Better User Interface- Oracle Alta UI for Oracle ADF 12.1.3

Great news for all ADF developers ,
Oracle has launched a design system for better user experience - Oracle Alta UI (much more than skin)

see press release- Oracle Announces New User Interface Design System for a More Engaging Customer Experience
As per documentation -

Oracle Alta UI is a new user interface design system that enables developers to create modern, visually pleasing, consistent, and engaging interfaces that can be easily distributed across all delivery channels.
The Oracle Alta UI design system provides a set of guidelines and best practices. The system is based on years of user experience and usability implementations and analysis by leading UI and design specialists.
Oracle Alta UI-based applications feature a simplified component structure and more open space to keep the focus on data.

See details of Oracle Alta UI- Oracle Alta UI

I have created a simple master detail page using Departments and Employees table of HR Schema using Jdev 12.1.3



by default skyros skin is applied in fusion web application, you can see this in trinidad-config.xml file under WEB-INF node




to apply Oracle Alta UI just change skin-family to alta


Now compare both UI , you will see a big difference

Full page-
Default Skin-

Alta UI-



See difference in af:inputDate and it's calendar
Default Skin-

 Alta UI- (icon is inside date field)

inputListofValues box is very attractive now-
Default Skin-

 Oracle Alta UI-
and magnifier icon is inside field now-

try it yourself and see difference in other components also

Tree Table Component with declarative presentation in ADF, Access childs without custom selection listener

Hello all,
this is my second post on af:treeTable, first post was about creating and overriding tree table selection listener to get node value in managed bean, see
Tree Table Component in Oracle ADF(Hierarchical Representation)

In this post i am going to explain how to
  • use multiple detail column in treeTable
  • design better UI
  • manage child rows
  • use link,image,checkbox in treeTable conditionally
so i assume that you all know about creating treeTable, i am using default HR Schema (Employees ,Departments table) to master detail relation in tree and i have to show detail of Employee under Department node
  • I have created a treeTable using following details of Employees VO
  • Now on running my page it is looking like this, very odd and complex view
        xml source-

  <af:treeTable value="#{bindings.Departments1.treeModel}" var="node"
                              selectionListener="#{bindings.Departments1.treeModel.makeCurrent}" rowSelection="single"
                              id="tt1">
                    <f:facet name="nodeStamp">
                        <af:column id="c1" width="500">
                            <af:outputText value="#{node}" id="ot1"/>
                        </af:column>
                    </f:facet>
                    <f:facet name="pathStamp">
                        <af:outputText value="#{node}" id="ot2"/>
                    </f:facet>
                </af:treeTable>

  • It shows that all details of employees are clubbed in one column that is nodestamp, now to show details in different columns i have added 5 columns in treeTable, and seperate detail in each column as Email, FirstName,LastName etc
    To add column right click on treeTable and insert-
 In column drop an input text and set its value taking node reference




  •  Now run page and see, there is now 5 column with different details but still that clubbed value is shown.
  • Now to remove that clubbed detail, go to nodestamp facet of treeTable and see value of output text inside column, it is set to #{node} ,due to this all values available in node are clubbed and displayed in page, now we have to set its value to any of Master table's (Departments) attribute



  •  Now run page , only department name is displayed on header, and corresponding value for detail is blank
  •  We are done with this part, now try to make its UI somewhat better using some styles, so i have used different background color for header and detail part of treeTable conditionally
  • To do this i have set inline style property conditionally , because i have to change color of same column according to master and detail data, see condition

  • #{node.DepartmentName!=null ? 'background-color:darkgreen' :  'background-color:rgb(239,255,213);'  }
    

  • Now see how to get selected child row without over-riding treeTable's selection listener, to do this i have added a image link in treeTable and created a action listener on that to show current selected detail row
  • Bind tree table to managed bean and create two methods to get selected RowIterator and node Key

  •     /**Tree Table Binding in managed bean*/
        private RichTreeTable treeTabBind;
    
        public void setTreeTabBind(RichTreeTable treeTabBind) {
            this.treeTabBind = treeTabBind;
        }
    
        public RichTreeTable getTreeTabBind() {
            return treeTabBind;
        }
    
        /**Method to get Iterator*/
        public RowIterator getSelectedNodeIterator() {
            if (getTreeTabBind() != null && getTreeTabBind().getSelectedRowKeys() != null) {
                for (Object rKey : getTreeTabBind().getSelectedRowKeys()) {
                    getTreeTabBind().setRowKey(rKey);
                    return ((JUCtrlHierNodeBinding)getTreeTabBind().getRowData()).getRowIterator();
                }
            }
            return null;
        }
    
        /**Method to get Node Key*/
        public Key getSelectedNodeKey() {
            if (getTreeTabBind() != null && getTreeTabBind().getSelectedRowKeys() != null) {
                for (Object rKey : getTreeTabBind().getSelectedRowKeys()) {
                    getTreeTabBind().setRowKey(rKey);
                    return ((JUCtrlHierNodeBinding)getTreeTabBind().getRowData()).getRowKey();
                }
            }
            return null;
        }
    

  • Now to get currently selected node and row pass Iterator and Node key in this method- see

  •     public void showCurRowDetail(RowIterator ri, Key selectedNodeKey) {
            Row[] rows = ri.findByKey(selectedNodeKey, 1);
    
            FacesMessage msg = new FacesMessage(rows[0].getAttribute("FirstName") + "'s data available in this row");
            FacesContext.getCurrentInstance().addMessage(null, msg);
        }
    

  • Now Run application and click on link to see selected row -
