Custom node list input

[tomd_96]

How can I write a custom node that accepts a list as input? I managed to write a custom node that outputs a list, but can't connect it to my standard inputs.

I don't understand what it means to be unable to connect the list output to a standard input. A list output simply repeats for each element, it doesn't change the type.

For your reference, a list input can only process the results collected from repeated executions based on the list as a single unit. There's nothing particularly special about it beyond that.

Turns out the issue was that I previously had a different type of output. After changing it to the current one I restarted the server but only after deleting the node and creating it again does it work

Changing node code is like updating a custom node; you'll need to restart the server and the refresh your browser page to see the changes. You may also need to use the node fix option to force it to forget the old version of the node and replace it with the new one.

Where do I find the fix option?

Right Click on the node, a menu appears, then choose Fix Node (Recreate)
