The No Operation unit doesn't execute any action, but it is used in order to simulate an operation chain. It is very useful when you need to exit and come back in a page to refresh the page or variable defined in the page.
An example could be :
- Entry unit in page
- A Link "Reset" from the Entry Unit that will reset the form.
- No Operation Unit outside the page
- Ok Link from the No Operation Unit with the Preserve Form flag unchecked
There's also a No Op content unit, that is a Content Unit, that will permit to model links inside the page. The Unit will be used inside a page. From this you will be able to add links that can have different kind of targets.
