Some ActiveRecord/Monorail upgrade woes

[bittercoder]

Hi All,

I've recently upgraded an old ActiveRecord/Monorail application to
ActiveRecord 2.0 (RTM) & Monorail trunk.

Everything went pretty smoothly - but I'm now getting some data
binding issues when using [ARDataBind] - as part of the upgrade I now
have to specify what proxy factory NHibernate should use, and it seems
like the proxy is causing some unwanted side effects when it comes to
binding? Interestingly - swapping between Linfu and Dynamic proxy
also changes the nature of the error, as below...

If I use LinFu dynamic proxy w/Nhibernate, I get an exception thrown
on invoking an action with an [ARDataBind] parameter:

Castle.MonoRail.Framework.MonoRailException: Error processing MonoRail
request. Action Save on controller Product --->
Castle.MonoRail.Framework.MonoRailException: Error building method
arguments. Last param analyzed was product with value '' --->

stack: found Seller, expecting Product

Closest thing I could find related to this issue was:

http://markmail.org/message/zcqsbvywmjx267gg#query:Unexpected%20item%20on%20the%20stack%20castle%20project+page:1+mid:2vktx5aqxoc3j3hm+state:results

But that was related to a class where GetHashCode/Equals was
overridden, where as my ActiveRecord models don't implement either of
those methods...

Now, If instead I use Castle Dynamic Proxy w/ Nhibernate the Action
does not throw an exception, but I get a data binding error:

"NHibernate.Proxy.INHibernateProxy.HibernateLazyInitializer" => "node
is not Composite but still need to recurse to
Proxy.INHibernateProxy.HibernateLazyInitializer"

Closest thing I Could find related to this issue was:

But this was fixed in Trunk ages ago...

Any thoughts/suggestions on what my problem might be? We have other
projects running off Monorail/ActiveRecord trunk without issues.
