    1. The replacement key is used to replace the surrogate key with a natural key in GUI. No such a replacement is needed if no surrogate key is involved.
    2. A table can can several unique keys, but only one of them can be primary.

    Hi Martin,

    1. So if the primary key was Not surrogate key, then in this case, we can have to leave replacement key as empty then use resolveReference method?
     
    2. what's the difference between primary key and an index with duplicate No?

    No, I wasn't talking about that at all.
    If your table has SurrogateKey as the primary index, you should always set the replacement key.

    Hi Martin,

    you mean i use this method, when I leave the replacement key property on the table as empty?

    If you don't want to wait hours for an answer, simply try it. You'll see that resolveReference() isn't needed for the lookup.
     
    It's not used very often; it's for some special cases when you don't use a key in the replacement group.

    Ok, if I will go with the lookup reference example, they also use resolveReference method with it, do i need it as well? And what does this resolveReference do in the first place?

    I'm not sure, but I always use the method specific to reference groups: lookupReference().

    Hi Martin,

    one of your examples uses "formReferenceControl" with "lookupReference" method and "resolveReference" method, like this:



    And the other one uses "formReferenceGroupControl" with "lookup" method

     
    what's the difference between the two??

    Yes, it's possible.
     
    You can find several examples in the existing codebase, e.g. in BusinessProcessGenericTaskEditorDialog_PersonnelManagement_Extension or CaseDetailEventHandler class.
