Error on clicking on Booking in administrator's menu

[gassma...@gmail.com]

Hello, first let me say thanks for fixing the PayPal support :) Anyway I noticed a problem with Version 11.3. When I click on the Bookings menu item in the administrator's menu, I get an error. It's a java null pointer exception, here's the error log:     **RedScreen** could not create controller via reflection. classname:org.olat.resource.accesscontrol.ui.OrdersAdminController ::_::    olatMenuTree    org.olat.core.gui.components.tree.MenuTree    n/a    org.olat.core.gui.components.tree.TreeEvent    ctncl    TreeEvent:{cmd:ctncl, nodeid:95372110015222}    org.olat.admin.SystemAdminMainController    org.olat.core.commons.fullWebApp.BaseFullWebappController    ::_:: Cause     >>>stack of 1.cause::org.olat.core.logging.AssertException: could not create controller via reflection. classname:org.olat.resource.accesscontrol.ui.OrdersAdminController -> at org.olat.core.gui.control.creator.AutoCreator.createController(AutoCreator.java:92) at org.olat.core.extensions.action.GenericActionExtension.createController(GenericActionExtension.java:122) at org.olat.core.gui.control.generic.layout.GenericMainController.createController(GenericMainController.java:378) at org.olat.core.gui.control.generic.layout.GenericMainController.getContentCtr(GenericMainController.java:389) at org.olat.core.gui.control.generic.layout.GenericMainController.event(GenericMainController.java:325) at org.olat.core.gui.control.DefaultController.dispatchEvent(DefaultController.java:202) at org.olat.core.gui.components.AbstractComponent$1.run(AbstractComponent.java:240) at org.olat.core.logging.activity.ThreadLocalUserActivityLoggerInstaller.runWithUserActivityLogger(ThreadLocalUserActivityLoggerInstaller.java:108) at org.olat.core.gui.components.AbstractComponent.fireEvent(AbstractComponent.java:238) at org.olat.core.gui.components.tree.MenuTree.handleClick(MenuTree.java:300) at org.olat.core.gui.components.tree.MenuTree.doDispatchRequest(MenuTree.java:199) >>>stack of 2.cause::java.lang.reflect.InvocationTargetException: null -> at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.olat.core.gui.control.creator.AutoCreator.createController(AutoCreator.java:72) at org.olat.core.extensions.action.GenericActionExtension.createController(GenericActionExtension.java:122) at org.olat.core.gui.control.generic.layout.GenericMainController.createController(GenericMainController.java:378) at org.olat.core.gui.control.generic.layout.GenericMainController.getContentCtr(GenericMainController.java:389) at org.olat.core.gui.control.generic.layout.GenericMainController.event(GenericMainController.java:325) at org.olat.core.gui.control.DefaultController.dispatchEvent(DefaultController.java:202) at org.olat.core.gui.components.AbstractComponent$1.run(AbstractComponent.java:240) >>>stack of 3.cause::java.lang.NullPointerException: null -> at org.olat.resource.accesscontrol.manager.ACFrontendManager.findOrderItems(ACFrontendManager.java:650) at org.olat.resource.accesscontrol.ui.OrdersDataSource.getRows(OrdersDataSource.java:112) at org.olat.core.gui.components.form.flexible.impl.elements.table.DefaultFlexiTableDataSourceModel.loadDatas(DefaultFlexiTableDataSourceModel.java:207) at org.olat.core.gui.components.form.flexible.impl.elements.table.DefaultFlexiTableDataSourceModel.load(DefaultFlexiTableDataSourceModel.java:176) at org.olat.core.gui.components.form.flexible.impl.elements.table.FlexiTableElementImpl.(FlexiTableElementImpl.java:180) at org.olat.core.gui.components.form.flexible.FormUIFactory.addTableElement(FormUIFactory.java:927) at org.olat.resource.accesscontrol.ui.OrdersAdminController.initForm(OrdersAdminController.java:174) at org.olat.core.gui.components.form.flexible.impl.FormBasicController.initForm(FormBasicController.java:280) at org.olat.resource.accesscontrol.ui.OrdersAdminController.(OrdersAdminController.java:125) at org.olat.resource.accesscontrol.ui.OrdersAdminController.(OrdersAdminController.java:112) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) empty There's also a second error which seems to have the same cause.

Hi

Which version of OpenOLAT are you using? And which database? I cannot currently reproduce your problem.

Best regards

We're using OpenOLAT 11.3.0 with a MySQL database.

Just to add, we experienced the same error with Version 11.2.0 of OpenOLAT. We thought it might be a problem because of the updated PayPal implemetation. But since we don't really use that function, we didn't report it.

Hi

The issue is fixed in 11.3.1 which is planned for this week.
