Re: [udig-devel] deletion bug in uDig1.2-RC3
So no real idea; if I remember your description you are having trouble adding a layer again. I don't see any logic in the New Layer action.

Let us try in ApplicationGIS. The method addLayersToMap has the following:

        /*
         * Check or not for duplicate layers in context of the map where georesources are added.
         */
        List<IGeoResource> cleanedGeoResources;
        if(ProjectPlugin.getPlugin().getPluginPreferences().getBoolean(PreferenceConstants.P_CHECK_DUPLICATE_LAYERS)){
            cleanedGeoResources = ProjectUtil.cleanDuplicateGeoResources(resourceList, map);
        }else{
            cleanedGeoResources = resourceList;
        }

I would put a break point there and see what is going one; not sure I understand why the check is there.

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

Okay so you are working as a developer then; can you step through with a
debugger and see what is different about the two ways of doing things? The only
thing I can think that would mess things up is if the same *instance* was added to > the layer list twice?

Hi Jody,
I tried with a layer coming from a shapeFile (as you did) and actually
the bug did not come out.
I think it is related only to the layers created inside uDig. I tested
with layers created both manually through the "create new layer"
action
and via other plugins (for example the layers resulting from a spatial
operation) and the bug showed up.
Can you confirm that?

Best,
Ivano


Sure I can look at that; when you say Layer called "A" are you renaming the layer - or is the layer name created from the source data (ie shapefile name or
wms layer title?).

I went through the steps you describe using "cities.shp" rather then "A" and was unable to reproduce the problem.

Hi all, I think I just discovered a bug in both uDig1.2-RC2 and
uDig1.2-RC3, I have the suspect that uDig does not
propertly delete resources (i.e., Projects, Maps, Layers) from the
Project and Layer view.

Here is the workflow to reproduce the bug:

1) create a new Layer called A;
2) delete the just created layer A;
3) try to create a new layer called A.

At this point uDig does not allow to create the new layer because the
layer is still in some internal data structure of uDig.

Can somehome try to reproduce the workflow and confirm me the
existence of the bug?
Is there a straightforward way to fix it?

Cheers,
Ivano
