Description Coly Yong Li 2008-07-31 08:51:07 UTC 
Here is what I expected,
1) on overview page, BackButton should be hiden by calling Wizard::HideBackButton(). Because on top level page, AbortButton can be same effect as BackButton.
    Wizard::SetContentsButtons(caption, contents, HELPS["Status_help"]:"",
            Label::BackButton(), Label::FinishButton());
    Wizard::HideBackButton();
2) if user switch to other second level page, BackButton should be there. This time without hiding BackButton:
    Wizard::SetContentsButtons(caption, contents, HELPS["Defaults_help"]:"",
            Label::BackButton(), Label::OKButton());

The code works correctly on gtk or qt interface, but incorrectly on ncurse interface.
In ncurse interface, if Wizard::HideBackButton() gets called, the BackButton will always be hiden, unless another Wizard::RestoreBackButton() gets called.

This is what I encountered during fix #398498 for yast2-multipath. In the new checked in code, the incorrect behavior of Wizard::HideBackButton() can be observed in ncurse interface.

Fixed in svn r49766. The fix will be in version 2.17.10 of yast2.
