Creating a unique collection in flow
this is a very short post, that shows one small thing that can be very useful - creating a collection of unique elements in visual workflow
there are now quite a few operators on collections in flow, but none of them are ‘remove duplicates’ or ‘add if new’ or anything like that.
i found a way to do this that requires only a single assignment element - no loops or decisions required
step 1 : remove all instances of (X)
step 2: add (X)
this ensures that your collection will only contain one copy of the element.
maybe there is an easier way, but this works!
