Problems with secondary methods in workflow

Hi experts.
I am starting my WF through the SAP_WAPI_START_WORKFLOW in SE37.
My WF consistst of a decision step with a secondary method, amodal method, which calls a custom method (call_url).
The method call_url has been tested in SE80 and in WF with synchronous dialog chain(BMWP) where it works fine.
Since UWL doesn`t support Synchronous dialog chain, I need to make a workaround.
Problem:
When I start the WF and enter MSS to open the workitem, I can see the attachment (call_url method). However, when I try to click on the link for the attachment (which is going to execute my custom method) I only get an errormessage.
The errormessage says:
"An error has occured during calling attachment. Try again and inform the system administrator about this problem".
I have been checkin SU53, it is not an authorization issue.
I have been reading Gatlings blog about secondary methods and searching the web about the issue with no luck.
Any ideas how to solve it?
<<text removed>>
Thanks in advance.
Best regards,
Tor

Ok, now i'm a little bit closer to the solution.
I've run thru the programm in debugging mode...
the reason is: function module SWO_INVOKE give me the return message OL850: You do not have authorization to execute method EDIT
But when the user calls the transaction ME52n everything is ok.
So what is the missing authorization object?
Thank you very much in advance

How to use secondary method in workflow?

Hi friends,
can anyone plz let me know how to use secondary methods in workflow? it would be helpful if u explain with an example..
thanks and regards,
Arun.S

Hi Arun Kumar,
The Sec Method can be used in the user decision step. The secondary methods are executed along with the user decision step. You have 3 options. Either execute a secondary method before executing the user decision step or after execution of user decision step or while executing the user decision.
For this define the methods either in Methods before execution of workitem execution to execute it before user decision step or Methods after execution of workitem so as to execute it after the execution of user decision.
In order to execute a method along with user decision step execution use secondary methods (amodal call.)
Let me know if you have any queries.
Regards,
Raj

Problem with traverse method

Hi, I am having this problem:
I made a CustomItem, a TextField, now I overloaded the traverse method, so if the keycode is Canvas.UP or Canvas.DOWN then return false else return true.
The problem is that when I press the left or rigth button it also returns false and not true.
and there is another problem with traverse, before returning false or true I set a boolean and call to repaint to draw it on some way if its selected or not, the paint method is being called but it just dont draw as desired.
protected void paint(Graphics g, int ancho, int alto) {
          System.out.println ("Dentro del paint, seleccionado="+seleccionado);
          try {
               g.drawString(label, 0, 0, Graphics.TOP|Graphics.LEFT);
               if (!seleccionado) {
                    g.setColor(120, 120, 120);
               g.drawRect(0, 4, tama�oTexto+8, 25);
               if (seleccionado) {
                    g.setColor(255, 255, 255);
                    g.fillRect(1, 5, (tama�oTexto+8-1), 23);
               g.setColor(0, 0, 0);
               if (!seleccionado) {
                    g.setColor(80, 80, 80);
               g.drawString(texto, 4, 7, Graphics.TOP|Graphics.LEFT);
               if (seleccionado) {
                    int cursorX=Font.getDefaultFont().charsWidth((texto.substring(0, idLetraActual)).toCharArray(), 0, texto.substring(0, idLetraActual).length())+4;
                    g.drawChar('|', cursorX, 7, Graphics.TOP|Graphics.LEFT);
          } catch (Exception E){
               E.printStackTrace();
     }the traverse method set the seleccionado variable and calls to repaint but instead of being false the paint method is drawing it as true (most of times).

I have a problem with findByxxx() method.. in
Container managed bean.
i have
Collection collection =
home.findByOwnerName("fieldValue");
specified in my Client Program, where ownerName is the
cmp fieldname..
and
public Collection findByOwnerName(String ownerName)
throws RemoteException, FinderException
defined in my home interface.
i have not mentioned the findBy() method anywhere else
(Bean class). You have to describe the query in the deployment descriptor.
>
Even if i have a same "fieldValue" in the database
(Oracle), which i specified in findBy() method, iam a
result of owner Not found, which is not the case as i
have that owner name.
for the same application if i use findByPrimaryKey(),
it is working..
Can any one please post me the solution.

Problem with prerender method

Hi,
I have a problem with the method prerender. A month ago, I started to develop a web project using Sun Studio Creator and a few page beans that i used extended the Abstract Page Bean, so I overrided the prerender and customized it.
The problem is that, now i'm using eclipse and the configuration files of the project has changed and the prerender method never execute.
I want to know why it is happening. Maybe the project is "bad-configurated"?
Thanks

The code of java bean doesn't change, the only thing that has changed is the configuration files (faces-config.xml, web.xml, etc).
I put a breakpoint in the prerender method but the lifecycle doesn�t execute this method.
After serveral changes, I wrote this code in the method prerender :
int i=0;
i = 1;
And the prerender method doesn't execute.
I'm a bit lost,
thanks

Problem with affinetransformOp method...

I have a serious problem with filter method
I Want to make a image flipping or some other filtering by using
AffineTransformOp
but it printouts an erro like this
cannot resolve symbol
op.filter (img, flipped)
(the error pointer shows ".after the op")
a code from my one of the filters
BufferedImage flipped = new BufferedImage(img.getHeight(), img.getWidth(),BufferedImage.TYPE_INT_RGB);
AffineTransform trans = new AffineTransform(0, 1, 1, 0, 0, 0);
AffineTransformOp op = new AffineTransformOp(trans, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
op.filter(img, flipped); //img is my buffered image source
I used some other ways like (img, null) but always give out error.
thanks..

Did you declare "img" as BufferedImage or something else?
What is the full error message?

Problem with WindowClosing() method

Hello everyone,
I have some problem with WindowClosing() method, in which I gave options
to quit or not. Quit is working fine but in case of Cancel, its not returning to
the frame. Can anyone help me ....Here is my code
import javax.swing.*;
import java.awt.*;
import javax.swing.event.*;
import java.awt.event.*;
public class TestFrame extends JPanel
     public static void main(String[] args)
          JFrame frame = new JFrame("Frame3");
          WindowListener l = new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
                    int button = JOptionPane.showConfirmDialog(null,"OK to Quit","",JOptionPane.YES_NO_OPTION, -1);
                    if(button == 0)     {
                         System.exit(0);
                               else
                                          return;
          frame.addWindowListener(l);
          frame.setSize(1200,950);
          frame.setLocationRelativeTo(null);
          frame.setVisible(true);
}

Maybe try
int button = JOptionPane.showConfirmDialog(yourframe,"OK to
Quit","",JOptionPane.YES_NO_OPTION, -1);

Issue with amodal secondary method in workflow

Java API, problem with secondary keys using multi key creator

Hi,
I'm developing an application that inserts a few 100k or so records into a Queue DB, then access them using one of four Hash SecondaryDatabases. Three of these secondary dbs use a SecondaryMultiKeyCreator to generate the keys, and one uses a SecondaryKeyCreator. As a test, I'm trying to iterate through each secondary key. When trying to iterate through the keys of any of the secondary databases that use a SecondaryMultiKeyCreator, I have problems. I'm attempting to iterate through the keys by:
1: creating a StoredMap of the SecondaryDatabase
2: getting a StoredKeySet from said map
3: getting a StoredIterator on said StoredKeySet
4: iterate
The first call to StoredIterator.next() fails at my key binding (TupleBinding) because it is only receiving 2 bytes of data for the key, when it should be getting more, so an Exception is thrown. I suspected a problem with my SecondaryMultiKeyCreator, so I added some debug code to check the size of the DatabaseEntries it creates immediately before adding them to the results key Set. It checks out right. I also checked my key binding like so:
1: use binding to convert the key object to a DatabaseEntry
2: use binding to convert the created DatabaseEntry back to a key object
3: check to see if the old object contains the same data as the new one
Everything checked out ok.
What it boils down to is this: my key creator is adding DatabaseEntries of the correct size to the results set, but when the keys are being read back later on, my key binding is only receiving 2 bytes of data. For the one SecondaryDatabase that doesn't use a SecondaryMultiKeyCreator, but just a SecondaryKeyCreator, there are no issues and I am able to iterate through its secondary keys as expected.
EDIT: New discovery: if I only add ONE DatabaseEntry to the results set in my SecondaryMultiKeyCreator, I am able to iterate through the keys as I would like to.
Any ideas or suggestions?
Thank you for your attention,
-Justin

Hi Justin,
Sorry about the delayed response here. I have created a patch that resolves the problem.
If you apply the patch to your 4.6.21 source tree, and then rebuild Berkeley DB, the improper behavior should be resolved.

User Decision with Secondary Method

Dear All,
I have created a user decision step for Leave Request workflow (ie. to approve or reject ).
This is done for multiple approvals of leave request through UWL i.e. user can select multiple requests & take decisions(approve/reject).
In the user decision step, i want to use a method other than standard task TS00008267.
In the methods tab i have used Secondary Method,
Object Category as Class
Obj.Type as CL_PT_REQ_WF_ATTRIBS
Method DUMMY.( as per the standard workflow - WS12300111).
But no value is returned by this method. How can binding be done here so as to use the values in further steps??
Please help.
Regards,
Vidya

Hey it is very easy to know whetehr the leave is approved or not. and even you can get this decision into the workflow container
No need of using any secondary methods SURE
See the step Approval in the Leave workflow will use Dummy method of that class that you have mentioned.
Your staus is updated in the REQ container element of the workflow , it is the that you mentioned, in that class you have a attribute with name Status whe you approve it will be changed to Approved when the leave is created it will be Sent , so by using a Condition step check this attribute value if it is approved then in update one conatiner element by using Container operation step.

Problem with getPrimaryKeys method in DatabaseMetaData

I'm using the above mentioned method to get primary keys from a DB2 database. I estimate that 95% of the time it performs as expected, but there are 7 tables in my database, that as far as I can see, are no different to any others and it fails to work with these. Looking at the tables in the DB2 control centre shows them all having keys, no different to any of the other tables. Also of note is that the tables it fails on are next to each other, it fails on tables 68 and 69, 135 and 136 and 200,201 and 202. Just wondering if anyone else has seen this problem before and if they found any solutions for it?
Just ran through the program again and it's failed on a completely different set of tables, they're all sequential as well, could this be a problem with my connection to the db?
Edited by: jnaish on Aug 14, 2008 7:38 AM

post the ddl and code i guess
i doubt this is related to your connection
Also of note is that the tables it fails on are next to each other, i can't imagine that would be a problem, but sounds like it'd be easy for you to prove your theory with a simple test

Problem with Vector method addElement

I am new to Java. I am using JDK 1.3. I am writing a program that will convert a text file to a binary file that stores a Vector object. I have narrowed my problem to the method that reads the text file and creates my vector. Each element in my vector stores an integer and a string variable. The reading of the text file works find and the creation of my record works find. It seems that the storing of the record in the vector is not working. When I print the first 10 elements of the vector, it have the same record(the last record of my text file). What is wrong with the method below? I am also appending the result of running my program.
private static void readTextFile(File f) {
try {
FileReader fileIn = new FileReader(f);
BufferedReader in = new BufferedReader(fileIn);
String line;
int i;
SsnLocationRecord recordIn = new SsnLocationRecord();
int ctr = 0;
while (true) {
line = in.readLine();
if (line == null)
break;
ctr += 1;
i = line.indexOf(" ");
recordIn.putAreaNumber(Integer.parseInt(line.substring(0,i).trim()));
recordIn.putLocation(line.substring(i+1).trim());
records.addElement(recordIn);
if (ctr < 11)
System.out.println(recordIn);
in.close();
} catch (IOException e) {
System.out.println ("Error reading file");
System.exit(0);
for (int i = 0; i < 11; i++)
System.out.println((SsnLocationRecord) records.elementAt(i));
RESULTS:

First of all it would be better if you did a priming read and then checked line == null in the while statement instead of the way you have it.
ctr++ will also accomplish what ctr +=1 is doing.
you need to create a new instance of SsnLocationRecord for each line read. What you are doing is overlaying the objects data each time you execute the .putxxxx methods. The reference to the object is placed in the vector. The actual object is still being updated by the .putxxx methods (NOTE : THIS IS THE ANSWER TO YOUR MAIN QUESTION).
you close should be in a finally statement.
To process through all the elements of a Vector create an Enumeration and then use the nextElement() method instead of the elementAt is probably better. (Some will argue with me on this I am sure).
Also, on a catch do not call System.exit(0). This will end your JVM normally. Instead throw an Exception (Runtime or Error level if you want an abnormal end).

Problem with GetLineData Method

Hi
I have a program to save each row of a A/R Invoice as one A/R Invoice document.
In the program, I read each line of data from matrix with GetLineData Method, and set the data to business object, and add the document at a global transaction.
Adding the first line of document works fine, but the second line has a problem. There is no response in the the GetLineData Method.
Does anybody have any idea?
The code looks like the following:
Private Sub MakeSalesInvoice(ByRef BubbleEvent As Boolean)
     Dim i As Integer
       Try
            If Not (SBO_COMPANY.InTransaction) Then
                Call SBO_COMPANY.StartTransaction()
            End If

Can someone help me?
Thanks in advance.

Thanks for the response.
I tried GetLineData(i-1), but got error "Row - Invalid index" message.
I think the index of the datasource has no problem in my program since i set -1 when i get the data from datasource.
The following is the code when setting data to the business objects.
Private Sub subSetInvoiceH()
        Dim nCount As Integer
        Dim oDBDataSource As SAPbouiCOM.DBDataSource
        oDBDataSource = oDBDataSources.Item("OINV")
        nCount = oDBDataSource.Size - 1
        InvoiceH = SBO_COMPANY.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oInvoices)
        With InvoiceH
            If oDBDataSource.GetValue("CardCode", nCount) <> "" Then
                .CardCode = oDBDataSource.GetValue("CardCode", nCount)
            Else
                .CardCode = ""
            End If
            If oDBDataSource.GetValue("DocDate", nCount) <> "" Then
                .DocDate = oDBDataSource.GetValue("DocDate", nCount).Insert(4, "/").Insert(7, "/")
            Else
                .DocDate = "0"
            End If
        End With

Problem with binarySearch method

In the code below I've got a problem with my binarySearach method in the IntegerList.java file. When I look at my IntegerTest file, Eclipse give me this message next to my method call for the binarySerch (case 6): (the method binarySearch int[] , int) in the type integerList is not applicable for the arguments (int). So what the heck have I done wrong? I know it's a lot of code to look at but felt you'll need to see both classes to make heads or tales out of this.
Thanks in advance.

Ah... But now that I have looked at it some more, I have noticed that the array of int is created in your IntegerList class...
so you want to change your binarySearch() method...
from...
public static int binarySearch (int[] list,int val)to
public int binarySearch (int val)now it will search the list declared in your constructor...
and also note that static is remove to eliminate the non-static reference from static context error...
so in IntegerList.java, that method signature should look like this...
public int binarySearch (int val)// take only one arguement and...
// check against internal int [] listand you call it like this...
loc = list.binarySearch(val);// not changednow all you have to do it get your list populated with random integers for the rest to work... I leave that to you...
