Breaking auto realding feature with embeded classes
So one of my favourite features is the fact that once I change some piece of
the code, I dont have to restart the application, all I have to do is let
auto reloading work its magic. Sadly I have found a way to break that
feature :(
I have a page that has a bunch of block, so in order to keep things simple I
am using the embeded Enum class to map which block should be displayed.
However once I change something I get the following exception
com.bomahabo.flow.tapestry.pages.Scenes$ShotView cannot be cast to
com.bomahabo.flow.tapestry.pages.Scenes$ShotView
I take it that I can move the embeded class outside and that it wont cause
the problems but since this class is only used in here I would like to keep
it there. Any suggestion about this? Also if someone from dev team is
reading this, are you aware of this problem.
Cheers

Alas no. All classes inside those packages (and sub packages) are
transformed (re-loaded) by T5. I either stick it in the "services"
package or create a separate package called "util" or "entity".
com.myapp.components
com.myapp.pages
com.myapp.services <-- here
com.myapp.entities <-- or here
com.myapp.util <-- or here

I see, well that makes sense. Can I place that class then inside a components
page, or better yet components subpackage?

Correct, the Enum class has to reside outside of the special packages.
Otherwise, as observed, once the Enum class is reloaded, it's a
totally different class, incompatible with any previous references. T5
cannot replace these references as a) they're not injected b) may be
used in non-T5 classes.

This is actually expected. Anything that isn't a page (including nested
classes, unless they're used only inside the page and instances of it not
passed to other classes) shouldn't be inside the pages package. Make your
enum class a top-level one and put it outside the Tapestry controlled
packages.
Could you please provide the complete stack trace?
