Re: [udig-devel] refresh a catalog item
|
Hmmm. I'm afraid I'm not sure what is happening. There is some
caching of labels in the CatalogUIPlugin I think but I didn't think
that would affect the structure of the tree.

Let me add something more: I debugged down the line and before
returning
from the most top members(monitor) method (i.e. the IService method),
the array contains all the needed resources, which means they are
read.
The problem is, they are then not visualized. It "remebers" the
previous
tree. How can that be?

Yes, I also think the ResetService could work, I just have to
struggle
with the fact that when I reload (i.e. remove and redrag into
catalog)
the JGrass service, it doesn't call the members method of the nested
resources. Instead when udig restarts it goes indeep again. Is there
some memory somewhere or is it my fault?

Hi,
THe ServiceFactory.acquire() method creates a new instance of the
service but does not affect the catalog. It is just a factory. You
could probably do a find on the catalog for the service you want to
replace. Delete that service from the catalog and then put the new
instance in the catalog. I have used the ResetService and can
verify
that it does do something. I think it even works :P.

Finally I got time to get into this and...it doesn't work.
I'm trying to understand if it all depends on a strange
behaviour that I
notice. Perhaps someone can explaint that:
I open udig drag a grass location into the catalog and it reads
everything properly. So for example I have a location with two
mapsets
and nested inside the maps. Now I create a map in one mapset. I
remove
the service from the catalog and then drag the location into the
catalog
again. i thought it would read the whole thin g again, but it
remembers
something and the new map is not seen.
If I reastart udig, the map appears. So what does it remember
and where?
For your info the part:
IServiceFactory locator = CatalogPlugin.getDefault()
.getServiceFactory();
List<IService> rereadService = locator.acquire(ID,
connectionParams);
in fact creates a proper service, but without internal members.
But by
triggering manually the members method on the members fills
everything
down the tree, so that should work. (in fact it doesn't since it
remembers the old tree)
Any hint?

Trying to remember. Take a look at the ResetService class. It
essentially kicks the service so that the tree will be loaded
again.
Remember that there is a chance that there is a bug with
regards to
multi-level services since you are the trail-blazer here.

I need to add a created map to the catalog. That is easy with
shapefile
or so, but I can't figure out how to do that in a multilevel
service,
i.e. I want to add an entry to the JGrass location service,
which is
something similar in the level management to the WMS service.
Do I have to re-read it and if yes how do I trigger the re-
read of a
service? Is there a more performant way?
Ciao
