OAF Controller Functions

1. Deriving Various Bean values

a. messageStyledText

OAMessageStyledTextBean lvariable = (OAMessageStyledTextBean)webBean.findChildRecursive("column1");

b. messageTextInput

OAMessageTextInputBean lvariable = (OAMessageTextInputBean)webBean.findChildRecursive("column1");

c. messageChoice

OAMessageChoiceBean lvariable = (OAMessageChoiceBean)webBean.findChildRecursive("column1");

d. messageLovInput

OAMessageLovInputBean lvariable = (OAMessageLovInputBean)webBean.findChildRecursive("column1");

e. submitButton

OASubmitButtonBean lvariableSubmitButton = (OASubmitButtonBean)webBean.findChildRecursive("submitButton1");

f. button

OAButtonBean lvariableButton = (OAButtonBean )webBean.findChildRecursive("button1");

2. To commit the database transactions

getTransaction().commit();

3. To discard the database transactions

getTransaction().rollback();

4. To Forward a page from one screen to another

if (pageContext.getParameter("nextPage")!=null) {

      pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/fnd/framework/newpage/webui/xxSearchPG",
                                           null,
                                           OAWebBeanConstants.KEEP_MENU_CONTEXT,
                                           null,
                                           params,
                                           true, // retain AM
                                           OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
     

    }

5. To initiate an Application Module (AM)

xxSearchAMImpl am = (xxSearchAMImpl)pageContext.getApplicationModule(webBean);
 
am.invokeMethod("apply");

6. To put a session value

pageContext.putSessionValue("currentPage","Page1");

7. To get a session value

String variableNew = (String)pageContext.getSessionValue("variableOld");

8. To hide a button/submit button using the Render property

OASubmitButtonBean SaveVariable = (OASubmitButtonBean)webBean.findChildRecursive("button1");

SaveVariable.setRendered(false);

SaveVariable.setRendered(true);

9. Forming Dynamic Parameter in Controller

HashMap params = new HashMap(1);
params.put("PageMode","CREATE");

      if ( pageContext.getParameter("PageMode")!=null && pageContext.getParameter("PageMode").equals("CREATE")  )

       {
     
System.out.println("Page for Create Action");

 am.invokeMethod("createRecord");

//Set Parameter value for PageMode back to Original State.
             
           HashMap params = new HashMap(1);
           params.put("PageMode","NULL");
         
         }
