Description:

As a Content Page Editor I'm not able to preview private site pages.

Steps to reproduce:

1) Create a private site page;

2) Go to page editor;

3) Click on "Preview" (eye icon).

Expected behavior: page content is displayed in the popup.

Actual result:  forbidden message is displayed in the popup:

 

Reason: the URL for preview page is generated incorrectly (has a wrong doAsUserId parameter, set to default user instead of current user).

Technical details:

previewPageURL is generated in

com.liferay.layout.content.page.editor.web.internal.display.context.ContentPageEditorDisplayContext :

As page is not template - 2nd parameter is true, and this method sets the default user to request:

This makes it not possible to preview pages, as default user does not have access to private pages.
