Hey everyone.

Beginner question, but I couldnt find an answer in the docs.

Lets say I have a table component filled with test data. Next I create a label component and add a custom property to it, binding it to the data of the table component.

Does this duplicate the data from the table, or is the binding simple a pointer to the dataset in the table?

If its relevant, Im using Ignition 7.9.9.

Thanks for any help

For the simplest data types, like booleans and numbers, you get a copy. For objects, you generally get a reference to the same data. This is the reason that Datasets are supposed to be treated as immutable, even through there are ways to modify most instances.
