Use of Separated Variable in Optional Tasks- Null Pointer Exception

Hi,
I'm facing a strange issue with Object Category as 'Separated'. In our Process the main object(objLaunch) is big in size so we have decided to make object category to be separated. Process flow's each and every interactive activity has an optional task which is a Screen Flow. When we have changed the object(objLaunch) category to be 'Separated' we are getting below error when we had accessed the optional task. Please note that we are facing this issue in
PROD environment where as in studio we are not facing this issue. The same object is present in the main process flow as well as in the screenflow(optional task). This object is passed as an input argument to the screenflow from the main process. In the screenflow as well as the main process, we have made the object as separated, though in the screenflow, upon saving and reopening the category still displays as Normal.

Is it not possible to use separated variables in screenflows which will be accessed as optional tasks? The same screenflow forms part of the main process as well. This activity works fine even after the object was made separated. The error is encountered only in the optional task.
Please could you analyze the mentioned issue and let us know the reason for the error.
Anticipating for your response.
Thanks in advance
~Kavitha A

Please could you respond.

Thank you

The task parameters passed into a scheduled job are the parameters defined for the scheduled task definition in the metadata xml and configured in the scheduled job. They are not the data of an individual user as you seem to be trying to get. In a scheduled task I would expect some sort of search for users to operate on.

Problem in getEelementById() method-null pointer exception

Hi All,
I am using DocumentBuilder factory for parsing a xml file.
I am getting the document object and also creating an element in
the root element .And also I am setting the element id for the
element as attiribute .I need to select the element having same ID
using getElementById() method .But it is giving null pointer
exception.
N.B: My parsing file contains dtd declaration and root element.
My sample code look like this;
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db=dbf.newDocumentBuilder();
Document doc=db.parse(ne File("C:/index.xml");
Element root t=doc.getDocumentElement();
root.setAttribute("ID","12345");
Element oElement = doc.createElement(element_name);
oElement.setAttribute("ID",element_id);
Element oEle=doc.getElementById(element_id);
Could anyone please to solve this problem.
Please do favour with me.
Thanks and Regards,
Sreekanth

while creating xml you should mention which attribute is ID attribute using
setIDAttribute() method,
as you are setting "ID" attribute as ID so
after adding Id attribute to the root element
use setIDAttribute("ID",true);
then getElementById will return the element by using ID

ViewDocument.jsp gets null pointer exception when using report token instead of docid for DHTML

The following command gets a null pointer error showing up in Tomcat log:../../viewers/cdz_adv/viewDocument.jsp?sEntry=<%=strEntry%>&lang=en&iDocID=830&ViewType=I&kind=Webiwhere sEntry is a valid report token but works fine if the ViewType is H or id=830 is used instead of sEntry. When the above command is issued the drill columns are displayed correctly but no report is shown and a null pointer exception is encountered.

There is a Consulting Solution called BOInterface that Business Objects Global Services sells and that may help you if you are implementing your own "InfoView".
A description is <a href="http://www.mnsoft.org/bointerface0.0.html">here</a>.
Particularly, see the <a href="http://www.mnsoft.org/pmiv.0.html">Poor Man's InfoView</a> web application.

Null Pointer exception in fullscreen using active rendering

When I create a window use it in fullscreen with active rendering, then close fullscreen, dispose the window and create an identical window wich I use in fullscreen again with active rendering I get a Null pointer exception. The exception happens in the active rendering loop of the second window. Why does this happen and how do I solve it?

Hi,
Please try to pass lookupEvent, LookupCodeColumn values as HashMap object. Try out the following.
com.sun.java.util.collections.HashMap vMyParams = new HashMap();
vMyParams.put("lookupEvent","update");
vMyParams.put("lookupEvent",LookupCode);
pageContext.setForwardURL("OA.jsp?
page=/eis/oracle/apps/xxeis/central/admin/Lookups/webui /EISRSCLookupsCreatePG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
vMyParams , //*Here pass your HashMap object.*
false,
OAWebBeanConstants.ADD_BREAD_CRUMB_YES,
OAWebBeanConstants.IGNORE_MESSAGES);
No need to change the code in other CO as you can still continue with PageContext.getParameter("lookupEvent") etc..
HTH,
Syed.

Af:tree Null Pointer Exception using af:switcher

Hi,
I've implemented a Tree (based on 3 linked SQL Query View Objects). The linked View Objects run ok in the Application Module tester...
I wanted to customize the different levels of the tree so implemented a Switcher component on the Tree as follows (note I've limited the Tree to 2 levels):
<af:tree value="#{bindings.listToDoAppsVO1.treeModel}" summary="ToDo List Tree" var="node"
 id="pt_t8" contentDelivery="lazy"
 initiallyExpanded="true"
 styleClass="AFStretchWidth" inlineStyle="height:inherit;">
 <f:facet name="nodeStamp">
 <af:switcher facetName="#{node.hierType.structureDefName}" id="todo_switcher">
 
 <f:facet name="app_model.listToDoAppsVO">
 
 <af:outputText value="#{node.Appname}" id="ot_app">
 </af:outputText>
 </f:facet>
 <f:facet name="app_model.listToDoTypesVO">
 
 <af:commandImageLink id="pt_ot16"
 text="#{node.Viewtype}"
 icon="/pics/folder-icon.png"
 action="callRouter"
 actionListener="#{backingBeanScope.cognition3coltempBacking.toDoViewGoActionListener}"
 />
 </f:facet>
 </af:switcher>
 </f:facet>
 </af:tree>However, when the page is run the Tree displays correctly initially, but as soon as a link is pressed I get a Null Pointer exception with the following Stack Trace info (top 30 or so lines):

Any ideas please? I'm using JDeveloper 11.1.2.1.0 incidentally...
Thanks.

Hi Frank,
Thanks for your reply. The Partial Submit worked up to a point - the expected navigation to the new view now works when the link is initially pressed. However, if the link is tried again the Null Pointer Exception occurs again.
By the way, the Tree is on a Page Template, where there is another Tree that utilises an af:switcher - and the command link from this tree now fails with the same NPE error. I notice there are warnings for both trees in the Page Template View such that 'Reference "node.hierType" not found'. Not sure how relevant this is given that the Trees both display correctly initially.
The Stack Trace is as follows (can't post the whole thing as it exceeds the 30000 char limit):
<UIXInclude> <_warnUnpoppedContextChanges> ADF_FACES-10021:During the processing of the include component, the context change found did not match the current component. Expected oracle.adf.view.rich.component.fragment.UIXInclude$IncludeContextChange, but got UIXCollection.CollectionComponentChange[Component class: oracle.adf.view.rich.component.rich.data.RichTree, component ID: pt_t8].

Using Back button causes Null Pointer exception

Hi,
I have done some customization by extending the seeded Controller on a Page.I have altered the View query and executed it again dynamically as its not a static query.
There is a functionality called compare which directs the users to a page from the page I have customised the controller.
If the user uses the back button to return to the previous page it is giving a Null Pointer exception.
Also refresh button causes a similar Null Pointer exception on the customised controller page.
can anybody throw some light?
Also is there a way to disable the back and refresh button on the page?

Is the control entering the back button code in process request in your CO? Have you confirmed this by putting some debug comments?It many be that this error might being from the code where you have handled back button.
Put debugging comments and check.

Null Pointer Exception while Retrieving Records using Java API

Hi,
I am using the Class RetrieveLimitedRecords, to retrieve he records from the main table.
While using this class I am getting an error Null Pointer Exception, when there are no records matching the search criteriea.
Could anybody tell me how to ignore this error.
Thanks,
Priya.

Hi,
Thanks for the reply.
There is no any class which automatically handles, so we should handle exceptions individually.
Thanks,
Priya.

Null pointer exception using case clauses

SELECT
CASE 'N'
WHEN 'N' THEN
'N'
ELSE
'Y'
END AS TRAN_TYPE_CODE,
CASE 'N'
WHEN 'N' THEN
'N'
ELSE
'Y'
END AS Narration
FROM DUAL
Run the above query using ODP.NET 10.1 and you get consistently null pointer exception. I also found out that more than 1 case clause in a select statement causes the exception.
Is this a bug? or is my usage wrong? Should I do something special. Any help / guidance is appreciated.

Hi,
I'd guess you might be running into bug 4205389, fixed in 10.1.0.4.02 ODP.
Cheers!

Null pointer exception when using CFCs on Solaris

I am running Apache 2.0.52 and my web root is /htdocs. I have
a multi-server installation of CF 7.0.2 on another partition:
/apps/jrun4. Regular CFM files work fine; however, I receive the
"The system has attempted to use an undefined value..." (null
pointer) error whenever I attempt to use a CFC from within a CFM
file or if I try to use Application.cfc -- Application.cfm works
fine.
For instance...I created two files in /htdocs/test: Test.cfc
and tester.cfm
Test.cfc contains:
<cfcomponent>
<cfset str = "Test">
</cfcomponent>
tester.cfm contains:
<cfset temp = createObject("component", "Test")>
When I run tester.cfm I get the error. I had some success
when I created a mapping in CF Admin called /tester, pointing to
/htdocs/test. I then changed the code in tester.cfm to:
<cfset temp = createObject("component", "tester.Test")>
And it worked! I also tried creating a CFC on the same
partition as the CF install (/apps) and then referencing it in the
tester.cfm code. That works too! However, that's a bandaid solution
and half of one at that. If I try to use Application.cfc anywhere
within /htdocs (web root), I get the null pointer error.
Additionally, I have another server setup identically except
for one difference: the web root is /apps/htdocs (same partition as
CF). Everything works fine on it. Has anyone experienced this
behavior before? Any ideas besides moving /htdocs to /apps/htdocs?
Is this a known issue that the web root must reside on the same
partition as the CF install?

Null pointer exception using ImageIO

Hi all I'm not sure this belongs here or in the applet forum, but if don't belong here I'll move it. Anyway My question is this, I am trying to load an image into an applet before I was just doing this
public static Image getImage(String filename){
 if (applet == null)
 return null; // for now
 else
 return applet.getImage(applet.getDocumentBase(), filename);
 }Since then I've discovered ImageIO and have switched to this
public static BufferedImage getImage(String filename){
 BufferedImage img = null;
 //File image = new File(filename);
 try{
 //img = ImageIO.read(applet.getDocumentBase().getClass().getResource(filename));
 //img = ImageIO.read(image);
 img = ImageIO.read(ImageHandler.getFile(filename));
 }catch(IOException e){
 e.printStackTrace();
 return null;
 return img;Now my problem is that this is giving me a null pointer exception, each of the 3 times I try to load up the img variable I get a NPE and I cannot figure out why. I know the file is where its supposed to be and I know it is not corrupt since it works with the other code. So my question is why am I getting an exception with the second piece of code? Any advice or suggestions are appreciated thanks in advance.

Well that was part of the problem, thanks for that I didn't catch that at first, but now it just created a new exception in that I'm getting a illegal argument exception saying that the input == null. Here is the entire class I should have posted it in the first place sorry
import java.applet.Applet;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.imageio.ImageIO;
public class ImageHandler {
 static Applet applet = null;
 public static void setApplet(Applet applet){
 ImageHandler.applet = applet;
 public static BufferedImage getImage(String filename){
 BufferedImage img = null;
 if(applet == null){
 System.out.println("Applet is null");//for testing
 return null; //for now
 }else{
 try{
 img = ImageIO.read(applet.getDocumentBase().getClass().getResource(filename));
 }catch(IOException e){
 e.printStackTrace();
 return null;
 return img;
}The applet gets set in another class here:
ImageHandler.setApplet(this);so unless I'm missing something (obviously I am or I won't be here lol) the applet is not null here is the errors I get again thanks for the help you've already given anymore is appreciated.

Null pointer Exception in findusersfiltered method

Hi,
I am using Findusersfiltered method to fetch the userkey . But it is throwing a null pointer exception, Findusersfiltered(Unknown source). Please let me know the workaround to solve this issue. Will changing the method to findallusers or any other method to fetch the user key will solve this?
Thanks.

Still getting this error after using findallusers method... Any possible solution?

GetUserRoles in viewobject throws null pointer exception

Hello,
I've set up security for our jsf-adf-bc4j application.
I now want to get the user role in our viewobject.
I use the following code :
SessionImpl session = (SessionImpl) this.getDBTransaction().getSession();
String[] roles = session.getUserRoles();
for (String role : roles){
System.out.println(role);
This throws a null pointer exception at the"System.out.println(role);" line .
The user has a role (I can read the role in the viewcontroller project)
In the view object i can also get the session.getUserPrincipalName(). This works fine.
Can anybody help me with this problem ?

You define a local ArrayList here:public MonthlySchedule()
ArrayList<Request> monthlyschedule= new ArrayList<Request>() ;
}Just instanciate the instance variable.
