T5: Issues contributing a coercion?
Hello,
I'm attempting to contribute a coercion. This is the first time I've
attempted to , so I could be missing something obvious...but the error
message I receive makes me think there's something else going on.
As you can see below, I'm attempting to coerce from
com.homeed.pages.EditPageModelImpl to com.homeed.pages.PageModel. It
says that coercion isn't available...however, look halfway through the
available list...this very coercion is listed!
Am I missing something obvious?
Thanks,
Andy

Create an interface for your page, make sure the interface is not in
the .pages. package, have the page implement the interface, do the
coversion in terms of the interface.
It's tricky class loader issues, the EditPgaeModelImpl class known to
your services layer is literally not the same class as the one
Tapestry uses to instantiate your page (once it gets down rewriting it
to fit in with Tapestry's runtime model).
