I have a solution that I recently migrated from Firebird to Sybase. sometime after the migration (but not immediately after) I have a form that will not display at runtime. If i select it from the Window menu, it will not display (only displays the form displayed before selection. If I switch to design mode I will see the form, but when I switch back to runtime the form still is displayed in design mode. Servoy Developer Version R2 2.1beta5-build 303 Java version 1.4.2\_04-b05 (Windows 2000) ---

Try to upgrade to Servoy 2.1 rc2 and check again if problem occurs, if so check .log file to see if any error is listed. ---

Have you tried to hang this script at the Onload property of the first form? and not at as OPenSolution-method? at an open-solution-method you can not call databases, because they are simply not there! You only can set element things. What happens, if you completly ignore the method? does the solution than works right? Hope this helps ---

The openSolution method is called onShow of the first form in the solution. If I remove the method from the onShow event the first error does not happen. The openSolution method itself is not the problem, I think. If I open the solution without the method the log file is > Starting Servoy from D:\Program Files\ServoyServoy R2 2.1rc2 build-306 on Windows 2000 using Java 1.4.2\_04Loading servoy.properties from C:\Documents and Settings\Administrator\servoy.propertiesLoading - Done and then I move to the “user” form manually (which is referenced in the openSolution method) there is no change on the screen and the contents of the log.txt file is: > Starting Servoy from D:\Program Files\ServoyServoy R2 2.1rc2 build-306 on Windows 2000 using Java 1.4.2\_04Loading servoy.properties from C:\Documents and Settings\Administrator\servoy.propertiesLoading - Donejava.lang.NullPointerExceptionjava.lang.NullPointerException > at com.servoy.j2db.dataprocessing.aa.getValue(Unknown Source) > at com.servoy.j2db.dataui.DataField.setValue(Unknown Source) > at com.servoy.j2db.dataprocessing.an.a(Unknown Source) > at com.servoy.j2db.dataprocessing.an.setRecord(Unknown Source) > at com.servoy.j2db.dataprocessing.d.a(Unknown Source) > at com.servoy.j2db.dataui.m.getListCellRendererComponent(Unknown Source) > at javax.swing.JList.updateFixedCellSize(Unknown Source) > at javax.swing.JList.setCellRenderer(Unknown Source) > at com.servoy.j2db.FormPanel.setView(Unknown Source) > at com.servoy.j2db.FormManager.a(Unknown Source) > at com.servoy.j2db.FormManager.do(Unknown Source) > at com.servoy.j2db.develop.ab.do(Unknown Source) > at com.servoy.j2db.FormManager$2.run(Unknown Source) > at java.awt.event.InvocationEvent.dispatch(Unknown Source) > at java.awt.EventQueue.dispatchEvent(Unknown Source) > at java.awt.EventDispatchThread.pumpOneEventForHierarchy(Unknown Source) > at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) > at java.awt.EventDispatchThread.pumpEvents(Unknown Source) > at java.awt.EventDispatchThread.pumpEvents(Unknown Source) > at java.awt.EventDispatchThread.run(Unknown Source)) ---
