| Thanks to both. I have not tried yet how to display the erattachment (i'll do it this evening or tomorrow), but... I managed to model "correctly" (maybe..) many photos: Product < -- >> ProductPhoto < -- > ERAttachment
This are my rules:
"100 : pageConfiguration = 'ListProduct' => displayPropertyKeys = (name,price,category,thumb) [com.webobjects.directtoweb.Assignment]", "100 : (pageConfiguration = 'ListProduct' and propertyKey = 'thumb') => componentName = ERD2WDisplayAttachment [com.webobjects.directtoweb.Assignment]", "100 : ((pageConfiguration = 'CreateEmbeddedProductPhoto' or pageConfiguration = 'EditEmbeddedProductPhoto') and propertyKey = 'attachment') => componentName = ERMD2WEditAttachment [com.webobjects.directtoweb.Assignment]", "100 : ((pageConfiguration = 'CreateEmbeddedProductPhoto' or pageConfiguration = 'EditEmbeddedProductPhoto') and propertyKey = 'attachment') => attachmentConfigurationName = Product.photo [com.webobjects.directtoweb.Assignment]"
So, now I don't get exception when I try to add or edit a photo. But... there is a problem: if I try to add more than one picture for a product at the same time I get an exception (and the output in eclipse is cut.. I don't know why). This happens also in the edit mode. If I add a picture, save the product, edit the product again, add another picture, etc, works.

About thumbnailing. What's wrong? I mean... if I read correctly ERAttachment framework should be able to find ImageMagick (I'll try later), but I don't know the "deployment environment", so I'd like to have my code to stay more.. general... Last thing about thumbs.. If I don't set er.attachment.file.filesystemPath = /tmp
I get an exception, because the processor cannot find the filesystemPath property... this happens also if I create the processor passing a configurationName..It just not save it.. I was wondering.. is this the right behaviour? Using pending attachment works...
@Override public void setAttachment(ERAttachment value) { // TODO Auto-generated method stub super.setAttachment(value); if (value != null) { try { File inputFile = new File(((ERFileAttachment) attachment()).filesystemPath()); File outputFile = File.createTempFile("erattachment-thumb-", attachment().originalFileName()); ERImageProcessor.imageProcessor().thumbnail(50, 50, inputFile, outputFile);
ERPendingAttachment pendingAttachement = new ERPendingAttachment(outputFile, outputFile.getName(), null, "Product.photo", null); ERAttachment attachment = ERAttachmentProcessor.processorForType(attachment().storageType()).process(attachment().editingContext(), pendingAttachement); attachment().addToChildrenAttachments(attachment); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } }
