When creating a project from the jboss-javaee6-webapp6 project example (Maven Archetype) the name property is displayed twice in the properties table.
It's set the first time when calling setArchetype(archetype) in ArchetypeExamplesWizardPage.createControl(), then a second time, when loadArchetypeDescriptor() is called by MavenProjectWizardArchetypeParametersPage.setVisible()

Setting archetypeChanged = false; in ArchetypeExamplesWizardPage.createControl() seemingly fixes the issue, but I'm concerned as loadArchetypeDescriptor() doesn't get called that way. Will try overriding setArchetype() instead.
