[ckan-dev] text_preview not recognized

[Hildegard Gerlach]

Hello,

I upgraded CKAN on Redhat to the master branch (shows version 2.2a in page source) and also the harvest and spatial extension.

ckan.plugins = stats text_preview recline_preview synchronous_search harvest ckan_harvester spatial_metadata
spatial_query wms_preview csw_harvester doc_harvester waf_harvester spatial_harvest_metadata_api resource_proxy
pdf_preview geojson_preview

If I susbtitute json_preview in my development.ini file with 
text_preview I get an error message in the logfile

   PluginNotFoundException: text_preview


but in setup.py I can see the text_preview extension.
If I put it back to json_preview CKAN comes up but if I want to preview 
json, I get

An internal server error occurred

and in the logfile

Error - <class 'genshi.template.loader.TemplateNotFound'>: Template
"json.html" not found


Thanks Hilde
