Ugh, my bad. I was wrong and confused this with something else (mostly the
@Create page param problem). Of course you can call a page action and the
entity instance should be available in that page action if its identifier is
set as a page parameter.
No idea why it doesn't work in that particul
I'm confused. Doesn't seam gen create edit pages with a wire() page action
which calls getInstance()?

I don't know what you want to do, because obviously printing something on the
console is not a regular case. You can call getInstance() _after_ the @Create

That is currently not doable with the entity framework in Seam and something I
recently discussed with Gavin. You can't call getInstance() in either a page
action or an @Create method, the identifier binding will happen afterwards (if
it's a page parameter).
Really, there is no obvious solution
Here comes some code... I hope somebody can give me a hint
Here is the entity:

Why not? I think you should be able to.
It'd be a good idea to post some code.
