Good morning!

What do these arrows mean?

I thought it meant that the flow allowed will be forward between those screens, but not...

I need to implement 2 conditions:

  1. avoid the user to go back to a previous screen;
  2. avoid the user to enter in a screen (PreInscricao in this example) without having entered in the first screen (RGPD in this example).

Is this possible in Outsystems?

Thanks!

Hi,
1 - You can achieve this using javascript

 Disable Browser Back Button

      $(document).ready(function() {

         function disablePrev() { window.history.forward() }

         window.onload = disablePrev();

         window.onpageshow = function(evt) { if (evt.persisted) disableBack() }

      });

   


2- You can achieve this by assigning specific role to the user for that particular page

Thanks.

Hi Sidhharth,

Hi Diogo,


These arrows mean that there is a link on the source screen that goes to the target screen.

Regarding how to prevent it, there are a few ways:

  1. Upon going through the RGPD screen, you grant the user a given role. And only with that role you can access to the other screens;
  2. Upon going through the RGPD screen, you save on the database that that user is ok to go. On every screen, you check the database and only get the rest of the data after confirming that the user has gone through it, otherwise you send him to an Invalid Permissions screen or something like that.


Kind Regards,
João

Don't put to much value in the UI Flow canvas.

Regarding your questions:

1. See https://www.outsystems.com/forums/discussion/68440/disable-browser-back-button/

2. Yes put validation in before user can navigate.

Regards,

Daniel
