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.
