Hi Greg,
That does make sense. The relationship between the two data groups is the featureID which maps onto the refs data element.
When i add that filter, the features do get filtered, but only by removing the features that are not referenced by any solution.
for example if i had 10 features and 2 solutions, solution 1 references the even features (2, 4, 6, 8, 10) and solution 2 references the features whose id is divisible by 3 (3, 6, 9) then the form when used looks like this:
solution 1
feature 2,
feature 3,
feature 4,
feature 6,
feature 8,
feature 9,
feature 10
solution 2
feature 2,
feature 3,
feature 4,
feature 6,
feature 8,
feature 9,
feature 10
where it should look like this:
Solution 1
feature 2,
feature 4,
feature 6,
feature 8,
feature 10
solution 2
feature 3,
feature 6,
feature 9
the filter doesnt seem to filter the feature list by solution, but by solutions as a whole.
cheers for your help in this
