I think you may have imagined this. If there ever was such a list, there's no 
way it would be current and maintained.

Just to echo Chuck: this is going to be a big problem.

Are you thinking of this?

“the database has exposed primary and foreign keys that are mostly strings and 
char. The application is a mess”

You repeat yourself.  :-)

Exposed PK values are generally a bad idea, but EOF is OK with them.  Exposed 
FK values cause serious problems with EOF maintaining graph consistency.  Fix 
that and setting relationships should just work again.

Hi Markus,

I don’t know of any property.

Because they are exposed they are treated as attributes.

Because they are relationships they are treated as foreign keys.

So you really have to set both… I don’t see a way around it. If you don’t there 
is a race condition for who wins and you’ll never win.

Would be better to make the attribute non-exposed and then create a cover read 
only (perhaps derived) property on that attribute to “expose” it for the legacy 
app. I mean… for whatever reason they want those integer values exposed so this 
is your best bet.

List of all Properties? Legacy EOModel with exposed keys.....

2018-09-17 Thread Markus Ruggiero 
I thought I have seen a list of the properties that Wonder supports but I 
cannot find it anymore. I have no idea where I saw this list. Could have been 
here or somewhere in the docs or the Wonder Source. But it is late and I am 
tired and I have been searching for it invain. Anyone to help me?

Background:
I am struggling with a legacy legacy legacy pure old time WebObjects 
application. No Wonder, no Eclipse, but WindowsXP with ProjectBuilder (sourcode 
goes back to 1998/1999!!!). And the database has exposed primary and foreign 
keys that are mostly strings and char. The application is a mess and I am 
trying to bring it into Eclipse and use Wonder. Unfortunately 
WOToOneRelationship does not connect objects. Manually using 
addObjectToBoth does not connect objects either (debugger shows that the
