OAF useful codes

1-  Depending upon user's action (Yes or No) on dialog page, we can commit or rollback the transaction.




// in processFormRequest() method:

// On clicking save button, we create a dialog page and redirect there.

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

    OAException descMesg =

        new OAException("FND", "FND_CUSTM_SAVE_CHANGES");

    OAException instrMesg =

        new OAException("FND", "FND_CUSTM_SAVE_CHANGES");

    OADialogPage dialogPage =

        new OADialogPage(OAException.WARNING, descMesg, instrMesg, "",

                         "");

    dialogPage.setOkButtonToPost(true);

    dialogPage.setNoButtonToPost(true);

    dialogPage.setPostToCallingPage(true);

    // here we are setting names of buttons of dialog page

 dialogPage.setOkButtonItemName("SaveYes");

    dialogPage.setNoButtonItemName("SaveNo");

     

 pageContext.redirectToDialogPage(dialogPage);

}

// if user clicks Yes button, we are committing

// records and show confirmation message

else if (pageContext.getParameter("SaveYes") != null) {

    am.invokeMethod("saveRecords");

    throw new OAException("Data has been saved successfully.",

                          OAException.CONFIRMATION);

}

// if user clicks No button, we undo the changes

// i.e. rollback the transaction

else if (pageContext.getParameter("SaveNo") != null) {

    am.invokeMethod("undoChanges");

}










// In AMImpl.java:

// these are method for committing and rollbacking the transactions:

public void saveRecords() {

    getOADBTransaction().commit();

}

public void undoChanges() {

    getOADBTransaction().rollback();

}
