grass_nviz.LoadSurface not returning id when called a 2nd time

[cmbarton]

This item may fix a number of things.

If you start wxnviz and display a map, close wxnviz, restart nviz...

The 2nd time you start wxnnviz...

id = self.nvizClass.LoadSurface(str(layer.name), None, None)

in nviz_mapdisplay.py is not returning the id of the map. It returns only -1. It's got the name right in both cases. But it returns an id value the first time it is run, but not subsequently.

This is at line 477 of nviz_mapdisp.py. I'm not sure, but it looks like a SWIG call in grass_nviz.py.

Because this does not return an id value, a lot of other things begin to bomb.

I am unable to reproduce it, probably I am doing something.

1. add raster layer elev_state_500m
2. display in 2D mode
3. display in 3D mode -> id 110658
4. quit 3D mode
5. switch back to 3D mode -> id 110658

This is fixed in 6.4 and 6.5, but still broken in 7. I'm changing the milestone so that it is no longer a problem for the GRASS 6 series. We probably just need to port the fix (I don't remember what it was) from 6.5 to 7.

This now seems completely fixed in 7.0 too. No one else has talked about it and it works for me. I'm closing it.
