionally they do but not always.
How can I tell which is missing them, Geoserver, uDig or Oracle?

Hmmm... another mysterious issue... Again tough to say where the problem lies... The only thing I can think of doing is watch the geoserver logs and try to catch a request log that occurs when you see a missing point.
Then maybe run the sql against the database to see if the point is fetched out of the database.

Very hard to tell indeed. Maybe with a debugger I could look into this,
but I would need the dataset, and the luck to reproduce the issue.
