I'm using a master detail display group to find the many objects of a single
item, but what I want to know is when adding and saving objects to a toMany
configuration, how can I do a check to be sure that a filePosition property
name is not being used in any other objects of that toMany configuration,
the master detail?
For example:
tbClient(toMany)>> <(toOne)tbClientDatas
EOModel Attributes:
FileName, FilePosition
The FilePosition is the property we are concerned with, for this we have a
WOPopUpButton populated with values: 01 logo, 01 Thumb1, 02 Thumb2, 03
Thumb3, 04 Thumb4, etc.
What I want to avoid is any one fileName containing the same filePosition,
so how do I do a check just on the master detail objects (tbClientDatas) of
an item (tbClient) to avoid this?
Thanks for any help offered
Jonathan
