Hello ULC-Folks, after our ULC upgrade from 6.1.1 to 2008u3 we have a crash due to the usage of a validating table cell editor.
java.lang.RuntimeException: Unable to create new instance of cell component at com.ulcjava.base.server.CellComponentTemplateStorage.createTemplate(CellComponentTemplateStorage.java:26) at com.ulcjava.base.server.CellComponentTemplateStorage.getTemplate(CellComponentTemplateStorage.java:38) at com.ulcjava.base.application.ULCTable.a(ULCTable.java:380) at com.ulcjava.base.application.ULCTable.requestCellEditorComponents(ULCTable.java:495) at com.ulcjava.base.application.ULCTable$ULCTableDispatcher.requestCellEditorComponents(ULCTable.java:7) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.ulcjava.base.shared.internal.ReflectionUtilities.invokeMethod(ReflectionUtilities.java:51) at com.ulcjava.base.application.ULCProxy.processInvokeULC(ULCProxy.java:67) at com.ulcjava.base.application.ULCProxy.handleRequest(ULCProxy.java:401) at com.ulcjava.base.server.ULCSession.processRequest(ULCSession.java:234) at com.ulcjava.base.server.ULCSession.processRequests(ULCSession.java:387) at com.ulcjava.base.development.DevelopmentContainerAdapter.processRequests(DevelopmentContainerAdapter.java:4) at com.ulcjava.base.development.DevelopmentConnector.sendRequests(DevelopmentConnector.java:31) at com.ulcjava.base.client.UISession$k_.run(UISession$k_.java:66) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.InstantiationException: com.canoo.ulc.community.validation.ULCValidationTextField at java.lang.Class.newInstance0(Class.java:340) at java.lang.Class.newInstance(Class.java:308) at com.ulcjava.base.server.CellComponentTemplateStorage.createTemplate(CellComponentTemplateStorage.java:27) ... 17 more I investigated as far as the non available source code permits. My resuluts/guess is the following: The problem is caused by our ValidatingCellEditor (implements ITableCellEditor) which uses a ULCValidationTextField as editor component. This class does not posess a parameterless constructor, but the CellComponentTemplateStorage appears to try to create a new instance (beside the already existing one, which is always returned by getTableCellEditorComponent). This fails due to the missing constructor -> crash. How can i circumvent this problem?
