Pageextension Lay-out is locked

Posted on by 30

Hello guys. 
after deploying a page extension I can only make it work if I in the sandbox goes to Design, then I unlock the design - then my changes is accepted - but seems like the design keeps locking for me - can’t I from the extension say always unlocked? 
I‘ve checked, seems like there is no page extensions addons - Also tried delete all customization from the rolecenter

I have the same question (0)

    Hi, Sorry I didn't fully understand your question.
    But it looks like you didn't add the ApplicationArea Property to the new fields in your page extension.

    More details:

    Hello. It helps a bit, but the strange part is i modify some fields, set their "Visible" to =False, but that command is not always working. To make it work i need to press "Design" and "Unlock" and then it updates correctly - but next time the design is again locked...

    Perhaps it's better to change applicationarea to nothing on the fields parallel with setting Visible = False?

    Hi, Yes, if you just modify the Visible property of standard fields, you don't need to add ApplicationArea.

    Also, are you publishing to the Sandbox directly from VS Code? Will there be this problem if upload it in Extension Management?
