Unable to export site pages with circular references

    XMLWordPrintable

Description

    I have a site with different pages (content page) and every page has a footer with links to the relevant sections of the site.

    For example I have a "News and Events" page with two child page ("News" and "Events"). In the footer one of the links is "News and Events" pointing to "News and Events" page.

    So:

    • "news and events" page has a button to go to "News" page and a button to go to "Events" page
    • "News" page has it's own content but oalse the footer with the link to "News and Events". The same for "Events" page

     

    When I try to export the site this "circular reference" make the process loop and produce a stack overflow exception.

    For my tests this bug impacts every 7.4 CE and DXP. I've not tested 7.3 which also provide content pages.

     

    To replicate it:

    • start a fresh liferay bundle
    • go to guest site - Site Builder - Pages
    • create a first level "blank" page named "Test" and publish it with no content
    • create a "blank" page named "News and Events" child of "Test" and publish it with no content
    • create a "blank" page names "News", child of "News and Events"
    • add a "Button" fragment and in the link select "Page" and "News and Evets"
    • publish the "News" Page
    • edit "News and Events" page. Add a "Button" fragment and in the link select "Page" and "News"
    • publish "News ans Events" page
    • go to Publishing - Export and create an export process with only the "Test" page tree. You can deselect the contents

     

    Expected behaviour: export complete in few seconds

    Behavior obtained: process fail after a minute and the log il filled by stacktrace
