[jbosstools-issues] [JBoss JIRA] Updated: (JBIDE-3144) EL resolution causes VPE to loose its synchronization

EL resolution causes VPE to loose its synchronization ----------------------------------------------------- Key: JBIDE-3144 URL: https://jira.jboss.org/jira/browse/JBIDE-3144 Project: Tools (JBoss Tools) Issue Type: Bug Components: Visual Page Editor core Affects Versions: 3.0.0.beta1 Reporter: Max Rydahl Andersen Assignee: Maxim Areshkau Priority: Blocker Fix For: 3.0.0.cr1 Attachments: An unexpected exception was thrown.log, Unhandled event loop exception1.log (I've only tried this with the Seam generated projects, but I don't think it is specific to it) EXECUTE: Create a Seam web project EXECUTE: Change template="layout/template.xhtml" to template="#{request.contextPath}/layout/template.xhtml"> EXECUTE: Setup request.contextPath = ./ in page design options EXECUTE: Refresh editor ASSERT: Editing continues to work ACTUAL: Edits is not visible in VPE and edits through VPE result in edits in the top line of the file instead of inside the file. This is marked blocker since EL resolution is rather pointless if it breaks up the editor ;( Sometime I got this exception: org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:3777) at org.eclipse.swt.SWT.error(SWT.java:3695) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:136) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3800) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3425) 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.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) 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(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) 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) Caused by: java.lang.NullPointerException at org.jboss.tools.vpe.editor.VpeVisualDomBuilder.cleanHead(VpeVisualDomBuilder.java:1507) at org.jboss.tools.vpe.editor.VpeVisualDomBuilder.rebuildDom(VpeVisualDomBuilder.java:241) at org.jboss.tools.vpe.editor.VpeVisualDomBuilder.updateNode(VpeVisualDomBuilder.java:944) at org.jboss.tools.vpe.editor.VpeController.notifyChangedInUiThread(VpeController.java:670) at org.jboss.tools.vpe.editor.VpeController$1.runInUIThread(VpeController.java:525) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:94) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:133) ... 22 more
