Samuel Isokpunwu closed WSCOMMONS-191.
--------------------------------------

    Resolution: Fixed

Took a different approach that resulted in no code changes in the Axiom code.

> I think that attachment file deletion is an Axiom concern.
> The PartOnFile object creates the attachment file.  But I cannot find any code that 
> deletes the file.
> Here is one idea:
> Change the code to introduce a new object, CachedFile.
> CachedFile will create the attachment file when it is constructed and 
> delete the cached file when garbage collected.
> PartOnFile and CachedFileDataSource will be changed to use the CachedFile object.
> This will gurantee that the CachedFile (and thus the attachment file) will exist as
> long as it is needed.
> Any other ideas ?
