ContentInterceptor.postStoreContent() provides no content data

[Alex Soto <as...@opux.com>]

Hi,

I was playing with ContentInterceptor and trying to access the content 
of the revision in postStoreContent().  What I've noticed is that 
NodeRevisionContent.getContentBytes() is empty in the postStoreContent() 
method, but has data in the preStoreContent() method.  Not sure if this 
is a bug, but since the javadoc didn't mention this, I thought I'd let 
people know.

This  is a known problem. The content is accessable via a InputStream, so 
after storing the content, the stream is empty. You can access the content in 
preStoreContent, but you have to make a copy of the content in a 
sophisticated way and set this copy afterwards so that the content still can 
be stored.
Try to avoid to copy very large resources into memory, this would limit the 
content size to your available memory size.
I'm currently working on events as a replacement for interceptors and I'll try 
to give a hint how to workaround this problem in future releases.
