merging a list of booleans

Hello

I want to check each list in a data tree for a boolean false value. I then want to replace the entire list with a single true/false. My problem is that each branch is of arbitrary length. Is there a way around this without resorting to scripting?

Look at this link.

https://api.ning.com/files/sADsGzPuhoDnqghrBp7Z*18V-OSLH5RiQSEf*wEF7w-AB*wVrvOyrx4337STlXdWvw4LGsLtCJpDE1*o3yUlKhPKkSol4JYT/Grasshopper.jpg__It was for a different but similar problem and I think contains what you need in it. It depends a bit on how you need to read the False values in a list, if there is two and you need to know that, it will be harder to do, but if it doesn't matter how many False values can be in the list you just need it to show False as a conclusion for the whole list just because it contains whatever number of False Values then the above link should work for you.

If it doesn't work I will take another look.

That other link didn't want to work, open the last image on the discussion page.

Frans,

One approach would be to feed the boolean data into Mass Addition component.

Since True = 1 and False = 0 you can compare the boolean total for each branch with the total number of items in the branch.

If the boolean total is less than the item total, a false value is present.
