Unable to set DFF context value

Hi,
i want to set DFF context value with a variable, so i tried first to set it with a constant.
in the controller's PR
super.processRequest(oapagecontext, oawebbean);
// first, find the flexfield's handle
OADescriptiveFlexBean oaDFF;
oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("DescFF");
oapagecontext.writeDiagnostics(this,"oaDFF=>"+oaDFF ,1);
// default the Attribute Category (DFF context)
oaDFF.setFlexContext(oapagecontext,"QuietanzaErarioStato");
oaDFF.processFlex(oapagecontext);
but it doesn't take any effect, the context's pickilist remains blank.
However i tried the same code with another DFF and it worked. i am wondering if there is some differences between the two DFF.
Any help will be appreciated, it'quite urgent
Thanx

Hi,
Please create a new region thru personalization before the region where u r DFF is present. Use re-order to take the new region before the DFF region.
Set the controller to that new region and the code that you mentioned. This process will sets the context.
Kindly refer the dev guide as i found the above solution from devguide it self.
Thanks

Unable to set the selected value for a ADF LOV

Hi,
I am developing an application using jdeveloper 10.1.3 and Struts.
I have created a ADF LOV on my JSP Page as given below:
<html:select property="lob" onchange="javascript:selectLOB(this.form)">
<html:optionsCollection label="prompt" value="index" property="lob.displayData"/>
</html:select>
When i submit the form, i am able to get the value of the selected Value in the List.
JUCtrlListBinding listBinding = (JUCtrlListBinding) formBean.get("Lob");
Row r = (Row) listBinding.getSelectedValue();
String SoLob = (String) r.getAttribute("LobLob");
But i am unable to set the selected value back in the list when i return to the form again.
I tried the following:
int x = listBinding.getSelectedIndex();
listBinding.setSelectedIndex(x);
It would be really helpful if some one could let me know what needs to be done.
Thanks,

Gyan,
I tried with the code you suggest , its trying to set the value of a field, but my requirement is to change the property for
"Rendered" on the field so that based on search parameters we can hide result table column.
After searching online, I modified the controller code as follows
1.Created a new transient attribute (Testrender) with type "Boolean" and always updateable.
2.changed the "Rendered" property value on the field I want to hide as ${oa.PoSearchVO1.Testrender}.
3. Modified the controller code as follows :
        OAApplicationModule am = pageContext.getApplicationModule(webBean);
        OAViewObject testvo = (OAViewObject)am.findViewObject("PoSearchVO1");
        OADBTransaction txn = am.getOADBTransaction();
        if (testvo != null)
          OARow row = (OARow)testvo.first();
            if (a.equalsIgnoreCase("Approved"))
                 row.setAttribute("Testrender", Boolean.FALSE);
            else
                 row.setAttribute("Testrender", Boolean.TRUE);
        } But now when i run the page and populate the search field and click "Go" its hiding the field but throwing the following error and the search results are also bad.
Its using only the value of one search parameter but not the second one .
The search cannot be executed because the table has pending changes that would be lost. I think the vo is getting dirty when I update the transient attribute value. So I used txn.rollback ,then search is working fine but its not hiding the field.
So can you please let me know how to proceed from here ?

Unable to set parent context for this record.

Has anyone seen this error when doing an import? In my case I was doing an import to the Opportunity Product record.
the full error message is
Unable to set parent context for this record. Please make sure that the parent record is valid and you have permission to modify the parent record.
I was attempting to populate one field on the record with data.

Hi,
Was there a resolution to this that you found, cause it's driving me crazy.
We've resorted to manually created a product in OnDemand with an EUI and exported it but we can't reimport it to overwrite it as we get the same error message "Unable to set parent context for this record"
The opty and the product both exist as they got manually created, although when you export them there are now 2 of them (I see this in reporting as well????)
Besides the Opty-Product External ID what else is required to do an import to overwrite?

Unable to set search context for AD resource

Hi,
I am unable to set a search context into my AD resource (IdM 8.1 patch 9, AD gateway).
When I traced the gateway - I found it completely ignores the context filter values I defined.
Anyone has solution?
R.

Hi,
I am not talking about a query but about a regular AD resource configuration - so there is no code to provide.
Try putting a context in AD resource (to search for specific type of users for example) and see if it works.

Create Partial Fire action on DFF context value in controller extension

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..

Person DFF Context Value based on 2 criteria (Business Group and Emp Type)?

Hello,
We're implementing HR module into multiple business groups.
I need to define context value for DFF "Additional Personal Details" based on 2 criteria Business Group ID and Employee Type
Any idea how to do it?
Thank you
Elie

Hello Elie,
I am not sure on it,However have you tried creating a context with combination of Business Group and Person Type using merging,
business_group_id || "_"|| person_type_id And structures would be something like 80_2112 Business Group id = 80 and Person Type id=2112.
It may resolve your issue if this works out.

Dynamically setting DFF Context

Hi Guys,
I have a requirement to dynamically set the DFF context in the CO of the page (depending on various circumstances)
I have used setFlexContext in the following code to successfully set the context for my DFF in the Requisition Headers page:
          //Set the context on the Requisition Header DFF.
          OADescriptiveFlexBean dffBean = (OADescriptiveFlexBean) webBean.findChildRecursive("XXNRReqHeaderDFF");
          try {
                    if (dffBean != null) {
                         pageContext.writeDiagnostics(this, "Ravi: Found XXNR DFF Bean. Setting Context to COOM", 4);
                         dffBean.setFlexContext(pageContext, "COOM");
                         dffBean.mergeSegmentsWithParent(pageContext);
                         dffBean.processFlex(pageContext);
                    else {
                         pageContext.writeDiagnostics(this, "Ravi: Did not find DFF Bean", 4);
          } catch (Exception e) {
               pageContext.writeDiagnostics(this, "Ravi: Could not set the Context", 4);
               e.printStackTrace();
This was a simple page with only one Header DFF instance and the code above works perfectly.
Now I wish to use the same code to set the DFF context on the Requisition Lines Page. The above code does not work there.
The problem is that in the lines page, the DFF gets replicated for each of the requisition Line on the page and I am not able to figure a way out to set context for each individual line.
Did anyone face similar issues before/have any ideas on how to tackle this?
TIA!
Ravi

Hi Ravi,
Please refer below code
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
pageContext.getApplicationModule(webBean).invokeMethod("refreshDetail");
pageContext.setForwardURLToCurrentPage(null,true,null,(byte)0);
public void refreshDetail()
Row[] rows = getFndApplicationVO().getFilteredRows("selection","Y");
if (rows != null)
getFndApplicationVO().setCurrentRow(rows[0]);
Please refer topic "Descriptive Flexfield in a Master/Detail Page" in Jdev guide.

BizTalk Host Application Adapters - Set Client Context Values

http://technet.microsoft.com/en-us/library/bb726925(v=bts.10).aspx
Client Context
The schema provides the node, TIClientContext, allowing context values to be passed. There are several Client Context properties supported by the adapter, listed in Table 7. However, only two are exposed via the messages passed to the adapter as attributes
on the root node - the user’s Host credentials to use for the call and the connection timeout value. The Allow Security Overrides property works in conjunction with Client Context and allows the User and Password to be taken from the TIClientContext node in
the message and used to make the Host program call. In order to access the others, a property schema must be created to add them to the BizTalk Server message context. All of the properties are in the http://microsoft.com/HostApplications/TI/WIP namespace.
Once created, any of these properties can be set via the BizTalk Message Context.
Question:
I am trying to pass LibNameOverride in the Message. I created a property schema and added this promoted property. I am trying to set this value in the Message, but not succesful.
I tried in the below mentioned ways but not successful
<ns0:LibNameOverride>ABCDEFG</ns0:LibNameOverride>
or
<ns0:TIClientContext TIContextKeyword="LibNameOverride" TIContextValue="ABCDEFG" />
Thanks, Pavan MCTS-Microsoft Biztalk Windows Server 2010

Please verify the file version of Microsoft.HostIntegration.Adapters.MsTI.Runtime.dll in the %SNAROOT% folder just to make sure the version.
You might want to try passing PortOverride with an invalid port to see if you get an error in the Application Event log indicating a problem with the connection indicating that the target machine actively refused the connection and it will include the IP
address and the invalid port. It is an Event 102 message.
I passed the following in my sample HIS 2010 Application:
<ns0:BAHA_ELMLink_GetBal__Accounts__GetBalance__Request TIAssemblyVersion="1.0" xmlns:ns0="http://microsoft.com/HostApplications/TI/WIP">
<ns0:GetBalanceInDocument>
<ns0:NAME>Kim Akers</ns0:NAME>
<ns0:ACCNUM>123456</ns0:ACCNUM>
</ns0:GetBalanceInDocument>
<ns0:TIClientContext TIContextKeyword="PortOverride" TIContextValue="7555" />
</ns0:BAHA_ELMLink_GetBal__Accounts__GetBalance__Request>
I don't have an AS/400 sample setup, but this test proved that I could pass a client context property in the input XML to my Send Port.
Also, make sure that you have the "Allowed Advanced Overrides" option in the Send Port set to "Yes" to enable client context override keywords.

Unable to set a new value in an extended property from within a For Each Loop

Setting a new value in an extented property fails when the property is dereferenced within a For Each loop usin the item iterator. However, if you use the First or Last Iterators from the Find Targets activity works fine.
The error message is : "Setting a value for this object type is not allowed"
I believe this is a defect, can you please confirm

Looks like a bug that needs to be reported.
While we are figuring out the issue you can work around the bug.
Add another "Find Targets" inside the loop, and use the ID of the current item in the loop to find the target (again) by ID.
And then use Set Variable on the target that was just found...
I know... Not an ideal workaround, so please open a Severity 4 bug for this.

Adding fields should not affect the settings normally.. is your program fully activated and you have not mentioend any settings explicitly in your code rite?

How to set a attribute value of a sub node binded to a table.. pls respond.

Hi friends,
I have context defined like this.
     Head_node ( table 1)
          Item_node ( table 2, sub node ). ( now this im saving in global internal table).
so now when i hit save button, im passing my internal table (it has col1- sales order no, col2 item details(table type, which can have more than one record) to a FM, to create sales order.
My sales order is getting saved.
But the function module will return some new values (like sales order number, item number etc).
Now i want these values to be updated in my context.
Meaning whenever after that i do get_attribute, i should get these new (sales order no, item no ) also.
I dont know how to set the context values of sub nodes , so im missing these values.
kindly respond back to me..
thanks in advance,
Niraja

Its very simple.
Follow these steps. e.g you want to get the new sales order number. Define a attribute in ur node (or set of attributes in ur case as per reqruirement) say new_so_number.
Check your FM, if its returning new_so_number then it's fine, otherwise you have to change the FM to return the new_so_number or you have to get from db table somehow, which best suites your req.
So once you have new_so_number after calling the FM, say in lv_new_so_number field. Then write this code to set the attribute (change the variables as per your context attributes)
DATA lo_nd_head TYPE REF TO if_wd_context_node.
DATA lo_el_head TYPE REF TO if_wd_context_element.
DATA ls_head TYPE wd_this->element_head.
DATA lv_new_so_number LIKE ls_head-new_so_number.
* navigate from <CONTEXT> to <HEAD> via lead selection
lo_nd_head = wd_context->get_child_node( name = wd_this->wdctx_head ).
* get element via lead selection
lo_el_head = lo_nd_head->get_element( ).
lv_new_so_number = new_so_number. " (You got this as a exporting parameter of FM etc..)
* get single attribute
lo_el_head->set_attribute(
    EXPORTING
      name = `NEW_SO_NUMBER`
      value = lv_new_so_number ).
Hope it works.

Set default values in DFF context programatically in OAF

Hi Guru's,
In our environment, we have one Context sensitive DFF named Party Information having following context:
GUEST
COMPANY
AGENCY
BANK
SUPPLIER
Now the requirement is if Create Customer page renders, this DFF should show only values- GUEST, COMPANY, AGENCY.
We can not disable the context values BANK, SUPPLIER because this DFF is used at many place so we have to use such logic, if Create Customer page renders
it should display only three context programatically.
I can default the one context programatically by below statement-
OADescriptiveFlexBean custinfoDFFBean = (OADescriptiveFlexBean)webBean.findChildRecursive("personFlex");
if (custinfoDFFBean!= null)
custinfoDFFBean.setFlexContextCode(pageContext, "GUEST");
custinfoDFFBean.setContextListRendered(false);
but don't know how to default with three context.
Could anyone please help me on this?
Thanks...
