Null pointer Exception in NodeCMIModelClassWrapper.java:46

Hi all,
I created a test program to see how OVS works.
I did all the steps as explained in document "Web Dynpro Valuehelp Using Object Value Selector.pdf" but instead of use BAPI_FLIGHT_GETLIST, I change to BAPI_FLCUST_GETLIST and I did all the changes as required, because now the OVS is implemented for field CustomerID instead of Airlineid.
The application starts without problems but when I click the icon to call the OVS, it raises exception:
java.lang.NullPointerException
at com.sap.tc.webdynpro.progmodel.valuehelp.NodeCMIModelClassWrapper.<init>(NodeCMIModelClassWrapper.java:46)
at com.sap.tc.webdynpro.progmodel.valuehelp.NodeSingletonCMIModelClassWrapper.<init>(NodeSingletonCMIModelClassWrapper.java:35)
Unfortunatelly it is a lot of code to insert here.
Does anyone have any idea?
Regards,
Mauricio

I found the problem, it was in the input node cadinality

Null pointer exception while inserting a new row in ADF with jdev

Hi,
In ADF, I have retrieved some user information from LDAP server and I want to insert those values in to my table. But when I do this, I am getting a null pointer exception when I get the view object (ViewObject vo=getCRUIP002_1();). I am not sure why this happens.
Here is my code. It is urgent.
and please some one help me in fixing the issue.
ViewObject vo=getCRUIP002_1();
vo.clearCache();
vo.setMaxFetchSize(0);
vo.executeQuery();
Row newRow=vo.createRow();
vo.insertRow(newRow);
SearchResult res = (SearchResult)results.next();
Attributes attrs = res.getAttributes();
// Row newRow = vo.getCurrentRow();
newRow.setAttribute("LOGINNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("PASSWORDVALUE","x");
newRow.setAttribute("FIRSTNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("LASTNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("EMAIL",(Object)attrs.get("mail").get().toString());
Thanks,
Priya.S

assuming ur jdev version is 10.1.2
ViewObject vo=getCRUIP002_1();i dont think ur getting the view object hence null pointer expception.
ViewObject vo = findViewObject("MyView1");
if u r in the object class then first get the root application module and then access the View obejct from there.
In ADF if u assign a null value, u will always get the null pointer exception coz of java. Run the app in debug mode and check the values step by step, by the way there is not exception handling in ur code either, Do u know how to debug in Jdev ?

Java Null Pointer Exception while Importing a Table to IS

Hello All,
I am trying to import a table into IS and receiving a JAVA Null Pointer Exception. The table is in a Teradata database and I am able to import other tables belonging to the same schema.I get the Java error only while trying to import this one particular table. The DBA has confirmed that the table belongs to the schema/owner I am using. In any case, it seems more of a application error than a database level error. Can anyone provide any insight? Thank you in advance.

hi Keerthi,
thank you.
i tried with below code but still unsuccesfully
+ oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
anyway i'm not able to reach your suggested if statement because execution stops before.
Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
page doesn't give error and saves data.
any suggestion appreciated,
thanx,
N

Java Null Pointer Exception- Business Validation In AM

Hi, I have been tried cracking this validation issue, tried several combinations. But does not work and throw java null pointer exception. I would appreciate if somebody can point where I am going wrong on the code. Thanks ahead.
Below is the issue:-
I have a page with PO (blanket purchase order) header info, and a PO line info with additional empty columns (related to Blanket Release). When the user fills in one of the columns (release amount, rls_amt_i), then I need to validate this against remaining blanket amount ie.{ PO_amt - (po_rls_amt1 + po_rls_amt2+..)}. If rls_amt_i is <= remaining amount, then the release needs to get created, otherwise shouldn't. I know, this is a pretty normal requirement. Please check my code to see where I could be wrong.
ReleaseCO (in PFR):-
if (pageContext.getParameter("Apply") != null)
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)am.findViewObject("CxPoReleaseVO1");
Number poHeaderId = (Number)vo.getCurrentRow().getAttribute("PoHeaderId");
String poNumber = (String)vo.getCurrentRow().getAttribute("PoNumber");
OAViewObject linesVO = (OAViewObject)am.findViewObject("CxPoReleaseLinesVO1");
Number lineAmt = (Number)linesVO.getCurrentRow().getAttribute("Amount");
Serializable [] params = {poHeaderId.toString(), poNumber, lineAmt.toString()};
am.invokeMethod("apply", params);
ReleaseAM:-
public void apply(String poheaderId, String poNumber, String lineAmt)
Number blanketAmt, totalreleasesAmt, lineRlsAmt;
try
{ lineRlsAmt = new Number(lineAmt.trim());}
catch(Exception e) { throw new OAException("AK", "FWK_TBX_INVALID_EMP_NUMBER"); }
totalreleasesAmt = getReleasesAmt(poheaderId);
blanketAmt = getBlanketAmt(poNumber);
if ((lineRlsAmt.intValue() - (blanketAmt.intValue()-totalreleasesAmt.intValue())) <= 0)
getTransaction().commit();
approve();
throw new OAException("The amount is less than the remaining release amt", OAException.INFORMATION);
} // end apply()
public Number getReleasesAmt (String poHeaderId)
CxTotalReleaseQuantityVVOImpl totalreleaseqtyVO = getCxTotalReleaseQuantityVVO1(); //vo to get TotalReleased Amount
Number poHeadNum = null;
Number totalqty;
try { poHeadNum = new Number(poHeaderId); }
catch (Exception e) { throw OAException.wrapperException(e); }
totalreleaseqtyVO.initQuery(poHeadNum);
CxTotalReleaseQuantityVVORowImpl row = null;
row = (CxTotalReleaseQuantityVVORowImpl)totalreleaseqtyVO.getCurrentRow();
try { totalqty = (Number)row.getQuantityReleased();}
catch (Exception e) { throw new OAException(e.getMessage()); }
if(totalqty != null)
{ return totalqty; }
else
{ throw new OAException ("exception occurred", OAException.ERROR); }
public Number getBlanketAmt (String poNumber)
Number blanketAmt;
CxBlanketAmtVOImpl blanketVO = (CxBlanketAmtVOImpl) getCxBlanketAmtVO1(); //VO to get total amount on the BlanketPO.
blanketVO.initQuery(poNumber);
Row row = blanketVO.getCurrentRow();
blanketAmt = (Number)row.getAttribute("Quantity"); //gets the blanket amt
if( blanketAmt != null ) {
return blanketAmt ; }
else { throw new OAException ("exception occurred", OAException.ERROR);   }
---------The code breaks at the line where I try to get "totalqty" or "blanketAmt" .. It throws a java nullpointer exception.
Thanks for helping me out.

The code breaks at the line 642: totalqty = (Number)row.getQuantityReleased();
I had already taken care of the null value in the VO sql query by using nvl(sum(release_amount), 0).. .so it should return atleast 0, if its null. But it returns "null" all the time.
I dont understand why its doing that. When I run the sql backend the query works fine and returns 0,even when there are no prior releases on the PO.
Thanks,

Null Pointer Exception Error's in WebDynpro Java

Hi All,
How Types are coming Null Pointer Exception Error's in WebDynpro Java, Please provide the types.of Errors.
Ex. Cardinality Type not correct etc...
Thanks,
Bye,
Vijay Hari.

HI
Null Pointer Exception can occur in may instances , for suppose
1) when you create a Value Node with some attribute which has cardinality , and you have not
initialized the Node , then it would through Null Pointer exception ,
2) when you integrate the RFC and parameters you pass as input to the RFC are not set correctly
then there could be null pointer when you execute the RFC
3>or may be when you doesnot bind the node when using webservice then there could be null pointer exception
and there could be many occurances for the exception

Java Null Pointer Exception - with arraycopy method.

Hi all,
I have been trying to fix this for a while now, but I think I've been staring at the screen for too long to fix it!
Basically I am trying to 'crossover' some arrays (evolutionary technique) but I keep getting a null pointer exception.
Here is my customised class: class ChromosomeDetails {
     double[] chromosomePrices;
     int[] chromosomePoints;
     int[] chromosomePlayerIDs;
     int chromosomeFitness;
     ChromosomeDetails(double[] chromosomePrices, int[] chromosomePoints, int[] chromosomePlayerIDs, int chromosomeFitness) {
          this.chromosomePrices = chromosomePrices;
          this.chromosomePoints = chromosomePoints;
          this.chromosomePlayerIDs = chromosomePlayerIDs;
          this.chromosomeFitness = chromosomeFitness;
     public ChromosomeDetails () {
          chromosomePrices = null;
          chromosomePoints = null;
          chromosomePlayerIDs = null;
          chromosomeFitness = 0;
     public double[] getPrices() {
          return chromosomePrices;
     public int[] getPoints() {
          return chromosomePoints;
     public int[] getPlayerIDs() {
          return chromosomePlayerIDs;
     public int getFitness() {
          return chromosomeFitness;
} In my main method I create 2 instances of this class like so:ChromosomeDetails parentChromosomeADetails = new ChromosomeDetails();
ChromosomeDetails parentChromosomeBDetails = new ChromosomeDetails();...and 2 other instances that are left empty:ChromosomeDetails childChromosomeCDetails = new ChromosomeDetails();
ChromosomeDetails childChromosomeDDetails = new ChromosomeDetails();     I then try to 'crossover' the values in the arrays like so: int randomCrossoverPoint = new Random().nextInt(parentChromosomeADetails.chromosomePoints.length-1);
System.arraycopy(parentChromosomeADetails.chromosomePrices, 0, childChromosomeCDetails.chromosomePrices, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePrices, randomCrossoverPoint, childChromosomeCDetails.chromosomePrices, randomCrossoverPoint, (childChromosomeCDetails.chromosomePrices.length-randomCrossoverPoint));
System.arraycopy(parentChromosomeADetails.chromosomePoints, 0, childChromosomeCDetails.chromosomePoints, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePoints, randomCrossoverPoint, childChromosomeCDetails.chromosomePoints, randomCrossoverPoint, (childChromosomeCDetails.chromosomePoints.length-randomCrossoverPoint));
System.arraycopy(parentChromosomeADetails.chromosomePlayerIDs, 0, childChromosomeCDetails.chromosomePlayerIDs, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePlayerIDs, randomCrossoverPoint, childChromosomeCDetails.chromosomePlayerIDs, randomCrossoverPoint, (childChromosomeCDetails.chromosomePlayerIDs.length-randomCrossoverPoint));
                    However it gives me this error, relating to the first arraycopy method: Exception in thread "main" java.lang.NullPointerException
     at java.lang.System.arraycopy(Native Method)Please note that in this program, parentChromosomeADetails and parentChromosomeBDetails already hold data when I try to use the arraycopy method, whereas the childChromosomeCDetails and childChromosomeDDetails objects are empty, waiting for the data from the arraycopy methods. Any help would be immensely appreciated.

it was learning very well yesterday, but that was before I introduced my customised class. I need my class as I need to be able to keep hold of all of the data, rather than just the chromosome points, so that I can see the exact strategy that the algorithm uses.
It is indeed the child chromosome that is null, and I suppose that it because I had to initialise the int[] chromosomePoints, double[] chromosomePrices and int[] chromosomePlayerIDs as null. What is the best solution to this? using loops to initialise all values in the arrays as 0 before the arraycopy?!

Java null pointer exception while getting a segment DFF handle

Hi,
my requirement is to make a field mandatory based upon a dff segment value (Y/N). i override PFR since segment is a poplist on the page (and poplists don't fire any event)
i searched in the "view source" of the page and found that segment id is ActFlexField0
when i click on save button i got "java null pointer exception"
here is code:
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean) throws OAException
+{+
+//get a handle to AM+
OAApplicationModule am;
am = oapagecontext.getRootApplicationModule();
oapagecontext.writeDiagnostics(this,"Root AM=>"oapagecontext.getApplicationModule(oawebbean).getName() ,1);+
if(oapagecontext.getParameter("applyCreActBut") != null || oapagecontext.getParameter("saveDtlBut") != null)
+{+
+/*Conditional mandatoryness of IdContribuente field*/+
+// first, find the flexfield's handle+
OADescriptiveFlexBean oaDFF;
oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");
+//oaDFF.processFlex(oapagecontext);+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
+//oapagecontext.writeDiagnostics(this, "Niccal: oamcb value is:"+oaDFF.getAttributeValue(), 1);+
+/*+
RenderingContext con = (RenderingContext) oapagecontext.getRenderingContext();
Enumeration x= null;
x= oaDFF.getChildNames(con);
oapagecontext.writeDiagnostics(this, "After getChild", 1);
while(x.hasMoreElements())
+{+
String aParamName = (String)x.nextElement();
oapagecontext.writeDiagnostics(this, "Niccal: DFF segment names are:"aParamName, 1);+
+//OAWebBean dffbeans=(OAWebBean)oaDFF.findChildRecursive(aParamName);+
+}+
+//oaDFF.mergeSegmentsWithParent(oapagecontext);+
OAMessageChoiceBean oamcb = (OAMessageChoiceBean)oaDFF.findChildRecursive("ActFlexField0");
+//String sIsForeign = (String)oaDFF.getAttributeValue("Attribute1");+
+//oapagecontext.writeDiagnostics(this, "Niccal: Attribute1 is:"+sIsForeign, 1);+
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);it's urgent
any help appreciated
thanx

hi Keerthi,
thank you.
i tried with below code but still unsuccesfully
+ oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
anyway i'm not able to reach your suggested if statement because execution stops before.
Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
page doesn't give error and saves data.
any suggestion appreciated,
thanx,
N

Java null pointer exception setting new preferences on a project

Using thw Warehouse Builder Client 9.0.3 with Oracle 9i 9.0.1, I tried to change the Naming option on the Naming Tab to the "logical name mode". Then i pressed the Ok button and this caused a crash with a Java Null Pointer Exception. At this time, All commands on project generated the same error responce. I shut down the machine, restarted the Oracle Instance and all related services, an as a result, I am not able to re-open no Warehouse Builder project. The system seems to be in an infinite loop while trying to open the currently selected project. Can anybody help me?
Thanks.

This seems to be a bug. Can you open a TAR on this?
