[xwiki-users] serious xEclipse problems 1.2-rc-1

I have installed the xwiki-eclipse-rcp-win32-win32-x86-1.2-rc-1.zip simply copiing the content of the ZIP file into a directory and I started xEclipse. I created a new connection to http://localhost:8080/xwiki/xmlrpc/confluence with username Admin and the password respectively. After starting it gives a warning: A conflict occurred for CTRL+P:Binding(CTRL+P, ParameterizedCommand(Command(org.eclipse.ui.file.print,Print, Print, but this seems to be fairly harmless. When I tried to edit an object and to alter a "select list" value it only listed the current value and did not display the possible values. When I pressed 'Add' and then 'Cancel' on the pop-up window it gave another error: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List at org.xwiki.eclipse.ui.editors.propertyeditors.ListPropertyEditor$2.widgetSelected(Unknown Source) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:228) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2382) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2346) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2198) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:493) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:488) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.xwiki.eclipse.rcp.Application.start(Unknown Source) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) 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 org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) This is harmless, but this also happens when I try to add a value. This time it is not that harmless, because it prevents me to add a new value to the object. The format of the fields is nice and neat, but it has nothing to do with the ordering that I defined in the class the object belongs to. Then I double-click on a page to open it in wiki editing mode. It opens fine. Then I double click on the page again and I get the error: Problems occurred when invoking code from plug-in: "org.eclipse.jface". com.thoughtworks.xstream.io.StreamException: : Invalid byte 2 of

harmless, but I can not open the page again even if it was closed. I restart xeclipse and still: I can not open the page! This renders xeclipse UNUSABLE. Then I exit xeclipse and I go into the file system on my Windows XP and I delete the XEP file that seems to be the local copy of the page. First xEclipse tells me that there is some communication problem, and closes the connection. I reconnect and now I can open the page. Next time I try to connect to our external installation. This time the url is: https://myserver//xwiki/xmlrpc/confluence It opens fine and when I click on the '+' in front of the connection it shows the spaces. When I try to open a space it gives me an error: An internal error occurred during: "Fetching children of Main". org.eclipse.swt.SWTException: Invalid thread access at org.eclipse.swt.SWT.error(SWT.java:3777) at org.eclipse.swt.SWT.error(SWT.java:3695) at org.eclipse.swt.SWT.error(SWT.java:3666) at org.eclipse.swt.widgets.Display.error(Display.java:1180) at org.eclipse.swt.widgets.Display.checkDevice(Display.java:703) at org.eclipse.swt.widgets.Display.getActiveShell(Display.java:1349) at org.xwiki.eclipse.ui.adapters.XWikiEclipseSpaceSummaryAdapter.getChildren(Unknown Source) at org.xwiki.eclipse.ui.adapters.XWikiEclipseSpaceSummaryAdapter.fetchDeferredChildren(Unknown Source) at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:234) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
