Do you have a sample model that demonstrates this exception? It's
really hard to diagnose an error report like this otherwise.

A before-and-after model along with the list of the changes that were
made in the UI would be very useful in this case. Do you use
prototypes? Project Wonder prototypes? That would be the most
likely explanation for external type columns being removed (i.e. if
your prototype defines them and EOM), if I had to take a guess. But
I would need to see the model to know what's actually going on.

Well, of course, the answer is that you don't have to ... But give us
a little bit of a break here -- EntityModeler is just a few months
old, EOModeler had 10 years, and there's near zero documentation on
the internals.

from decompiled EOF:
if(name.equals("NSCalendarDate"))
return "com.webobjects.foundation.NSTimestamp";
NSCalendarDate and NSTimestamp are equivalent.
What you're seeing on the data type side is that in EOModeler doesn't
present to you the full list of data types (see file:///Developer/ADC%

4WorkingWithAttributes/chapter_4_section_3.html#//apple_ref/doc/uid/
TP30001018-CH204-BABFGECE ). "Date (Object)" is the name we give to
NSTimestamp/NSCalendarDate with no value type:

> What am I doing wrong? Or is there a problem with EntityModeler?
EM generating a model that EOM can't reopen is definitely a bug. We
should never do that. I would need more details to know what is
actually going on, though.
