saguaros today v1.03 of T4 Page builder has been released, but at installing the package (t4-pagebuilder-pkg_1.0.3.zip) on a JL4.0 beta 4 site i get the error "Argument 2 passed to pkg_t4_page_builderInstallerScript::preflight() must be an instance of JAdapterInstance, instance of Joomla\CMS\Installer\Adapter\PackageAdapter given,"
Installing all components seperately i see no error....
When i try to create a menu item from the T4 page builder dashboard no error was given, but when i want to open the page just added to the mainmenu i get another error "0
Class 'Factory' not found"..... (location /volume1/web/betatest/components/com_t4pagebuilder/views/page/view.html.php (150) }
Can you follow up on these questions ?
