Showing highlighted holiday calendar in af:inputDate date picker (ADF 12.1.3)

Hello All
This post is about showing highlighted days for holidays in af:inputDate and user must not be able to select these dates
here i am using Jdeveloper 12.1.3
you can do this using af:calendar
https://blogs.oracle.com/adf/entry/display_holiday_name_in_af
but i have a requirement to show holidays while user selects date using af:inputDate

so for this requirement first step is easy to do and there is lots of post about disabling specific days in calendar of af:inputDate

Step 1. Disable specific days -
  • you can see there is property in af:inputDate for setting disabled days, this filed takes a value of type List supported by DateListProvider interface




  • for this purpose i have created a bean that implements methods of DateListProvider , in Overridden method i have defined a list that contains dates of holidays that i want to disable in af:inputDate

  • package holiday.view.bean;
    
    import java.util.ArrayList;
    import java.util.Calendar;
    import java.util.Date;
    import java.util.List;
    
    import javax.faces.context.FacesContext;
    
    import org.apache.myfaces.trinidad.model.DateListProvider;
    
    public class HolidayBean implements DateListProvider {
        public HolidayBean() {
        }
    
        @Override
        public List<Date> getDateList(FacesContext facesContext, Calendar calendar, Date date, Date date2) {
            List<java.util.Date> holiDay = new ArrayList();
            holiDay.add(new Date("27-July-2014"));
            holiDay.add(new Date("29-July-2014"));
            holiDay.add(new Date("10-Aug-2014"));
            holiDay.add(new Date("25-Dec-2014"));
            holiDay.add(new Date("01-Jan-2015"));
            holiDay.add(new Date("22-Oct-2014"));
            holiDay.add(new Date("23-Oct-2014"));
            holiDay.add(new Date("24-Oct-2014"));
    
            return holiDay;
            //return Collections.emptyList();
        }
    }
    

  • attached this bean to disabledDays property of af:inputDate


  • now first part is done we can see all holidays as disabled in calendar of af:inputDate

Step 2. Highlight disabled holidays -
  • but it is not easy to find holidays as all are in grey, so i have to highlight all disabled days , so for this requirement , create a skin in viewController project and write this

  • af|chooseDate::regular-day:disabled{
        background-color: red;
        color: ButtonFace;
    }
    

  • af:chooseDate is used because internally af:inputDate opens af:chooseDate as date picker so i have to change property of af:chooseDate, now run your application

Happy Learning :)

Search on (Filtering) child nodes of af:treeTable using viewCriteria in Oracle ADF (11g,12c)

Hello all
this post is about filtering treeTable on basis of child nodes in Oracle ADF
in this tutorial i have used Departments and Employees table of HR schema to create treeTable
see how to create treeTable-
http://www.awasthiashish.com/2012/11/tree-table-component-in-oracle.html
http://www.awasthiashish.com/2013/08/tree-table-component-with-declarative.html

treeTable look like this-


now next is to search on Employee Names



  • i have dropped a input text for search string and a button to search on page , here i am searching on first name of employees 


  • now created a view Criteria in Employee viewObject to search on first name


  • This viewCriteria doesn't work directly on Employee viewObject, to search in treeTable we have to override createViewLinkAccessorRS method in Departments (master vo) VOImpl class, and in this method we have to call Employees ViewCriteria explicitly , this will filter Employee Vo Rowset as per bind-variable value when a node is disclosed at runtime

  •     /**
         * @param associationDefImpl
         * @param viewObjectImpl
         * @param row
         * @param object
         * @return
         */
        protected ViewRowSetImpl createViewLinkAccessorRS(AssociationDefImpl associationDefImpl,
                                                          ViewObjectImpl viewObjectImpl, Row row, Object[] object) {
    
    
            ViewRowSetImpl viewRowSetImpl = super.createViewLinkAccessorRS(associationDefImpl, viewObjectImpl, row, object);
    
            String firstName = getFirstNm();
            ViewCriteriaManager vcm = viewObjectImpl.getViewCriteriaManager();
            ViewCriteria vc = vcm.getViewCriteria("EmployeesVOCriteria");
            VariableValueManager vvm = vc.ensureVariableManager();
            vvm.setVariableValue("BindFirstNm", firstName);
            viewObjectImpl.applyViewCriteria(vc);
            return viewRowSetImpl;
    
    
            // return super.createViewLinkAccessorRS(associationDefImpl, viewObjectImpl, row, object);
        }
    

  • to pass bind-variable value i have created a variable and it's accessors in VoImpl and exposed set method to client that is further used by managed bean

  •     private String firstNm;
        public void setFirstNm(String firstNm) {
            this.firstNm = firstNm;
        }
    
        public String getFirstNm() {
            return firstNm;
        }
    

  • now this setter method is called in managed bean search button action to set bind variable value

  •     /**Method to search in treeTable childs
         * @param actionEvent
         */
        public void searchAction(ActionEvent actionEvent) {
            if (firstNmBind.getValue() != null) {
                OperationBinding ob = executeOperation("setFirstNm");
                // firstNmBind is binding of inputText
                ob.getParamsMap().put("firstNm", firstNmBind.getValue().toString());
                ob.execute();
                /* Method Expand treeTable after Search see- 
                 http://www.awasthiashish.com/2013/10/expand-and-collapse-aftreetable.html*/
                expandTreeTable();
                AdfFacesContext.getCurrentInstance().addPartialTarget(treeTabBind);
    
            }
        }

Populate af:treeTable programatically using POJO in Oracle ADF (11g & 12c)

Hello All
This post is about creating & populating af:treeTable programmatically in ADF 11g and 12c
treeTable is basically a hierarchical representation of data, using ADF model layer we can create treeTable very easily by defining master-detail relation between viewObjects
see my previous posts on treeTable-
Tree Table Component in Oracle ADF(Hierarchical Representation)
Tree Table Component with declarative presentation in ADF, Access childs without custom selection listener
Expand and Collapse an af:treeTable programmatically in ADF Faces (Oracle ADF)
Refreshing Child Nodes of an af:treeTable / af:tree in Oracle ADF



to populate treeTable programmatically we need to configure data set that fits to tree hierarchy
thanks to Chris Muir's post about programmatic creation of treeTable
http://one-size-doesnt-fit-all.blogspot.in/2007/05/back-to-programming-programmatic-adf.html

there is 4-5 simple steps to do-
  • Create a fusion web application and drop a af:treeTable on page , in treeTable creation wizard select "bind later" 


  • now create managed bean to populate data in treeTable, create a simple List in managed bean of type POJO class (a java class that contains attributes and their accessor  )
  • so in this app i am going to Tv Serial and respective character names in treeTable, for that i have created a class that contains POJO for treeTable

  • import java.util.ArrayList;
    import java.util.List;
    
    
    public class Seasons {
        public Seasons(String name) {
            this.name = name; // To Store Header Values (Storing Seasons Name :))
            characters = new ArrayList<Seasons>(); // To Store Detail Values (Storing Season's Charatcers)
        }
    
        public void setCharacters(List<Seasons> empDet) {
            this.characters = empDet;
        }
    
        public List<Seasons> getCharacters() {
            return characters;
        }
        private String name;
        private List<Seasons> characters;
    
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getName() {
            return name;
        }
    // This methods directly add characters value in list
        public void addEmp(Seasons employee) {
            characters.add(employee);
        }
    
    }
    

  • In this class the characters list behaves as child of seasons, so in managed bean define a top-level list (that contains both master and detail) and add values

  • See managed Bean Code-
    import java.util.ArrayList;
    import java.util.List;
    
    import org.apache.myfaces.trinidad.model.ChildPropertyTreeModel;
    
    public class ProgrammaticTreeTabBean {
        List<Seasons> seasonList = new ArrayList<Seasons>();
    
        ChildPropertyTreeModel charatcerVal;
    
        public ProgrammaticTreeTabBean() {
            super();
            // Creating tree for Seasons and Characters details
            // Adding Master Values (seasons)
            Seasons season1 = new Seasons("Game of Thrones");
           // Adding Detail Values (Child Node-Characters)
            Seasons character = new Seasons("Tywin Lannister");
            season1.addCharaters(character);
            character = new Seasons("Tyrion Lannister");
            season1.addCharaters(character);
            character = new Seasons("Jaime Lannister");
            season1.addCharaters(character);
            character = new Seasons("Cersie Lannister");
            season1.addCharaters(character);
            character = new Seasons("Ned Stark");
            season1.addCharaters(character);
    
            // Adding Master Values (seasons)
            Seasons season2 = new Seasons("Arrow");
            // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Oliver Queen");
            season2.addCharaters(character);
            character = new Seasons("Moira Queen");
            season2.addCharaters(character);
            character = new Seasons("Laurel Lance");
            season2.addCharaters(character);
            character = new Seasons("Sara Lance");
            season2.addCharaters(character);
    
            // Adding Master Values (seasons)
            Seasons season3 = new Seasons("Vikings");
          // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Ragnar Lothrak");
            season3.addCharaters(character);
    
            // Adding all list to topList
            seasonList.add(season1);
            seasonList.add(season2);
            seasonList.add(season3);
            // Filtering Child Data, ChildPropertyTreeModel creates a TreeModel from a List of beans, see
            // https://myfaces.apache.org/trinidad/trinidad-api/apidocs/org/apache/myfaces/trinidad/model/ChildPropertyTreeModel.html
            charatcerVal = new ChildPropertyTreeModel(seasonList, "characters");
        }
    
        public ChildPropertyTreeModel getCharatcerVal() {
            return charatcerVal;
        }
    }
    

  • Now code part is complete, now configure your treeTable to show data, see XML source of af:treeTable

  • <af:treeTable rowBandingInterval="0" id="tt1"
                                  value="#{pageFlowScope.ProgrammaticTreeTabBean.charatcerVal}" var="node"
                                  rowSelection="single" initiallyExpanded="true">
                        <f:facet name="nodeStamp">
                            <af:column headerText="Node Stamp" id="c1" width="250">
                                <af:outputText value="#{node.name}" id="ot1" inlineStyle="font-weight:bold;"/>
                            </af:column>
                        </f:facet>
                    </af:treeTable>
