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
