I have a component with a datagrid, within this component I created an array variable, and put the data from the datagrid as this variable. I’m trying to change this variable outside the component in a workflow page, but I’m unsuccessful ---

Hey @enzocarmo The Expose outside option is for reading the variable. To modify your variable you’d need to create a component workflow that does this, with the appropriate parameters. And expose that component workflow outside. Then, you can execute it from your page workflow with an Execute component workflow 🙂
