Answer:

From the stack trace, an error was occured on at com.documentum.bps.functions.DateToStringFunction.execute(DateToStringFunction.java:33).

The source of that method

1
2
3
4

    if ((paramArrayOfObject == null) || (paramArrayOfObject.length <= 1) || 
(paramArrayOfObject.length > 2) || (!(paramArrayOfObject[0] instanceof Date)) || 
(!(paramArrayOfObject[1] instanceof String)))
    {
      throw new IllegalArgumentException();
    }

To summary possible condition that can raise this error are:

• If parameter of DateToString function is not exactly 2 parameter
• If the first parameter is not date
• If the second parameter is not string (date format)
• If the first parameter date is equal to "nulldate"

Question: I cannot compile a workflow method that using IDfWorkitemEx interface.

Answer: IDfWorkitemEx interface is enhanced version of IDfWorkitem. In case you want to use (import) this interface in your workflow method, simply add bpm_infra.jar to your classpath (eclipse project classpath). bpm_infra.jar is usually located at C:\Program Files\Documentum\Shared.

IDfWorkitemEx can be used to retrieve workflow's process variables, example:

1
2
3
4
5
6
7

/* Updating process variables, i.e sdt. For more info on IDfWorkitemEx, 
refer to java doc corresponding to com.documentum. BPM.IDfWorkitemEx*/
if (workitem instanceof IDfWorkitemEx) {
	IDfWorkitemEx workitemEx = (IDfWorkitemEx) workitem;
	Object var0 = workitemEx.getPrimitiveVariableValue("Var0");
	//Some useful operation with var0
	workitemEx.setPrimitiveObjectValue("Var0", var0);
}
