James,
I got even closer some minutes ago.
My relationship to ERAttachment is named "erAttachment", so I used an
ERD2WDisplayImage component with the propertyKey "erAttachment.webPath", like:
100 : pageConfiguration = 'ListImage' => displayPropertyKeys =
("erAttachment.webPath") [com.webobjects.directtoweb.Assignment]
100 : ((pageConfiguration = 'InspectImage' or pageConfiguration = 'ListImage')
and propertyKey = 'erAttachment.webPath') => componentName =
"ERD2WDisplayImage" [com.webobjects.directtoweb.Assignment]
But webPath is not returning the full path, only the filename portion. This is
what I get in the HTML:
<img src="/0-1.jpg" id="erAttachment.webPath">
I'll be looking at the screencasts suggested by Ramsey, since I want to create
something like an "image grid" component... I'm gonna need a custom component
anyways.
Cheers,
Flavio
