If you're cool with looking up the snippet by class/method name use the
plain old snippet. If you want some control before the method gets
invoked (e.g., changing the behavior based on current session state),
use the dispatch snippet.
Is there a quick explanation somewhere that is *up-to-date* on how to do
one-to-many bidirectional relationships and many-to-many bidirectional
relationships in the mapper? I've looked around but I'm not sure how it
all works.
There's no much to say about many to many other than HasManyThrough
which is a pretty old and crunchy piece of code.
One-to-Many is:

[Lift] lift-paypal module
Guys, I've spent some time gutting my extremely boiler plate paypal code now its in master. I've only implemented the PDT data types and response so far, but im going to do IPN tomorrow / over the weekend. So then, its all properly immutable now and is just generally a lot more sensible. To use it from a snippet you do this: val pdt: PaypalDataTransferReponse = PaypalDataTransfer(MyAuthToken,S.param(tx)).execute The default points to the sandbox, so to make it work with live you need to do: val pdt: PaypalDataTransferReponse = PaypalDataTransfer(MyAuthToken,S.param(tx)) .withMode(PaypalLive).execute When you have your PDT object, and just simply want to see if the transaction was a success or not you can do: pdt.paymentSuccessful // gives boolean result Would love to hear any thoughts people might have at this stage :-) Cheers Tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

Erik Engbrecht wrote: I haven't tried this, but if possible I'd suggest moving them into a separate libary and only letting NetBeans see the compiled jar. Unfortunately, that doesn't work. Anything that is seen as part of the project is parsed. So, I can't edit the Lift Example code because it refers to the Lift Textile parser (even though it just refers to the JAR). As a side note, I bet the Eclipse plugin has the same problem. They are both use pieces of Scala compiler, and anything that makes the compiler work hard makes the IDE work several times harder, because new stuff is continuously being pushed through pieces of the compiler.

Perhaps require the user to implement the IPN trait in there custom handler so they can then program it however they want (update the database or whatever) b) A similar mechanism to the PDT stuff to make the IPN verification callback to confirm the post data.
