Bug 37249 Export Javadoc does not give any error when the path to javadoc.exe is bogus
Version: 2.1.0 Build id: 200303272130 I had a bogus path to javadoc.exe in Preferences/Java/Javadoc. When I clicked Finish in the Export/Javadoc wizard, nothing happened. I gave up using the feature until today when I ran accross my bad Preference setting. Obviously, the wizard needed to give the user some kind of error message. (FYI, this happened when I upgraded my set up from Sun's 1.4.1_01 to 1.4.1_02.)
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/javadocexport/JavadocWizard.java
protected Set getSelectedProjects() {
		return fSelectedProjects;
	}
	protected void addSelectedProject(IJavaProject project) {
		fSelectedProjects.add(project);
	}
	protected void removeSelectedProject(IJavaProject project) {
		if (fSelectedProjects.contains(project))
			fSelectedProjects.remove(project);
	}
	
	void removeAllProjects() {
		fSelectedProjects.clear();	
	}
	
	/* (non-Javadoc)
	 * @see org.eclipse.jface.wizard.IWizard#canFinish()
	 */
	public boolean canFinish() {
		
		
		IWizardContainer container = getContainer();
		
		if ((container == null) || container.getCurrentPage().equals(fJCWPage))
			return false;
			
		return super.canFinish();
	}
}
