Hi,
It is not exactly the easiest to follow exactly what you have a
problem with. Guess that may be why no-one has come to the rescue.
You should strip your code and your question down to the root issue.
This makes it much easier to follow your reasoning, plus it show that
you have "done your homework", which is always a good thing.
For example. Issues with saving HABTM records has nothing to do with
Ajax. If it works without Ajax then you probably have a problem
related to Ajax and not specifically HABTM associations.
What specifically are you trying to save? (Model+assoc?, just the
assoc?, multiple assoc?)
What is the association you are having a problem with? (I.E. if User
HABTM Favorite why mention Eitity at all?)
Is the association working? (I.E. manually pushing data into the
database. Does it link up OK in the Models?)
Also, if you make a test setup without ajax, behaviors and anything
but form->controller->model you have eliminated a bunch of variables
and probably made the code more readable to others.
try to clarify and hopefully I (or someone else) may be abel to
understand your problem and be of help.
