I'm new to Craft and VERY new to plugin development. I'd like to display a thumbnail image in my table list view and thought it would be possible to accomplish using a new Custom Element Type. Does anybody know how to achieve this?
I have managed to output custom fields in the table using defineTableAttributes() but I can't output any related Assets - in particular their filenames. Do I need to define a relation in the ElementCriteriaModel using the defineCriteriaAttributes() function? Can anyone explain how this is done?
