Neatline Maps 1.0.0: geotiff error

I'm a complete newbie to this list so don't hesitate to let me know if there are ways to improve my potocol.

I installed the new NeatlineMaps plugin 1.0.0 . I am using Omeka 1.5.1. I was able to point to my server with the workspace: neatline . Omeka reports that the server is 'active'.

Now I have uploaded a geotif as an item, which you can see at . As you can see at the bottom of this items page, php reports an error:

Fatal error: Call to a member function attributes() on a non-object in /var/www/omeka/plugins/NeatlineMaps/lib/GeoserverMap_WMS.php on line 172

My php learning adventure has just begun. If anyone out there has any tips for me, please advise.


Update: I have observed that adding the geotiff as an item in Omeka does cause a layer to be created in geoserver. The problem is that Geoserver is not able to create the SRS for the layer from the information that is in the geotif. It can't do it when I try to add the geotiff dierctly in geoserver, either. So adding the proper SRS in geoserver seems to make the Neatline-Created layer previewable. I still have not been able to view the layer in Omeka/Neatline though, because now my geoserver keeps crashing!!! Perhaps it is a memory issue brought about by the new geotiff layer. More later. Thanks

Memory could be an issue. Administrating GeoServer (or any Java Servlet application) is usually, well, a learning experience. But as a general rule, they do best with lots of memory.
