Title: Before row not fired for an empty DISPLAY ARRAY.
Post by: David Heydon on November 08, 2010, 01:36:05 PM

Comparing v2.11.02 to v2.21.10 we have noticed a change in behaviour with DISPLAY ARRAY when there are no rows to display. i.e:-

Code (genero) Select


    #assuming desc_arr is empty...
    DISPLAY ARRAY desc_arr TO smenu_arr.*
        BEFORE DISPLAY
            DISPLAY "Before Display"
        BEFORE ROW
            DISPLAY "Before Row"
        AFTER ROW
            DISPLAY "After Row"
        ON KEY (F10)
            EXIT DISPLAY
    END DISPLAY

With v2.11.02

Before Display
Before Row

With v2.21.10

Before Display

I don't see this mentioned in the 2.2x migration guide, so again I'm wondering if its a bug or a change in behaviour?

TIA.

David

Thanks Reuben.

I did actually try a forum search before posting but completely forgot about your issue tracker. Next time hopefully!

Cheers,

David
