How to trap Submit button event in OAF

Question

Hello,
I'm doing controller extension for create account button in Customer UI.
Issue: I'm not able to trap the table action to add extra validation logic.
I tried to use pageContext.getParameters("CreateButton") but it didn't work i.e. debug message was not printed written inside if statement.
Button Structure:
TableAction
Flowlayout
Submit button.
Code:
public void processFormRequest(OAPageContext pageContext,
                                   OAWebBean webBean) {
        //super.processFormRequest(pageContext, webBean);
        OAApplicationModule am = pageContext.getApplicationModule(webBean);
        ArrayList exceptions = new ArrayList();
        OAFlowLayoutBean oaflowlaybean =
            (OAFlowLayoutBean)webBean.findChildRecursive("TableActionsRN");
        OASubmitButtonBean vbuttonBean =
            (OASubmitButtonBean)oaflowlaybean.findChildRecursive("CreateButton");
        String buttonId = vbuttonBean.getID();
        String buttonId12 = vbuttonBean.getName();
        String asd=vbuttonBean.getEvent();
        String s = pageContext.getParameter(EVENT_PARAM);
        String s1 = pageContext.getParameter(vbuttonBean.getName());
            if (s.equalsIgnoreCase("CreateAccount")) {
            OAViewObject vo =
                (OAViewObject)am.findViewObject("HzPuiAccountTableVO");
            if (vo != null) {
                pageContext.writeDiagnostics("Jai-1", "VO Found", 1);
                OARow row = (OARow)vo.getCurrentRow();
                if (row != null) {
                    pageContext.writeDiagnostics("Jai-2", "Row Found", 1);
                    String partyid =
                        (String)row.getAttribute("PartyId").toString();
                    pageContext.writeDiagnostics("Jai-3", "PartyId" + partyid,
                                                 1);
                    int PartyNum = Integer.parseInt(partyid);
                    String partyacctcnt = null;
                    try {
                        OracleConnection conn =
                            (OracleConnection)pageContext.getApplicationModule(webBean).getOADBTransaction().getJdbcConnection();
                        pageContext.writeDiagnostics("Jai-4", "Inside Try", 1);
                        String query =
                            "SELECT count(1) lcount  FROM HZ_CUST_ACCOUNTS WHERE party_id=:1";
                        PreparedStatement stmt = conn.prepareStatement(query);
                        stmt.setInt(1, PartyNum);
                        ResultSet resultset = (ResultSet)stmt.executeQuery();
                        if (resultset.next()) {
                            pageContext.writeDiagnostics("Jai-5",
                                                         "Inside Result Next",
                                                         1);
                            partyacctcnt = resultset.getString("lcount");
                        stmt.close();
                    } catch (SQLException sqlexception) {
                        throw OAException.wrapperException(sqlexception);
                    int i = Integer.parseInt(partyacctcnt);
                    /*   String HoldFlag = (String)row.getAttribute("Attribute11");
                    // Check Hold Flag: "Y" then restrict to create new account
                    if (HoldFlag == "Y") {
                        pageContext.writeDiagnostics("Jai", "Inside Hold Flag", 1);
                        exceptions.add(new OAException("XXGCO",
                                                       "XXTCO_CREDIT_LIMIT_CHECK",
                                                       null, OAException.ERROR,
                                                       null));
                    // One Party-One Account: Greater or Equal to 1 then throw error mesaage
                    if (i > 1) {
                        pageContext.writeDiagnostics("Jai-6",
                                                     "Inside Account Check",
                                                     1);
                        exceptions.add(new OAException("XXGCO",
                                                       "XXTCO_CREDIT_LIMIT_CHECK",
                                                       null, OAException.ERROR,
                                                       null));
                    if (exceptions.size() > 0) {
                        pageContext.writeDiagnostics("Jai-7",
                                                     "Inside Exceptioon calling",
                                                     10);
                        OAException.raiseBundledOAException(exceptions);
                    } else {
                        pageContext.writeDiagnostics("Jai-8",
                                                     "Inside else Exceptioon calling",
                                                     10);
                       // super.initParametersPFR(pageContext,webBean);
                        vbuttonBean.setFireActionForSubmit(null, null, null, false);
                        super.processFormRequest(pageContext, webBean);
Please suggest the how to overcome with above mention issue.

Hi Kiranmai,
You can capture the event of the radio button in the following way in oninputprocessing.
DATA: event             TYPE REF TO if_htmlb_data,
               radioButton_event TYPE REF TO CL_HTMLB_EVENT_RADIOBUTTON.
         event = cl_htmlb_manager=>get_event( request ).
         IF event IS NOT INITIAL AND event->event_name = htmlb_events=>radiobutton.
           radioButton_event ?= event.
           ENDIF.
you can get the attributes of clicked radio button in
event->event_class
event->event_id.
event->event_name
event->event_type
event->event_server_name
In layout define the radio button as
<htmlb:radioButtonGroup   id          = "test_id">
        <htmlb:radioButton      id          = "id_red"   text = "Red"               onClick="myClick" />
        <htmlb:radioButton      id          = "id_blue"  text = "Blue"          onClientClick="alert('blue clicked')"/>
        <htmlb:radioButton      id          = "id_green" text = "Green"      onClick="myClick" onClientClick="alert('green clicked')"/>
      </htmlb:radioButtonGroup>
Hope this will solve your problem.
