ADF: How to get the attributes' values of one single row from a table?

Currently I have a table with 3 attributes, suppose A,B and C respectively. And I've added an selectionListener to this table. That means when I select one single row of this table, I wish to get the respective value of A, B and C for that particular row. How do I achieve this?
suppose the method is like:
public void selectionRow(SelectionEvent se) { //se is the mouse selection event
.......??? //what should I do to get the values of A\B\C for one single row?

Hi
Assuming you are using Jdev 11g.
Try with this
public void selectionRow(SelectionEvent se) {
String val = getManagedBeanValue("bindings.AttributeName.inputValue");
public static Object getManagedBeanValue(String beanName) {
StringBuffer buff = new StringBuffer("#{");
buff.append(beanName);
buff.append("}");
return resolveExpression(buff.toString());
public static Object resolveExpression(String expression) {
FacesContext facesContext = getFacesContext();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, expression,
Object.class);
return valueExp.getValue(elContext);

Here is attribute identifier operator from FB Help:
@ attribute identifier Operator
Usage myXML.@attributeName
Identifies attributes of an XML or XMLList object. For
example, myXML.@id identifies attributes named id for the myXML XML
object. You can also use the following syntax to access attributes:
myXML.attribute("id"), myXML["@id"], and myXML.@["id"]. The syntax
myXML.@id is recommended. To return an XMLList object of all
attribute names, use @*. To return an attribute with a name that
matches an ActionScript reserved word, use the attribute() method
instead of the @ operator.
Operands attributeName:* — The name of the attribute.
Example
How to use examples
The first example shows how to use the @ (at sign) operator
to identify an attribute of an element:
var myXML:XML =
<item id = "42">
<catalogName>Presta tube</catalogName>
<price>3.99</price>
</item>;
trace(myXML.@id); // 42The next example returns all attribute
names:
var xml:XML =<example id='123' color='blue'/>
var xml2:XMLList = xml.@*;
trace(xml2 is XMLList); // true
trace(xml2.length()); // 2
for (var i:int = 0; i < xml2.length(); i++)
trace(typeof(xml2
)); // xml
trace(xml2.nodeKind()); // attribute
trace(xml2
.name()); // id and color
} The next example returns an attribute with a name that
matches a reserved word in ActionScript. You cannot use the syntax
xml.@class (since class is a reserved word in ActionScript). You
need to use the syntax xml.attribute("class"):
var xml:XML = <example class='123'/>
trace(xml.attribute("class"));

How to copy the attribute values of one instance into another instance.

Say I have 3 instances and two attributes name ,id.
inst1 : id:1 ,name:abc
inst2: id:2 ,name:bcd
inst3: id:3 ,name:efg
now I want
inst: id:1 ,name:abc
bcd
efg
i.e is need to abort instance inst2 & inst3 before that copy the names bcd & efg to inst1.
Please let me know how to do this its very urgent.

Hi,
The tricky part of this is to provide your third instance a way to find the other two instances. Finding instances in a process is a bit like finding rows in a database. When doing a SELECT statement in a database, you have a primary key that will guarantee you that you'll only retrieve one row. In Oracle BPM there are a couple ways to do this. One way is to use the instance's id (the predefined variable id.id) to search for the two instances. Another is to use a "correlation" to find the instances.
This example assumes you'd like to look at instances based on a search filter. This filter assumes that you have a customerId variable that both of the instances share. It only returns those instances currently inside the process (the SearchScope logic below being set to "StatusScope.ONLY_INPROCESS" in the logic below). The only incoming variable it needs is the "customerId" variable that has already been set to some value in the other instance. Note that this uses the Fuego.Papi.ClientBusinessProcess object. This logic creates a search filter and only returns instances that meet a certain criteria (the two instances in the process). Once you get the instance, the "getVar()" method retrieves the "name" instance variable. This assumes that you have an instance variable "customerNames" defined as a String array that you are using to store the names retrieved from the two instances. The "abort()" method aborts the two instances it finds in the search.
cbp as ClientBusinessProcess = ClientBusinessProcess()
connectTo(cbp, processId : "/NameOfYourProcessHere")
instF as InstanceFilter = InstanceFilter()
create(instF, processService : cbp.processService, viewId : "TypeSearch")
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL,
                              statusScope : StatusScope.ONLY_INPROCESS)
logMessage "Customer Id is: " + customerId using severity = DEBUG
addAttributeTo(instF, variable : "customerId",
                          comparator : IS, value : customerId)
for each inst in getInstancesByFilter(cbp, filter : instF) do
   // get the value of the order's amount for the instance
    instanceVarValue as Object = getVar(inst, var : "name")
    customerNames[] = String(instanceVarValue)
    logMessage "Customer name is: " + String(instanceVarValue)
             using severity = DEBUG
    // aborts the instance in the process
    inst.abort()
endHope this helps,
Dan

Hi,
It can be done using xmlagg function.
For Example :
Table Data..
DEPTNO     ENAME
20     WARD Tree
23     Shank
30     BLAKE
10     MILLER
30     MARTIN
10     CLARK
20     SCOTT
30     TURNER
20     ADAMS
30     JAMES
20     FORD
30     BLAKE
Query:
SELECT deptno,
RTRIM (XMLAGG (XMLELEMENT (e, ename || ',')).EXTRACT ('//text()'),
) NAME
FROM emp
GROUP BY deptno;
Output :
DEPTNO     NAME
10     MILLER,CLARK

How to get the execution time of a Discoverer Report from qpp_stats table

Hello
by reading some threads on this forum I became aware of the information stored in eul5_qpp_stats table. I would like to know if I can use this table to determine the execution time of a worksheet. In particular it looks like the field qs_act_elap_time stores the actual elapsed time of each execution of specific worksheet: am I correct? If so, how is this value computed? What's the unit of measure? I assume it's seconds, but then I've seen that sometimes I get numbers with decimals.
For example I ran a worksheet and it took more than an hour to run, and the value I get in the qs_act_elap_time column is 2218.313.
Assuming the unit of measure was seconds than it would mean approx 37 mins. Is that the actual execution time of the query on the database? I guess the actual execution time on my Discoverer client was longer since some calculations were performed at the client level and not on the database.
I would really appreciate if you could shed some light on this topic.
Thanks and regards
Giovanni

Thanks a lot Rod for your prompt reply.
I agree with you about the accuracy of the data. Are you aware of any other way to track the execution times of Discoverer reports?
Thanks
Giovanni

How to refer a column value of a single row in conditional column display?

Hello,
does anybody have an idea, how i can refer a column value of a single row in conditional display of a column?
So my idea is, that a report has a column, which value is only displayed, when another column value of this row has a specific value.
I want to solve this problem with condition type: PL/SQL Function Body returning a boolean.
But I do not know how to refer the column value of each single row!
Thank you,
Tim

Here's a solution that, to me, seems easier to implement but, that's, of course, in the eye of the implementer.
Rather than using APEX to generate a link column for you, actually create the link as part of your SQL.
select '<a href="f?p=102:3:491847682940364::::P3_CONTACT_ID:' || CONTACT_ID || "><img src="/i/themes/theme_1/ed-item.gif" alt="Edit"></a>' CONTACT_LINK, ...
etc.
Test this out. You'll see that it works just like making a column a link using the column attributes.
Next, we'll change the SQL to use a DECODE statement to either display the link or nothing depending on what your criteria is. For example, let's assume you only want a link for active contacts.
select Decode( CONTACT_STATUS, 'A', '<a href="f?p=102:3:491847682940364::::P3_CONTACT_ID:' || CONTACT_ID || "><img src="/i/themes/theme_1/ed-item.gif" alt="Edit"></a>', NULL ) CONTACT_LINK, ...
etc.
This will not display the link in any rows in which the CONTACT_STATUS is not active, i.e. "A"

In Jsp TagLib how can I get the Attribute value (like JavaBean) in jsp

Dear Friends,
TagLib how can I get the Attribute value (like JavaBean) in jsp .
I do this thing.
public void setPageContext(PageContext p) {
          pc = p;
pc.setAttribute("id", new String("1") );
          pc.setAttribute("first_name",new String("Siddharth")); //,pc.SESSION_SCOPE);
          pc.setAttribute("last_name", new String("singh"));
but in Jsp
<td>
<%=pageContext.getAttribute("first_name"); %>
cause null is returing.
Pls HELP me
with regards
Siddharth Singh

First, there is no need to pass in the page context to the tag. It already is present. How you get to it depends on what type of tag:
Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/SimpleTagSupport.html]SimpleTagSupport
public class MyTag extends SimpleTagSupport
public void doTag()
    PageContext pc = (PageContext)getJspContext();
    pc.setAttribute("first_name", "Siddharth");
    pc.setAttribute("last_name", "Singh");
    pc.setAttribute("id", "1");
}Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/TagSupport.html]TagSupport or it's subclass [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/BodyTagSupport.html]BodyTagSupport the page context is aleady declared as an implicit object:
public class MyTag extends TagSupport
public void doStartTag()
    pageContext.setAttribute("first_name", "Siddharth");
    pageContext.setAttribute("last_name", "Singh");
    pageContext.setAttribute("id", "1");
}In each case, this sort of thing should work:
<mytags:MyTag />
<%= pageContext.getAttribute("first_name") %>I

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 the selectOneRadio value in javascript

Hi,
I want the selectOneRadio value in javascript. Can anyone give us a solution how to get the selectOneRadio value to javascript from jspx page.
Thanks,
Eswari

Hi,
I assume you are talking about JDeveloper 10.1.3 in where there is no JavaScript API ADF Faces.Here you will have to use document.getElementById() to access the radio button component (which is a list component). You can look at the generated HTML for how the component and its ID look like.
However, what is the usecase that you cannot handle in native JSF ?

Runtime error to get the attribute value of an element

mydoc.xml
=========
<?xml version = "1.0"?>
<persons>
     <person name="Joe" age="22" />
</persons>
In mydox.xml, I want to get the attribute values of element person. Of course,
in the actual XML file, it is more complicated.
However, I get the following run-time error,

any ideas? Thanks!!

[url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/NullPointerException.html]java.lang.NullPointerException
Thrown when an application attempts to use null in a case where an object is required. These include:
Calling the instance method of a null object.
Accessing or modifying the field of a null object.
Taking the length of null as if it were an array.
Accessing or modifying the slots of null as if it were an array.
Throwing null as if it were a Throwable value.
You know what line it happens on, so you know which of these cases applies. So you know that variable "element" is null at that point. How could it come to be null? You assign to it only once, two lines above. How could that assignment be null? Check the documentation for [url http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html#getElementById(java.lang.String)]org.w3c.dom.Document.getElementById().
Repeat every time you get one of those exceptions.
