Workflow Method Error: Invalid arguments passed while invoking method

Hi,

I have created a custom workflow method for one of my process requirement and it throws an error. Need help in resolving the issue or pointers on how to get into the root cause.

The method is created to achieve the following functionality.

1. Copy a package content to another package

2. Rename the content

3. Link the content of the package to a folder

The method takes 3 arguments of type string

1. r_object_id of src package

2. folder path where the package content to be linked

3. file name

The return type is string and represents r_object_id of the content copied.

The method throws following error while executing.

java.lang.RuntimeException: Invalid arguments passed while invoking method 'copyPDFTemplate from interface 'class com.****.yyy.workflow.bof.CopyPDFTemplateImpl' from BOF module 'com.****.yyy.workflow.bof.CopyPDFTemplate' in Process Template: 'outside_employment_wf' - Activity: 'Copy PDF Template'.

It would be helpful if you actually pasted your workflow method code. We cant read minds

Hi Johnny,

Thanks fore quick response. Following is the code for the method.

public class CopyPDFTemplateImpl extends DfSingleDocbaseModule implements CopyPDFTemplate {

@Override
public String copyPDFTemplate(String srcPackage, String folderLocation, String objectName) throws Exception {
// TODO Auto-generated method stub
IDfSession session = null;
IDfSysObject templateObject;
IDfCopyOperation copyOperation;
int i;
String targetFolder;
String copyPackage;
String newPackage;
String newObjectName = objectName;

IDfClientX clientx = new DfClientX();
try {
   session = getSession();
   targetFolder = folderLocation;
   copyPackage = srcPackage;
   if (targetFolder != null && targetFolder.length() > 0) {
    DfLogger.error(this, "targetFolder --> " + targetFolder, null, null);
    DfLogger.error(this, "srcPackage --> " + srcPackage, null, null);
    DfLogger.error(this, "objectName --> " + objectName, null, null);
    if (copyPackage != null && copyPackage.length() > 0) {
     templateObject = (IDfSysObject) session.getObject(new DfId(srcPackage));
     DfLogger.error(this, "templateObject --> " + templateObject.getObjectId(), null, null);
    } else {
     DfLogger.warn(this, "An object to copy is not specified in CopyObject.", null, null);
     return "Error";
    }
    if (!targetFolder.startsWith("/"))
     targetFolder = "/" + targetFolder;

    // Check if folder exists
    IDfFolder targetFolderObj = session.getFolderByPath(targetFolder);

     tempObject = (IDfSysObject) newSysObjects.get(i);
     if (tempObject.getObjectName().compareTo(templateObjName) == 0) {
      if (newObjectName == null || newObjectName.length() == 0) {
       newObjectName = tempObject.getObjectName();
      }
      theNewSysObject = tempObject;
     }
    }

    Calendar rightNow = Calendar.getInstance();
    int year = rightNow.get(Calendar.YEAR);
    int month = rightNow.get(Calendar.MONTH) + 1;
    int day = rightNow.get(Calendar.DAY_OF_MONTH);

   else {

    return "Error";
   }

            if (session != null) {
