Re: [Lmappletserver-developers] Media columns in the MetaLogViewer

[Roberto M. <rob...@gm...>]

Hi Peter,

I agree with your comments. One small thing though, when I sad entry_id 
I meant object_id. I have to get the object_id form the upload page 
because the addLogEntry needs it. And by using that I can easy create 
new folders or add files to existing ones. That is why I thought it is a 
better idea to use the object_id as folder coordinate. However, as 
things are now I add every file a random integer number at the beginning 
of the file when writing it to the FS and DB, so there is no problem 
with duplicate naming. Sorry once again for the miss leading and please 
tell me if my conclusion is fine.

Regards,
Roberto
