eclipse - disable back button on in ltk wizardinputpage -


i'm doing plugin in eclipse ide in order refactoring. i'm using ltk, point is: don't know how can disabled button after preview. i've tried create refactoringwizard using flags 'no_back_button_on_status_dialog', think not rigth way it.

the poblem have in background when push preview , push back, , preview again, preview box shows change related refactoring twice!.

i think best solution disabling button after preview because solution have seen in others plugins.

sorry because of english , beforehand.

the method org.eclipse.jface.wizard.wizarddialog#updatebuttons disables button when currentpage.getpreviouspage() returns null. so, suggest override method org.eclipse.ltk.ui.refactoring.refactoringwizard#getpreviouspage return null.
