I am cloning and modifying the model in the application constructor
to get a read-only model. This worked very well until I started to
use WO 5.4.2 prototypes. Once I started to use prototypes, the
prototypes' values are not being loaded in as the model is
constructed.
Looks like this process is pretty different in 5.4 ... So EOAttribute
has an _updateFromPrototype method you can call ... It appears that is
called on setPrototype, but I'm guessing it's not in the model when
that is called. It also appears that you can call
EOAdaptor.assignExternalInfoForEntireModel(model), which (among some
other things you'll have to verify as to whether or not they break
things) appears to be the only place that externally calls
_updateFromPrototype on all the attributes in the model. I'm not
exactly sure how the model loading process works now in 5.4 -- it's
something I'll have to dig around in to figure out better, but that
might at least get things working for you in the meantime.
