I am using Tridion 5.3.
I have webpage that has over 100 pdf links attached to it. When I publish that page not all pdf get published even though I get a URL for each pdf like "/pdf/xyzpdfname_tcm8-912.pdf". When I click on those links I get a 404 error. For the same pdf components for which I get the error, if I publish them by attaching 5 to 10 pdf at a time they get published and there is no 404 error and everything works fine. But that's not the functionality I need. Does any one know why Tridion is not able to deploy the binary contents if I publish them in bulk?
I am using engine.PublishingContext.RenderedItem.AddBinary(pdfComponent).Url to get the pdf url.
Could this be to do with the naming of your PDF?
Tridion has a mechanism in place to prevent you from accidentally overwriting a binary file, with a different binary file that is named the same.
I can see the Binary you are trying to deploy has the ID:
tcm:8-755-16
and you are naming it as follows:
/www.mysite.com/multimedia/pdfname_tcm8-765.pdf
Using the Variant Id:
variantId=tcm:8-755
is it possible you are also publishing the same binary from a different template? Perhaps with the same filename, but with a different Variant Id?
If so Tridion assumes you are trying to publish two 'Variants' of the same binary (for example a resized image, obviously not relavent for PDFs)
The deployer is therefore throwing an error to prevent you from accidentally overwriting the binary that is published first.
You can get round this in 2 ways:
1> Use the same variant ID for publishing both binaries
2> If you do want to publish a variant, change the filename to something different.
I hope this helps!
