Ignore nested families

I am using Data Shapes to have a user select element categories & then allow them to select a Workset. The end result is that Dynamo will get all elements of the chosen category/categories & set their workset to the User’s chosen one.

It all works great, except an error gets thrown when a family has a nested family inside of it. Dynamo tries to change its Workset independent of its parent family. Does anyone have a solution to this - perhaps to filter OUT nested families?

As you can see in the screenshot below - On the right, indices 308-310 are “Null” so the warning is thrown, however on the left those same indices did find elements (I checked & they are nested Pipe fittings nested inside a Fire Controls Assembly (Pipe Accessory).

I want to avoid these warnings/errors even though it does work because these are tools I am creating for our Teams - and as well probably all know the moment you give someone a new tool & it “breaks” they won’t want to use it again.

Thanks again for the assistance

Perhaps filter out selected elements where the parameter is marked as read only?

If all you want to do is avoid the warning, you can ususally avoid the pop-up or warning by using design script to wrap the function in another unnecessary function - say DSCore.List.FirstItem([yourfunction,null]);
