Step by step guide how to show your workflow method log (using DfLogger) into Process Builder Console

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);
}
