Hi Tim,

I have found 2 problems in your project.

1) minor mistake.
    table Crheaders, field NumberU have formula text "=upper()"
                                                    ^^^

    operator = must not present here.
    you can easy see this in viSQL or in VAPP.
    such mistake means that method will not work.


2) now serious mistake. You see problem with insert after delete BECAUSE
    
    in table onlines you have BaseObject method Numberu
    created in table BEFORE the field it refers the 'Number'.

    this is mistake similar to programming languages
    you refer to variable before it is created.

    as far I see Valentina 2.0 will be able work
    correctly in such situation,


It is hard to see creation order, I should say.
ViSQL sort fields in alphabetical order
VAPP show fields in methods in different TABs of dialog. Hmm.

I think you can see this only in XML dump.

    Jochen, I think Valentina Studio must allow see fields
    a) in alphabetical order
    b) in order of creation.
    c) later we want add custom order.

Tim, are you in the mode development?
If yes, then change order of creation of fields in your code.
