Hi guys,

Is it possible to put dynamic content in a node field without having a function node as an input?

Eg. I have a `flow.chartTempFname` variable. I would like to insert it in the `Filename` field. Do I have to use a function node as an input or there's an existing syntax such as `$$flow("chartTempFname")` to get the context variable?

Thanks

You set it either in the node, or by passing in `msg.filename`. You can use a Change node set `msg.filename` to whatever you want dynamically.

You cannot set it via context directly in the node.

Ok, I needed a confirmation that there's is no shortcut for my needs.

Thanks!

I just noticed in one of my nodes, I see a function in the `Value format` field.

Where can I get documentation about this feature?

Did you look at the ‘Help’ tab while the node is selected?
