Hi List,
We debated this before and though some persons understood what I was saying, I
don't think there was any resolution, so this time I've got a little screen
shot to visually demonstrated the problem which is.
When one sets a collection member to any empty sting "" gambas beleives this
is the same as null and removes the item from the collection
ie mycollection!my_key = "Fred" is valid
mycollectioin!my_key = "" removes the key from the collection, instead of
setting its value to an empty string (ie string with no characters.
The implications of this in data saving as illustrated by the picture are as
follows
Here, the persons name/firstname/salutation were Smith/Stephanie/Steph, this
record was saved to the database. however I decided to remove salutation. As
gambas then sets this key to null - effectively removing it from the
collection, the field in the collection is not updated, and the original value
is left intact - ie 'steph' in the database field 'saluation', is not re-set
to an empty string.
I really wonder what can be done about this.
