Create Partial Fire action on DFF context value in controller extension

Question

Hi All,
I have a requirement where I will have to default the DFF attribute value based on the context value chosen in the same DFF.
Since the page is a seeded page i have done that using Controller Extension.
I have followed the below steps.
1.I have created one class file XXR2R_AR_BANK_ACCT_EXTCO
2. In that file I have written the following piece of code
+public class XXR2R_AR_BANK_ACCT_EXTCO extends UpdateExtBankAcctCO {+
public void processRequest(OAPageContext oapageContext,
OAWebBean webBean)
+{+
super.processRequest(oapageContext, webBean);
OADescriptiveFlexBean dfb =
+(OADescriptiveFlexBean)webBean.findChildRecursive("FlexField");+ // This is the ID of the flexfield defined in seeded page
FireAction firePartialAction = new FirePartialAction("contextvalchng");
+}+
public void processFormRequest(OAPageContext pageContext,OAWebBean webBean)
+{+
super.processFormRequest(pageContext, webBean);
if ("contextvalchng".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
+{+              
super.processFormRequest(pageContext, webBean);
OADescriptiveFlexBean dffBean =
+(OADescriptiveFlexBean)webBean.findChildRecursive("FlexField");+
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject extVO =
+(OAViewObject)am.findViewObject("ExtBankAccountsVO");+ *// This is the view name corresponding to the DFF fields*
String str = "" ;
OARow row = null;
if (extVO!=null)
+{+
row = (OARow) extVO.getCurrentRow();
if (row!=null)
+{+
str = (String)row.getAttribute("ATTRIBUTE_CATEGORY"); *// here I have retrieved the context value of the DFF*
+}+
+}+
dffBean.processFlex(pageContext);
if ("DEN".equals(str)) *// if the context value is "DEN" then only the defaulting will be done*
+{+
OAMessageTextInputBean mnum = (OAMessageTextInputBean)webBean.findChildRecursive("FlexField1");
mnum.setText("599956");
row.setAttribute("ATTRIBUTE13","6995");
+}+
3. After compiling the .jave file I have placed the .class file in the CUSTOM_JAVA_TOP location and in the seeded page I have placed this CUSTOM_JAVA_TOP top path (in the personalize page section)exactly in the same way where the .class file is.
But when I am changing the context value in the DFF nothing is actually happening.It is never including the custom file behavior.
Please let me know if I am wrong in my coding or my approach.
Thanks
Sudie

Hi,
I think you need to set PPR on one of the segment of the DFF. Following is the code snippet I found few days back in forum. Use this in processRequest() method to set the PPR.
OADescriptiveFlexBean oadescriptiveflexbean = (OADescriptiveFlexBean)webBean.findIndexedChildRecursive("ASNPrdtAddInfoFF"); //DFF ID...in your case it is "FlexField"
if(null != oadescriptiveflexbean)
     oadescriptiveflexbean.processFlex(pageContext);
     //oadescriptiveflexbean.setFlexTableRendered(false); -- useful, if we want to render the items on our own.
     int cnt = oadescriptiveflexbean.getIndexedChildCount(pageContext.getRenderingContext());
     for(int i=0; i<cnt; i++)
          OAWebBean uiNode = (OAWebBean)oadescriptiveflexbean.getIndexedChild(pageContext.getRenderingContext(),i);
          if(null != uiNode && uiNode instanceof OAMessageTextInputBean )
               System.out.println(i + "::::" + uiNode.getLabel() + "::::" + uiNode.getUINodeName()+ "\n");
               if(uiNode.getUINodeName().equalsIgnoreCase("ASNPrdtAddInfoFF2")) //Segment ID...you need to find it out..on which segment you want to do PPR
                    FireAction firePartialAction = new FirePartialAction("Event.termChangeEvent", true); //This is I am not sure but it must be the event name
                    uiNode.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR,firePartialAction);
Now you need to check for this event in processFormRequest() method. If this event fetched iterate the Vo rows and check the Attribute value there. if the value matched then do the defaulting process.
Hope this helps..
