Re: [udig-devel] Protecting Catalog Services
|
Hi Dave,
A good question. What should happen (but I know doesn't) is there
should be a BIG warning message and each map should have that layer
removed from the map. Right now it is a bit more dodgy than that.
I've made a task for this issue and will try to make a resolution for
this ASAP. But since there is code freeze it will be for the 1.1.1
patch.

Is there a way of protecting services which have been put in the
local catalog, i.e. stopping the user from removing them? It seems
that, if the user deletes a service, all layers from that service
will fail on existing maps which use them - even if your plugin
always makes sure the service exists on startup (and creates it if
it doesn't).
Here's an example;
1. Open up uDig, create a new project and map.
2. Drag the Grid layer from the Map Graphics service on to the map
3. Delete the Map Graphics catalog entry
4. Close uDig, then re-open it
The Grid layer won't render ("There was no renderer found capable of
rendering this layer") and in the layer properties, the ID of the
layer is "mapgraphic:/localhost/mapgraphic2#grid" rather than
"mapgraphic:/localhost/mapgraphic#grid". No amount of refreshing or
opening and closing of maps or uDig will get it back again. If you
create another map, you can add the Grid layer (from the recreated
Map Graphics service) to it without problems.
I know it's unlikely that users will delete these services, but
there doesn't seem to be any way of recovering from this situation
if they do. I'm just trying to put this into JIRA, but I'm having
problems connecting to your site (probably my dodgy internet
connection!).
