Re: Shouldn't saveAll remove associated records as well?

Negative, once again you are not using cake model as it is intended,
if you really truely want to have this behavior ... you need to have
the following setup ...

tables
-----------
articles
tags
articles_tags

associations
--------------------
article HABTM tag
tags HABTM article

set the unique variable to true in the association

now when you do a saveAll, any current tags associated with the
article will be deleted first, then the ones you have selected before
the saveAll will be inserted into the articles_tags table, thus
effectively deleting any tags you odn't want anymore ..
