I was modifying the dita.css styles (removed the import statements and defined new styles in one css file) for tables and came across this bug(?) with the content property. I wanted to show empty table cells with nothing in them. The default is with the word entry on a grey background. So within the tbody I wrote the following style tbody row > entry { display: table-cell; padding: 5px; border: 1px solid black; content: ""; } and the cell now appears empty but when done to an entry as a descendant of thead thead row > entry { display: table-cell; padding: 5px; background-color: white; color: black; font-size: 12pt; font-weight: bold; border: 1px solid black; text-align: center; vertical-align: middle; content: ""; } The following happens in Oxygen 11: The entire page in the author view is blank. The following happens under Oxygen 10.2 and 10.3 The following error message appears and a blank page in the author view [ AWT-EventQueue-0 ] - java.lang.ArrayIndexOutOfBoundsException: -1 java.lang.ArrayIndexOutOfBoundsException: -1 at ro.sync.ecss.A.g.A(Unknown Source) at ro.sync.ecss.A.m.E(Unknown Source) at ro.sync.ecss.A.G.A(Unknown Source) at ro.sync.ecss.A.G.A(Unknown Source) at ro.sync.ecss.A.C.A(Unknown Source) at ro.sync.ecss.A.C.A(Unknown Source) at ro.sync.ecss.A.C.A(Unknown Source) at ro.sync.ecss.A.C.A(Unknown Source) at ro.sync.ecss.A.C.A(Unknown Source) at ro.sync.ecss.A.f.A(Unknown Source) at ro.sync.ecss.component.J.è(Unknown Source) at ro.sync.ecss.component.J.ѕ(Unknown Source) at ro.sync.ecss.component.J.L(Unknown Source) at ro.sync.ecss.component.J.K(Unknown Source) at ro.sync.exml.editor.xmleditor.pageauthor.E$5.run(Unknown Source) at ro.sync.ui.g$1.run(Unknown Source) at ro.sync.ui.g.A(Unknown Source) at ro.sync.exml.editor.xmleditor.pageauthor.E.L(Unknown Source) at ro.sync.exml.editor.BA.K(Unknown Source) at ro.sync.exml.editor.AB.readDocument(Unknown Source) at ro.sync.exml.editor.R.K.readDocument(Unknown Source) at ro.sync.exml.editor.xmleditor.g.readDocument(Unknown Source) at ro.sync.exml.editor.PA.A(Unknown Source) at ro.sync.exml.editor.PA.A(Unknown Source) at ro.sync.exml.editor.AB.K(Unknown Source) at ro.sync.exml.editor.xmleditor.g.K(Unknown Source) at ro.sync.exml.editor.AB.open(Unknown Source) at ro.sync.exml.editor.xmleditor.pageauthor.E.Ϡ(Unknown Source) at ro.sync.exml.editor.BA.ξ(Unknown Source) at ro.sync.ecss.component.D.D.B.actionPerformed(Unknown Source) at ro.sync.exml.D.C$_A.actionPerformed(Unknown Source) at ro.sync.ui.HA.actionPerformed(Unknown Source) at ro.sync.ui.MA$4.actionPerformed(Unknown Source) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1995) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2318) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at com.jidesoft.plaf.basic.BasicJideSplitButtonUI$MouseInputHandler.A(Unknown Source) at com.jidesoft.plaf.basic.BasicJideSplitButtonUI$MouseInputHandler.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Component.java:6134) at javax.swing.JComponent.processMouseEvent(JComponent.java:3265) at java.awt.Component.processEvent(Component.java:5899) at java.awt.Container.processEvent(Container.java:2023) at java.awt.Component.dispatchEventImpl(Component.java:4501) at java.awt.Container.dispatchEventImpl(Container.java:2081) at java.awt.Component.dispatchEvent(Component.java:4331) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4301) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3965) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3895) at java.awt.Container.dispatchEventImpl(Container.java:2067) at java.awt.Window.dispatchEventImpl(Window.java:2458) at java.awt.Component.dispatchEvent(Component.java:4331) at java.awt.EventQueue.dispatchEvent(EventQueue.java:599) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) I found a solution to the problem but am concerned about the different behaviour due to context of the entry element. content: “ “; just add a space when a descendant of thead Marijan (Mario) Madunic Publishing Specialist New Flyer Industries mario_madunic@newflyer.com -------------------------------------------------------------------- Please consider the environment before printing this e-mail.
