Examples of javax.faces.component.UIData.visitTree()

javax.faces.component.UIData.visitTree()
Overrides the behavior in UIComponent.visitTree(javax.faces.component.visit.VisitContext, javax.faces.component.visit.VisitCallback) to handle iteration correctly. @param context the visit context which handles the processing details @param callback the callback to be performed @return false if the processing is not done true if we can shortcutthe visiting because we are done with everything @since 2.0

    int originalRows = table.getRows();
    table.setRows(0); // We want to visit all rows.


    FacesContext context = FacesContext.getCurrentInstance();
    UniqueColumnValueChecker checker = new UniqueColumnValueChecker(table, input);
    table.visitTree(VisitContext.createVisitContext(context), checker);
    table.setRows(originalRows);


    if (checker.isDuplicate()) {
      input.setValid(false);
      context.validationFailed();
