docs: Add warning regarding execution order of item validation pipeline #294

Closed rennerocha closed 3 years ago

rennerocha commented 3 years ago

This happened in a real project. I enabled this pipeline, but added subsequent pipelines that changed the content of a valid item to an invalid content. This left me with an invalid item, but no validation error was raised. Adding this warning should prevent this kind of error (for the ones that read the docs :smile: ).
