Managed to solve this one.Here are my findings:
InternalRenderMetricsFactory.canRender
would return delegate.canRender(context). The problem was that
delegate was of type RasterRenderMetricsFactory instead of
BasicWMTRenderMetricsFactory.
Upon further inspection I found that
just checking the
net.refractions.udig.catalog.wmt plugin in run
configurations->plugins does not require for the
....render.wmt.basic plugin to be included. So if you check the
catalog.wmt plugin and then click the “add required plugins”
button you will not get to see any wmt layer and you will also not get
any error message that may give you the idea that a vital plugin was not
included. You'd think that if the catalog.wmt plugin was included
the user would want to see some wmt layers onscreen :). Newbies (like
me) beware!
Cheers

Subject: [udig-devel] Wmt georesource is not rendered. Why??
Hello all,
I'm encountering a very frustrating
problem. I am trying to render a mapnik layer using eclipse 3.7.2
with udig sdk 1.3.1. Using eclipse 3.6.1 with udg sdk 1.2.1 and
executing the exact same code the mapnik layer renders correctly .
So map.sendCommandASync(newAddLayersCommand(theres));
w
returns different results in what seems to be virtually identical
cases; by the way “theres” has the following content ( in both
run cases) :
[WMTGeoResource(wmt://localhost/wmt/net.refractions.udig.catalog.internal.wmt.wmtsource.OSMMapnikSource#blank)]
Some
other observations:
1.
in
the non-rendering case the console output is
!MESSAGE
Unable to parse version from about.mappings file. Defaulting to a
blank string.
log4j:WARN
No appenders could be found for logger (org.geotools.factory).
log4j:WARN
Please initialize the log4j system properly.

Please
give me a few tips on how I might solve this problem. I really want
to use an osm map in my little project. I would use the older udig
sdk but I can't seem to render a postgis layer using the older sdk
:)). It works in the new one. I think it has something to do with
the fact I have postgis 2.0 installed.
PS
@andrea antonello: I see that you have been working on the wmt plugin
lately.
Please
tell me you encountred these rendering problems. :)
Thanks
