Using Feedback_SetMessage in WebScreen preparation action, possible?

  
Hello everyone, I'm trying to display a warning when a user enters a webscreen, to do that I'm using the Feedback_SetMessage action from the widget library in the preparation action.
The problem is, so far nothing has been displayed, is there something that I missed or am I trying to do the impossible?
Thanks in advance.
Hi Paulo,

Welcome to our community! Does your page have the Feedback widget?
You need to insert a feedback widget (also from the widget library) in all your web screens. You can take a look into the StyleGuide templates for an example.

Ok, I've found the problem, I was using the action inside of a block instead of a screen, ooops, sorry.
