Dave
Thanks for your comments.
<You_said>With MTS and COM+ specifically, CF can't declare a "transactional
page" like
ASP can, so you'll lose some transaction functionality.</You_said>
In my limited understanding of MTS, I think this is when an ASP pages
declares itself as the base MTS client. Have you hit this problem in
practice and determined a work around? Maybe you could create a proxy base
MTS client and pass all object calls through this (sounds a bit of a mung) ?
Perhaps Allaire are fixing these issues for a subsequent release of CF.
I'd like to be able to use the powerful features of n-tier dev without
having to go back to ASP.
