Difference between updateContent() and deleteContent() + addContent()?

[Thomas Ehardt]

In the context of "replacing" a TIFF image (base part, only part),
what is the difference between calling updateContent() vs.
deleteContent()/addContent() on a CMBDataManagement object?

We've run across a couple of instances where updateContent() appears
to have allowed the update to happen, but then threw a CMBException.
When we tested the same documents with delete/add, we had no problems.

We are running CM8.2 on 390 library server and Win2* resource
managers; our documents typically consist of a single multi-page TIFF
+ annotations/notelogs.

regards,
Thomas

Thomas,

 

It's been a while since I have looked at that API but I think the difference between the replacing vs the delete/add is that the replacement method is meant to preserve the original item id for the part for the object. Doing it the other way creates a new part with a different item id. I don't know what exception you're getting but I have used them both reliably in the past.
