I'm posting this on behalf of the <a href="http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla:en-US:official&q=eclipse+%22NewElementWizard.performFinish%22+InvocationTargetException&start=30&sa=N" rel="nofollow noreferrer">30 or so projects</a> that seem to be suffering from this problem without any resolution. Basically the problem boils down to, a subclass of org.eclipse.jdt.internal.ui.wizards.NewElementWizard (which is the "Wizard" that controls the creation of new JDT elements like projects, packages, classes, etc -- this problem seems to happen no matter what reason you're subclassing for) overloads performFinish() and calls super.performFinish() as part of that call. So far so good, but for some reason if this happens on an empty workspace (which is often the case for new projects), the super.performFinish() call fails with an exception similar to the following: <pre><code>java.lang.reflect.InvocationTargetException at org.eclipse.jface.operation.ModalContext.run(ModalContext.java:350) at org.eclipse.jface.wizard.WizardDialog.run(WizardDialog.java:851) at org.eclipse.jdt.internal.ui.wizards.NewElementWizard.performFinish(NewElementWizard.java:133) at com.canoo.wizard.newproject.NewULCProjectWizard.performFinish(NewULCProjectWizard.java:118) at org.eclipse.jface.wizard.WizardDialog.finishPressed(WizardDialog.java:680) at org.eclipse.jface.wizard.WizardDialog.buttonPressed(WizardDialog.java:355) at org.eclipse.jface.dialogs.Dialog$3.widgetSelected(Dialog.java:660) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:90) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) </code></pre> or something similar to that -- the error is strikingly similar across dozens of different projects that I've found in the process of Google'ing about for this error, whether the subclass of the NewItemWizard happens to be a Project Wizard, a Class Wizard, whatever. Some of the people reporting this problem later post that it was caused by a "version mismatch" but, maddeningly, they never give any details as to what versions were mistmatching with what -- and I've tried my code on Linux, Windows, and OS X so I doubt it's some very version-or-platform-specific nuance. Lastly, there does not seem to be anything in the Eclipse bugzilla even tangentially related to this problem. Has anyone run into this before, since it seems so ubiquitous? Any help would be greatly appreciated!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
