3. Create a OA components Pages

TrainDemoProj right click > New > OA Components > Page

Name – TrainDemoPG1

Package -- prajkumar.oracle.apps.fnd.traindemo.webui

 

4. Modify the Page Layout (Top-level) Region

Create Text Items for all three pages say TextItemPage1, TextItemPage2 and TextItemPage3 in respective pages TrainDemoPG1, TrainDemoPG2 and TrainDemoPG3 in similar way of as mention below to create TextItemPage1 in page TrainDemoPG1

6. Create Text Items

Select MainRN right click > New > messageTextInput

Prompt – TextItemPage1

Length -- 20

 

7. Create a Standalone Train Region

TrainDemoProj > New > Web Tier > OA Components > Region

Name -- TrainRN

Package – prajkumar.oracle.apps.fnd.traindemo.webui

Style – train

Select TrainRN inStructure pane and open property inspector and set Allow Interaction property to True

 

8. Add Three Train Nodes to TrainRN

Right Click on TrainRN in Structure pane > New > Link

Set the link properties as follow --

ID – TrainStep1

Item Style – link

Text – Step 1

Destination URI – OA.jsp?page=/prajkumar/oracle/apps/fnd/traindemo/webui/TrainDemoPG1

 

Right Click on TrainRN in Structure pane > New > Link

Set the link properties as follow --

ID – TrainStep2

Item Style – link

Text – Step 2

Destination URI – OA.jsp?page=/prajkumar/oracle/apps/fnd/traindemo/webui/TrainDemoPG2

 

Right Click on TrainRN in Structure pane > New > Link

Set the link properties as follow --

ID – TrainStep3

Item Style – link

Text – Step 3

Destination URI – OA.jsp?page=/prajkumar/oracle/apps/fnd/traindemo/webui/TrainDemoPG3

 

9. Add Train Region to each of your Pages

For each of three pages in multistep flow, right click the pageLayoutRN in structure panel, and select New > location from page Context menu

Set following properties as follow --

ID – TrainDemoRN

Extends -- /prajkumar/oracle/apps/fnd/traindemo/webui/TrainRN

 

10. Create a Standalone (Shared) TrainFooterRN

TrainDemoProj > New > Web Tier > OA Components > Region

Name -- TrainFooterRN

Package -- prajkumar.oracle.apps.fnd.traindemo.webui

Region Style -- pageButtonBar

 

11. Add navigrationBar

Select TrainFooterRN in Structure pane right click > New > Region

Set the region properties as follows:

ID -- NavBar

Region Style – navigationBar

First Step – 1

Last Step – 3

 

12. Add Links to the navigrationBar

Right Click on NavBar > New > link

Set Item’s properties as follows:

ID – Step1Link

Item Style – link

Destination URI -- /prajkumar/oracle/apps/fnd/traindemo/webui/TrainDemoPG1

 

Right Click on NavBar > New > link

Set Item’s properties as follows:

ID – Step2Link

Item Style – link

Text – Step 2 of 3: Page2

Destination URI -- /prajkumar/oracle/apps/fnd/traindemo/webui/TrainDemoPG3

 

13. Initialize the Footer Region

Select TrainFooterRN in Structure pane right click > Set New Controller

Class Name -- TrainDemoCO

Package Name – prajkumar.oracle.apps.fnd.traindemo.webui

Add following code in processRequest()

 

import oracle.apps.fnd.framework.webui.beans.nav.OATrainBean;
import oracle.apps.fnd.framework.webui.beans.nav.OANavigationBarBean;
...

public void processRequest(OAPageContext pageContext, OAWebBean webBean)
{
 super.processRequest(pageContext, webBean);

 OATrainBean trainBean =
  (OATrainBean)pageContext.getPageLayoutBean().getLocation();

 trainBean.prepareForRendering(pageContext);
 
 int step = trainBean.getSelectedTrainStepRenderedIndex();

 OANavigationBarBean navBean =
  (OANavigationBarBean)webBean.findChildRecursive("NavBar");

 navBean.setValue(step+1);
} // end processRequest()

 

14. Add the Navigation Region to your pages

For each of three pages in the multistep flow, right click the PageLayoutRN in Structure pane and select New > Region
