Hi community, I have been trying to solve this for a while whit no result and havent found nothing similar in the forum. What I want to do is group a list of elements, according to the value of one of his parameters.
I tried an aprox whit the node pickbyKey and using IDs as keys, this method worked but it doesnt admit duplicated values for the parameter. In this example I want to group the spaces as shown.
Total newbie attempting this but:
Would List.FilterByBoolMask work here? Plug the output of your < node into the mask input and you’ll get two lists - one where the condition is true and one where the condition is false.
Does not work for me 
it group the rooms but the criteria seems to be different… im gonna give it a try, gonna try to understand function.compose and will tell you. (Maybe units problem) Thanks! mmm, how would you do for X parameter?
several hours, against few minuts in this forum. Great! 
You are getting this result, because for some reason these two nodes are producing different values:
How could I make the function.compose node work whit the “GetParameter” node? Appearently it doesnt.
It is exactly the same thing:
It seems that not all parameters output a function whit “GetParameters” node. That was my problem. I think now i I got it =) Thanks all. Closed topic.
Thanks! Nice attempt haha
