global variables

Hi,

Is it possible to set, with a new node, a global variable?

Thanks

No, you can only set variables that are visible to all downstream nodes.

Hi,

Is is possible that during NodeModel#execute, i overwrite the value of a workflow variable.

Cheers,

Ken

You can "push" a new variable with the same name and a different value inside execute. The new value will be visible to all downstream nodes.
