Entity Developer

Hello,
I'm confused, the entity developer help has lots of references to column mappings, unique constraints etc. But i can't find any matching dialogues to actually allow me to setup these things. This is stopping me adding an association between two tables as i end up with an error
"Error: There is no unique constraint matching given keys for referenced table"
The help says there is a "Column Editor" which allows you to check a "Unique" box... this is supposedly visible from a "..." button in the column field of the property editor or the class editor. Nope not visible on my machine??!?!
Help!

Please specify what connection you want to implement one to one, one to many, etc.

Hi,
I think i tried all the various options but never got anything to do what i wanted.

I actually want a one-to-many. e.g. A "request" refers to/is for a "price list". So in database terms a "price list" has many "request"s.

Will try again later, but i trashed the model during my messing (in frustration).

Thanks

Hello,
I have got this working now... still can't find the options that the manual/help describes but in rebuilding the model it now works. Don't know what i did differently.
If i need them in future how do i find those options that are magic and hidden?
Thanks

You can specify a sign of uniqueness in PropertyEditor -> Unique = True
