Primefaces Dialog Tabview

Question

I have a dialog where there are 2 tabviews, I click to display the dialog and switch between tabs, after closing if return to Tabview it returns with the last tab visited and I need it to return to the first tab. I tried with activeIndex, it works the first time, but if close and return it again displays with the last visited tab.

Suggestions?

Answer 1

I was able to solve with more this method:

public UIComponent findComponent(final String id) {

        FacesContext context = FacesContext.getCurrentInstance();
        UIViewRoot root = context.getViewRoot();
        final UIComponent[] found = new UIComponent[1];

        root.visitTree(new FullVisitContext(context), new VisitCallback() {
            @Override
            public VisitResult visit(VisitContext context, UIComponent component) {
                if (component.getId().equals(id)) {
                    found[0] = component;
                    return VisitResult.COMPLETE;
                }
                return VisitResult.ACCEPT;
            }
        });

        return found[0];

    }

You can try as follows: create a method to open the dialog and set the value of activeIndex directly by the bean.

public void abrirDialog() {
    UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();
    UIComponent componente = viewRoot.findComponent("idTabView");
    TabView tabView = (TabView) componente;
    tabView.setActiveIndex(0); //Vai abrir a primeira aba
    RequestContext.getCurrentInstance().update(componente.getClientId());
    RequestContext.getCurrentInstance().execute("PF('widgetVarDialog').show();");
}
