It doesn't abort the module; it makes UI::OpenDialog() fail. You could easily catch that in YCP code (but it's not done anywhere in production code): http://svn.opensuse.org/svn/yast/trunk/ycp-ui-bindings/examples/ButtonBox2.ycp void showDialog( term buttonBox ) { boolean success = (boolean) UI::OpenDialog( `VBox( `HVCenter( `Label( "Hello, World!" ) ), buttonBox ) ); // Most YCP developers never use the return value of UI::OpenDialog(). // Many of them probably don't even know that it has a return value. // // Used properly, that return value can be used to recover from error // situations that would otherwise abort the program - like in this //case. if ( success ) { UI::UserInput(); UI::CloseDialog(); } } Past experience shows that y2warning() calls are generally ignored, so they are pretty useless.
