I'd like to throw in another question regarding the totally cool new
search index feature:

I build a map for my vista hcx that contains several layers with
different product-id: 2 different background layers (landuse/terrain
visualization), 1 main layer (routable ways, pois and minor polygons)
and layers for maxspeed, hiking routes, lighting etc.

Now I started using the index on the main layer and it works great -
as long as I don't try to combine all layers to a single gmapsupp.img,
which I always do by calling mkgmap with all sublayer gmapsupps as
input files:

java -jar mkgmap/mkgmap.jar --gmapsupp --nsis
--description="OSM-Topo-DE" --overview-mapname=topo-gesamt
deutschland/gelaende/gmapsupp.img deutschland/landuse/gmapsupp.img
deutschland/topo/gmapsupp.img deutschland/maxspeed/gmapsupp.img
deutschland/isohypsen/gmapsupp.img deutschland/isohypsen2/gmapsupp.img
deutschland/wanderwege/gmapsupp.img deutschland/lit/gmapsupp.img

When doing so now, the resulting gmapsupp.img is lacking the complete
main layer, but no error message is given.

When I add --index to the command line, I get the following error
message immediadely:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

Has anyone else tried to combine a layer containing an index with other yet?

I also observed (sorry if this is already known) that many streets
with highway shields generated from ref=* tags only appear as the
ref=* value in the street search, even though both ref _and_ name are
displayed by the device. Other parts of the same street appear only
with name=*.
(Example: ref=B 56, name=Euskirchener Straße in Bonn, Germany)
(using the latest patched version)

Thanks for answering (and all the great development work, of course)!
