Bug 36155 Workbench Help set on wrong Composite
In BuildPathsPropertyPage and SourceAttachmentPropertyPage the Workbench Help is set on the parent Composite passed to createContents(Composite parent) rather than on the control that is returned from getControl(). As a result the Help for the preference page cannot be used in when performHelp() is called. In JavadocConfigurationPropertyPage and JavaElementInfoPage the Workbench Help is set on a different composite, but still not the control that is returned from getControl().
