Re: [udig-devel] deletion bug in uDig1.2-RC3

[Ivano Malavolta <i.malavolta@xxxxxxxxxxx>]

I debugged and checked the list of layers in either the case in which
I have the problem and the one in which everything is ok.
The inner list of layer is the same in both cases and it is perfectly
aligned with the list of layers provided in the Layers view.

So, now I am wondering if it is just a matter of naming. I mean, does
uDig keep track of the names of the used layers and it does not
refresh it?
