Issue

  • Opening different pages and menus on DXP 7.2 and above could result in an empty page showing the ${processor.processMax()} error message
  • The solution only applies if you use the module.framework.properties.org.osgi.framework.bootdelegation property in your portal-ext.properties, and see the below exception in your logs
Caused by: javax.servlet.ServletException: java.lang.NoClassDefFoundError: com.liferay.expando.kernel.model.ExpandoBridge cannot be found by com.liferay.layout.page.template.api[version]

Environment

  • Liferay 7.2+

Resolution

  • There is an added value of the module.framework.properties.org.osgi.framework.bootdelegation​property for DXP 7.2 which is the com.liferay.expando.kernel.model class
  • Add the class as a value of the property, save it, and restart your portal
