How to get current db value in backing bean

Hi,
I'm using jdeveloper 11.1.2.3.0
I would like to know how could I access the old value of an attribute in backing bean.
I know I can get it in the EntityImpl level with getPostedAttribute function,
but as I see I don't have permission to access this function in the ViewImpl.
I get this error:
Error(151,33): getPostedAttribute(int) has protected access in oracle.jbo.server.EntityImpl.
Could you help?
What is the correct way to get the current value on db in backing bean?
Thanks a lot!

You can add a transient attribute to the Entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

How to get Current Row values in Af:ForEach

Hi,
We have a requirement to conditionally Display/Hide CommandLink item in af:forEach Loop.
<af:forEach items="#{bindings.RegionalAreaPVO.rangeSet}" var="parent">
<af:spacer height="10" id="s1"/>
<af:commandLink inlineStyle="font-weight:bold;" text="#{parent.ItemName}" partialSubmit="true" actionListener="#{backingBeanScope.RegionalAreaBean.launchTaskflow}" id="cl1" rendered="*#{backingBeanScope.XXWFCRegionalAreaBean.modelEligibleflag eq true}*">
<af:setActionListener from="#{parent.Code}" to="#{parentNode}"/>
</af:commandLink>
</af:forEach>
I have added a Cutom Managed Bean Class and Returning boolean value to Control Render property which is working. But now i want to add business Logic based on 'parent.ItemName' or 'parentNode' Values in the bean method to return proper Boolean value.
But i am unable to get the Current Iteration values in the bean method.
I am using below EL expressions to get the values. But no luck.
String nameel = (String)ADFUtil.evaluateEL("#{bindings.parent.ItemName}");
String codeel = (String)ADFUtil.evaluateEL("#{parent.Code}");
String nodeEl = (String)ADFUtil.evaluateEL("#{parentNode}");
Also, i have tried getting the Row object like below but i am getting the First row details always. My intention is to get Current row values and use them for Business logic.
ViewRowImpl row =
(ViewRowImpl)ADFUtil.evaluateEL("#{bindings." + VoName +
"Iterator.currentRow}");
String code = (String)row.getAttribute("Code");
Any help is highly appreciated.
Thanks
Kaja

Hi Sascha,
I have tried that. But in my case the functional logic behind the Rendering is based on more complex logic. Hence i am trying to add a method to return a boolean in Render property of the Link.
But the real problem for me is, in the Managed bean method i am not finding a way to get the Current Iteration index. If i can get the Current iteration index, i can get the Corresponding Component ID of Command link (In the forEach Loop Component Id's are getting generated Dynamically based on Iteration Index), i can use that and add additional logic and derive true/false to return.
Any inputs?
Thanks

How to get current row value from table when press the submit button

Hi,
I want to get the current row value of SuccessionPlanId which is one of the column in a advanced table.
I created one button (created using personalization, action fired thru CO)in the table as column, so each row having one button, if i press the first row's button means then i want to fetch the first row's SuccessionPlanId and if it is 3rd means then i want to get the value of third row's value.
How to do it in controller extension?
Please reply soon, its urgent.
Thanks in advance,
SAN

Pratap,
Yes, I tried with 'delete' button which is seeded one.
For this, our code using row reference is working too fine. it throws exact SuccessionPlanId value of corresponding row.
I created MessageStyledText, but here i need to give text value right, then only it 'll appear in the page.
Instead i created one image and fired explicitly from the controller processRequest method.
But the same problem remains..
here my code:
public void processRequest(OAPageContext pageContext, OAWebBean webBean){
super.processRequest(pageContext, webBean);
OAButtonBean oabb = (OAButtonBean)webBean.findChildRecursive("XXSubmit");
FireAction action = new FireAction("XXSubmit");
oabb.setAttributeValue(UIConstants.PRIMARY_CLIENT_ACTION_ATTR, action);
OAImageBean oaib=(OAImageBean)webBean.findChildRecursive("XXSubmitImage");
oaib.setFireActionForSubmit("XXSubmitImage", null, null, true);
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean){
if("XXSubmitImage".equals(pageContext.getParameter("event"))){
String succIdI="";
String rowRefI = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
if(rowRefI != null && !("".equalsIgnoreCase(rowRefI ))){
PerSuccPlanSearchVORowImpl rowI = (PerSuccPlanSearchVORowImpl)oaam.findRowByRef(rowRefI);
if(rowI != null)
succIdI=rowI.getAttribute("SuccessionPlanId").toString();
}else{
throw new OAException("Row is null");
throw new OAException(succIdI, OAException.INFORMATION);
}else{
super.processFormRequest(pageContext, webBean);
If i run the page using this controller, it throws exception without any value, because for 'succIdI' i initialized without any string.
Can you please suggest me how to solve?

Timo,
I am new to Jdevloper. I will explain the issue in detail.
Version: Oracle 9i Jdeveloper
I have a query page with multiple records. when I perform action , I need to pass 2 parameters from query screen to my actual page.
1 parameter is Login person Id,. Now the issue is with getting current value for 2nd paramenter. 2nd Parameter will be changed depends upon record i am choosing in my query page: column is : Information Name.
when I use getcurrentrow , I am getting null pointer exception.
My controller class when I click action button :
if("action".equals(pageContext.getParameter(EVENT_PARAM)) )
Serializable methodParams[] = {pageContext.getEmployeeId()+""};
applicationModule.invokeMethod("executeSearchVO1",methodParams);
{color:#993300}
// Here I need to get InformationName value based on the record I am choosing{color}
HashMap hashMap = new HashMap(2);
hashMap.put("XXHRPersonId", pageContext.getParameter("XXHRPersonId"));
// hashMap.put("InformationName", methodParams);
pageContext.forwardImmediately(
"OA.jsp?page=/xxhr/oracle/apps/xxhr/selfservice/personalaction/webui/XXHRPersonalActionPG",

null,
hashMap,
true, // Retain AM

// Row row = personalActionSearchVO.first();
Row row = personalActionSearchVO.getCurrentRow();
System.out.println("Informaton Name "+row.getAttribute("InformationName");
In this , If i initialzie with Row row = personalActionSearchVO.first();I am able to get value for my column Information Name.
whereas, if I use directly Row row = personalActionSearchVO.getCurrentRow();, i am getting null pointer exception.
Pl. let me know how to get current row value for Information Name.
Looking for the reply at the earliest.

How to get the current JSF phase in backing bean?

I am using phasetracker to trace it also.I want to know whether it is it render response phase. I know FacesContext.getCurrentInstance().getRenderResponse() work for normal jsf component but it will not work for qiupukit datatable. FacesContext.getCurrentInstance().getRenderResponse() will not return true in the following phase. Why?

How to get readonly text field value in backing bean?

Below is my code in JSF.
<h:inputText id="prodLine" value="#{fbackingBean.value}" required="true" styleClass="readOnlyField" readonly="true"/>
This is a readonly field, and the value will been pass in by a pop up window. after the value had been passed in, i try to store the data which i had selected, but the value in readonly field (which show in above) return a null value.
May i noe how can i get the readonly field value in backing bean? thanks!

Why not keep track of the value in the backing bean? If it's a read only value set from a backing bean it should be simple to retrieve from a backing bean.
I'm new to JSF, but one thing that I have figured out is to try to put everything in the backing beans possible and to do as little as possible within the JFS web page components.

How to get the selected value in SelectOneMenu in backing bean

Hello all,
I need your help. I want to have 2 select menus with the second menu's items list are populated based on the selection in the first menu. I don't know how to get the selected value in the backing bean so that I can based on that select menu to populate the second menu's item list. Basically I need to access to the UI Component of the first select Menu and retrieve its selected value.
Could you help me out?
Thank you very much in advance,
Lngo

Hi Lingo,
There r two ways of getting the values into the list. First one is hardcoding the values and the second one is use the list and get the values into the list by firing a query in the database.
Inorder to display the values in the second menu based on the first onces selection we need to add an attribute to the first selectonemenu known as valueChangeListener and we need to sumit the page.
Here is the sample code
<h:selectOneMenu id="catalogue"
                              binding="#{urbean.catalogue}" onchange="submit()"
                              valueChangeListener="#{urbean.categoryValueChange}"
                              <f:selectItem itemLabel="Select Catalogue" itemValue="" />
                              <f:selectItems value="#{urbean.catalogueList}" />
</h:selectOneMenu>
<h:selectOneMenu id="category"
                              binding="#{urbean.category}">     <f:selectItem itemLabel="Select Category" itemValue="" />
                              <f:selectItems value="#{urbean.categoryList}" />
                              <                         </h:selectOneMenu>
now in method called by valuechangelistener we need to write the similar code
public void categoryValueChange(ValueChangeEvent event) {
String rfnum = (String) event.getNewValue();
List categoryList = new ArrayList();
List tempList = new TablenameDAO().getActiveCatByCatalogueID(rfnum);
          for (int i = 0; i < tempList.size(); i++) {
               Tablename tablename = (Tablename ) tempList.get(i);
               String value = "" + tablename .getrfnum();
String label = tablename .getname();
     if (label == null) {
               label = "";
               SelectItem item = new SelectItem(value, label);
               categoryList.add(item);
          bean.setCategoryList(categoryList);
///getActiveCatByCatalogueID (rfnum) should bring the records which r based on the rfnum
if u follow this process i am damsure that u will get the values in to the secondlist based upon the first list
Thanks & Regards

How to get value in backing bean from application module

Hi all.. I'm new in jdeveloper and adf..
I need to use value from backing bean and use that value in application module.
But I don't know how to get it.
Do you a have any solution?

suppose you have myMethod(String argumentName1,String argumentName2) in your Application Module
then to access a method binding from a managed bean, use the following code,
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
OperationBinding operationBinding =
       bindings.getOperationBinding("name_of_method_binding");
//Here you can pass the parameters value to the AM method
operationBinding.getParamsMap().put("argumentName1",value1);
operationBinding.getParamsMap().put("argumentName2",value2);
//invoke method
operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
     //check errors
     List errors = operationBinding.getErrors();
//optional
Object methodReturnValue = operationBinding.getResult();

How to get the kerning value and set it to back use script?

hi,guys
I come back again.
I encountered a kerning problem.
how to get the kerning value and set it to back use script?
Thanks very much!

For both cases, the filename can be found on the FILE.ReceivedFileName Context Property. You can access this Property in a Pipeline Component or Orchestration and take any action you want, such as apply to a database.
The value is accessed by: MyReceivedMessage(FILE.ReceivedFileName)
In the case of a duplicate EDI Interchange, you would use the Failed Message Routing feature to capture the error message with either an Orchestration or Send Port.

How to get current rowindex of clicked object in cr2008 preview control

repReport.Rows(RowIndex).Item(ColumnIndex)
how to get current rowindex ?
Thanks
Sanjiv Sharma

Only way I can think of is to use the rowset controller from the InProc RAS SDK. Here is a snippet of a sample code on how to:
//Load the report
if (clientDoc != null) {
//create metadata structure
RowsetMetaData rowSetMetaData = new RowsetMetaData(); rowSetMetaData.setDataFields
(clientDoc.getDataDefinition().getResultFields());
       Fields fields = rowSetMetaData.getDataFields();
       String colName,colTypeName;
       int colType, len;
       Field field;
       HashMap colNames = new HashMap();
       HashMap colTypes = new HashMap();
       for (int i = 0; i < fields.size(); i++) {
               field = (Field) fields.get(i);
               colName =field.getDisplayName(FieldDisplayNameType.description, Locale
.ENGLISH);
               colNames.put("COL"+i,colName);
       colType = getColTypeFromVariant(field.getType().toVariantTypeString());
       len=field.getLength();
              //Placeholder
        //add column metadata to data structure or XML
        Object colValue;
        int rowCount=0;
        if (getMaxRows() != 0) {
               RowsetCursor rowsetCursor = clientDoc.getRowsetController(). createCursor
(null, rowSetMetaData);
              //Setting the batch size to make sure that you get back all the
              //rows by setting the batch size.
                    clientDoc.getRowsetController().setRowsetBatchSize (rowsetCursor
.getRowset().getTotalRecordCount());
           //Getting the Results back starting from the first row
           RowsetCursor resultCursor = clientDoc.getRowsetController(). createCursor(null,
rowSetMetaData);
           resultCursor.moveTo(0);
              while (!resultCursor.isEOF()) {
                  for (int i = 0; i < fields.size(); i++) {
                           colName=(String)colNames.get("COL"+i);
                           colTypeName=(String)colTypes.get("COL"+i);
colValue=record.getValue(i);
                            //Placeholder

T_tab1------- zzz------------Y
T_tab2------- xyz-----------YI am creating a tab condition for T_tab1. If user has priviliges, user will see the tab, else no.
I have a PL/SQL function in the database which accepts tab_name and username and return 'T' or 'F' based on table rows.
I have written following statement in 'T_tab1' tab expression(PL/SQL Function body return a Boolean):
IF get_tab_access('xyz', v('TAB_NAME')) = 'T' THEN
RETURN 'T'
ELSE
RETURN 'F'
END IF;During my testing6 I found that v('TAB_NAME') is not passing value to the function.
Can someone tell me how to pass current tab value to the fuction?

How to get current assigned participant id?

Hi mates,
This might be a basic questions, but useful for me :)
How to get current assigned participant id from screenflow? Or How to pass it as an argument from interactive activity?
Below is what I tried.
Participant.id or Instance.participant.id - returns login user id
Thanks

Hi,
Please correct me if I understood wrong.
You want to know whether an instance is assigned or not and if assigned then you want to fetch the assigned participant id.
If this is your requirement then please find the code below and make the necessary changes into it.
Write the following code in screen flow automatic activity but before that you need to pass the instanceid as argument to the screen flow.
In the process as well as screen flow layer make an instance variable instanceid as Int.
Then make an argument variable instanceidArg as Int in both the screenflow and process layer and map accordingly so that it will take the instanceid from process layer to the screen flow layer.
Assign instanceid = id.number; in process layer automatic activity but before the global interactive activity where you have maped the screen flow.
Write the following code in screen flow automatic activity.
logMessage("============= instanceid ==============" + instanceid); //instanceid is the id of the instance that you have passed from process layer.
ProcessService ps;
InstanceFilter instF = InstanceFilter();
ps.connectTo(url : Fuego.Server.directoryURL, user : "<userid>", password : "<password>"); //In studio the userid and password will be same
logMessage("Connected");
instF.create(processService : ps);
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
//<ProessId Name> is the id of the process where you want to know the assighed participant id
instF.addAttributeTo(variable : VarDefinition.processid, comparator : Comparison.CONTAINS, value : "/" + "<ProessId>");
instF.addAttributeTo(variable : VarDefinition.INSTANCE_NUMBER, comparator : Comparison.IS, value : Int(instanceid));
Fuego.Papi.Instance[] instances = getInstancesByFilter(ps, filter : instF);
foreach (instance in instances) {
logMessage("Assigned ?: " + instance.participantId.empty);
logMessage("instance.participantId: " + instance.participantId);
ps.disconnectFrom();
