Created attachment 766803 [details] Server log. Description of problem: When using a site layout in which the portal page is placed inside a container, the site can be exported, but such export cannot be imported through the Site Redirects and Export/Import portlet again. Such layout generates a <page-body> element inside a <container> element in site's portal.xml file during export, which causes the following exception when the data is read during import: org.gatein.management.api.exceptions.OperationException: Exception reading data for import. ... Caused by: org.staxnav.StaxNavException: Unexpected element 'page-body' at [row,col]:[77,16] ... Steps to Reproduce: 1. Start the portal, sign in as root. 2. Go to Site > Manage Sites. 3. Choose e.g. the Classic portal and click Edit Layout. 4. Switch to the containers tab in the composer window and drag e.g. a two column layout to the page. 5. Place the Portal Page in the container and save. 6. Export the site, e.g. via GET /mop.zip?filter=site-type:!user,group. 7. Go to Group > Administration > Site Redirects and Export/Import > Import Site/Space. 8. Select your exported file and an arbitrary import strategy (e.g. Conserve) and click Import. Actual results: Import fails and an exception is visible in the server log. Expected results: The data is imported successfully.
