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

[Ivano Malavolta <i.malavolta@xxxxxxxxxxx>]

Hi Jody, in one of the tools I developed, I checked the layers list I
get from a the following instruction:

getContext().getMap().getMapLayers()

Here there are no duplicates and there is neither the deleted layer
(layer A in the example in the past mails).
Any idea?

Cheers,
Ivano
