handle of a file?

[Ted Vinke]

Hi!   I've got a builder named 'blob' which extends 'attachments', because it contains an additional field 'date'. Now I'm using it in the backend to upload files with it and I'm figuring out how I have to construct the url to the file on the frontend when I'm generating a list - so the browser can download it.   With the construction (where ${pfid} contains the startnode of type projectfolder):   <mm:list             nodes="${pfid}"             path="projectfolder,blob"             fields="blob.title,blob.description,blob.date,blob.number"             orderby="blob.date"             directions="DOWN"           >   I'm able to retrieve all information, but I found out the url /mmbase/attachments/session=cloud_mmbase+48294/TestDocument.xls would also need the actual name of the uploaded file, not just blob.title. But when I extends the fields attribute with blob.handle I'm getting a   javax.servlet.ServletException: SearchQuery...failed: ERROR: column blob.handle does not exist  errormessage. Since the original attachments-object has a handle, I should be able to acces blob.handle too right? How else I'm a going to construct the url to the file I want to download the file as in: /mmbase/attachments/session=cloud_mmbase+[blob.number]/[blob.handle] (here I ofcourse I'll have to use ${...} variables instead of [] :D)    Anybody an idea?   Regards, Met vriendelijke groet, Ted Vinke   First8 BV Groenestraat 294 6531 JC Nijmegen [EMAIL PROTECTED]
