I don't really understand what you are going on about here but why can't you
simply exclude null values in the popup and they won't get selected and thus
create your problem.

Hello -
I have a pattern where I have a list of lists. These are called metrics and
their possible values metricValues.
I want to assign a value for each metric to a project. This means that I
have to dynamically show the metric list and then allow the user to select
one value for each of the metric's list of values. I had originally created
a many-to-many relationship to the metricsValue since that would be
theoretically enough as I could always get the selected values metric. My
problem occurs when the user selects a null value in the popup. Now I don't
have a way to find its parent metric anymore.
How do others handle this list of list with a relationship design problem?
Thanks again,
James Cicenia
