In the palette (for any diagram type) the icons have disappeared (well, i just see a generic file type icon for all of the items in the palette) and I just see a long description (i.e. in Use Case Diagram, I see "Actor.modeling_palette_item". Most importantly, I can't add any more elements to a diagram, but I can see previous diagrams in all their glory. This occurred after the update of the UML plugin from the released version to something newer (version 1.4.1). Somewhere in the middle I tried to install the Python plugin, upon restart I got a cryptic message, saw that the python plugin failed to install, uninstalled it. I haven't reinstalled 6.5, but I'm about to.
looks like a corrupted installation, did you try to uninstall/install uml again?
re-installing seemed to fix the problem. Not sure what created it.
do you mean uninstall-install only uml plugin? is it ok to close then? may be it was some problems with update center right after patch distribution started.
I have experienced the same problem after update from UML plugin 1.4.1 to 1.4.2. However, the generic file icons did not appear in the palette immediately after update but after some time. Not sure about the cause. When I - deactivated (not unstalled) the UML plugin - restarted Netbeans - activated the UML plugin - restarted Netbeans The UML icons in the palette were OK again.
thanks, deactivate-activate is a better workaround
When I click on one of the generic file icons which appear in the palette (in place of the UML icons), I get this exception: java.lang.NullPointerException at org.netbeans.modules.uml.drawingarea.actions.SceneAcceptAction.<init>(SceneAcceptAction.java:98) at org.netbeans.modules.uml.drawingarea.UMLDiagramTopComponent$6.propertyChange(UMLDiagramTopComponent.java:750) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:339) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:276) at org.netbeans.spi.palette.PaletteController$1.propertyChange(PaletteController.java:179) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:339) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:276) at org.netbeans.modules.palette.DefaultModel.setSelectedItem(DefaultModel.java:116) at org.netbeans.modules.palette.ui.PalettePanel.select(PalettePanel.java:276) at org.netbeans.modules.palette.ui.CategoryDescriptor$2.valueChanged(CategoryDescriptor.java:113) at javax.swing.JList.fireSelectionValueChanged(JList.java:1765) at javax.swing.JList$ListSelectionHandler.valueChanged(JList.java:1779) at javax.swing.DefaultListSelectionModel.fireValueChanged(DefaultListSelectionModel.java:167) at javax.swing.DefaultListSelectionModel.fireValueChanged(DefaultListSelectionModel.java:147) at javax.swing.DefaultListSelectionModel.fireValueChanged(DefaultListSelectionModel.java:194) at javax.swing.DefaultListSelectionModel.changeSelection(DefaultListSelectionModel.java:388) at javax.swing.DefaultListSelectionModel.changeSelection(DefaultListSelectionModel.java:398) at javax.swing.DefaultListSelectionModel.setSelectionInterval(DefaultListSelectionModel.java:442) at javax.swing.JList.setSelectionInterval(JList.java:2035) at javax.swing.plaf.basic.BasicListUI$Handler.adjustSelection(BasicListUI.java:2728) at javax.swing.plaf.basic.BasicListUI$Handler.mousePressed(BasicListUI.java:2684) at javax.swing.plaf.basic.BasicListUI$MouseInputHandler.mousePressed(BasicListUI.java:1502) at org.netbeans.modules.palette.ui.CategoryList$CategoryListUI$ListMouseInputHandler.mousePressed(CategoryList.java:453) at java.awt.AWTEventMulticaster.mousePressed(AWTEventMulticaster.java:263) at java.awt.AWTEventMulticaster.mousePressed(AWTEventMulticaster.java:262) at java.awt.AWTEventMulticaster.mousePressed(AWTEventMulticaster.java:262) at java.awt.Component.processMouseEvent(Component.java:6131) 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:3962) 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) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:599) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:104) 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)
May it be similar to http://www.netbeans.org/issues/show_bug.cgi?id=156718 ?
It seems a bit different from 156718. I have Netbeans 6.5 and UML 1.4.2. The UML projects seem OK only the icons from the palette are sometimes the UML icons and sometimes are the generic file icons. Sometimes only a restart of Netbeans makes the UML icons visible again. Deactivation and activation always help but in some time the problem is repeated.
