How to get the previous value of Potential Revenue, as Number

PRE('<Revenue>') will return the previous value of the Potential Revenue (in Opportunity object), as a string.
However, i need to manipulate the returned value as number in order to evaluate if the previous value is less a certain amount.
PRE('<Revenue>')*.3204<50000
The expression about, is meant to convernt the value to a different currency, and evaluate if its less than 50000.
Is there any way I can be able to achive this?
appreciate you response! :)

How to get the previous value of a field before saving the record

Hi All,
I have a requirement like, listing out the modified field values with their previous value and new value using integration events or any method.
For Ex: If i modify the customer name from "Jack" to "Amith" in the record.
Then i have a requirement to display the message like : CustomerName has changed from "Jack" to "Amith"
Please post your help notes on this.It's Urgent.
Thanks & Regards
Amith

Hello Amith,
How does a user perform the modification? Do you already have access to the existing value when the user makes the update? How are you identifying the record to be updated within CRMOD and what method are you using to perform the update?
Thanks,
Sean

How to get the return values from a web page

Hi all :
how to get the return values from a web page ? I mean how pass values betwen webflow and web page ?
thank you very much
Edited by: jingying Sony on Apr 15, 2010 6:15 AM
Edited by: jingying Sony on Apr 15, 2010 6:18 AM

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

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 attribute value of an XML file??

How to get the attribute value of an XML file??
For example, how to get name and age attributes?
<student name="Joe" age="20" />

What are you using to read the XML file??
On the assumption of JDOM - www.jdom.org. Something along the lines of:SAXBuilder builder = new SAXBuilder(true);
Document doc = builder.build(filename);
Element root = doc.getRootElement();
List children = root.getChildren();
Element thisElement = (Element)children.get(n);
String name = thisElement.getAttributeValue("name")
try
int age = Integer.parseInt(thisElement.getAttributeValue("age"));
catch (Exception ex)
throw new InvalidElementException("Expected an int.....");

How to get the previous state of my data after issuing coomit method

How to get the previous state of some date after issuing commit method in entity bean (It should not use any offline storage )

>
Is there any way to get the state apart from using
offline storage ?As I said the caller keeps a copy in memory.
Naturally if it is no longer in memory then that is a problem.
>
and also what do you mean by auditlog?
You keep track of every change to the database by keeping the old data. There are three ways:
1. Each table has a version number/delete flag for each record. A record is never updated nor deleted. Instead a new record is created with a new version number and with the new data.
2. Each table has a duplicate table which has all of the same columns. When the first table is modified the old data is moved to the duplicate table.
3. A single table is used which has columns for 'table', 'field', 'data' and 'activity' (update, delete). When a change is made in any table then this table is updated. This is generally of limited useability due to the difficulty in recovering the data.
All of the above can have a user id, timestamp, and/or additional information which is relevant to the data being changed.
Note that ALL of this is persisted storage.
I am not sure what this really has to do with "offline storage" unless you are using that term to refer to backed up data which is not readily available.

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 ?

How to get the node value of payload

Hi
The null is returned when I use the following code to get the User_ID element in the payload, but there are values in the User_ID element of the payload
Task task_test = wfSvcClient.getTaskQueryService().getTaskDetailsById(wfCtx, taskId);
System.out.println("the payload value is " + task_test.getPayloadAsElement().getElementsByTagName("User_ID").item(0).getNodeValue());
How to get the node value of payload ? any suggestion?
Thanks
Jayson

Hi Jayson,
Try:
System.out.println("the payload value is " + task_test.getPayloadAsElement().getElementsByTagName("User_ID").item(0).getFirstChild().getNodeValue());
So add the getFirstChild() call in between.
If this works, maybe consider using JAXB to marshall the payload details to POJO's. This will make reading the payload details much easier.

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.

JList and ListSelectionEvent : How to get the deselected Value

Hi,
All of you know:
The ListSelectionEvent occurs two times:
1.) An Enty is deselected
2.) The new Entry is selected.
I wanted to use the first occurence to save some data from the deselected Entry (from an Editor to a Record), and the second occurence to load the Data from the selected Entry to an Editor.
(Until now, i use a additional lastSelectedIndex Property for that, but i dont find this very elegant.)
Now i found that the index is allways the same. The output of the code is:
Event 0 Index:2
Event 1 Index:2
Has anybody an idea how to get the deselected Value ??
public void valueChanged(javax.swing.event.ListSelectionEvent listSelectionEvent) {
JList list=(JList)listSelectionEvent.getSource();
int selectedIndex = list.getSelectedIndex();
System.out.println("Event " + count + " Index:" + selectedIndex);
count = count+1;
// Drop one oft them...
if (listSelectionEvent.getValueIsAdjusting()) return;
count=0;
}

Thanks, but thats not exactly what i wanted.
I have a selectedIndex: 5
Now i select a other item in the List, say Index: 2.
The ListSelection-Event occurs two times:
My understand was:
The first occures, because an Item was deselected: index should be:5
The second occures, because an Item was selected : index should be:2
Is my thinking wrong?
The code above allways gets only Index 2.
How can i get the Index/Value 5,

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"));
