Re: [udig-devel] deletion bug in uDig1.2-RC3
|
So what I am looking for is this ...
Go through the steps of adding two layers, removing one, etc... using the user interface. Look using the debugger at the list of layers.
Do the same steps as a developer (using your tool?) and again look using the debugger now that the problem is there.
Tell me how the two differ? Then after that it sounds like you try and create the layer again; and it fails somehow? Can you use the debugger to show me where it is failing?
