  Fact: Interstage BPM Studio

   

  Fact: script action

   

  Symptom: String comparison performed in script action fails logically

   

  Fix:

  To specify two string comparison in script action, refer to BPM documentation ecma-262.pdf.

   

   

  See page 48 where it states: 

  String comparison can be forced by: "" + a == "" + b.

   

  See the below sample script code listing:

  // the highlight indicates that every string used for comparison contains prefex: "" +

  // the code listing below is used in script action in Init Action Set

  // it demonstrates how to check whether process initiator is admin user or not based on 

  // admin group specified in a UDA called AdminRole

   

  var initiator = sec.getProcessInitiator();
  Packages.java.lang.System.out.println("Process Initiator ====> " + initiator);
  var adminGroupName = uda.get("AdminRole");
  Packages.java.lang.System.out.println("Admin Group called ====> " + adminGroupName);

  var adminArray = sec.getGroupMembers(adminGroupName);
  var errMsg = null;
  var isAdmin = null;
  var bpmTrigger = "iflowtrigger"; // Process trigger in BPM is named as a fictitious user called "iflowtrigger"

  for (i=0; adminArray != null && i < adminArray.length; i++ ) {
  var adminUser = adminArray;
  Packages.java.lang.System.out.println("#" + (i+1) + ": admin retrieved: " + adminUser + ", while initiator is " + initiator);
  
  if ("" +initiator.toLowerCase() == "" +adminUser.toLowerCase() || "" +initiator.toLowerCase() == "" +bpmTrigger) {
  // initiator is BPM admin
  Packages.java.lang.System.out.println(initiator + " is admin user or iflowtrigger allowed to start the process.");
  isAdmin = "yes";
  uda.set("isAdmin","yes");
  break;
  }
  } // end of for loop

  
  if (isAdmin == null) {
  // not admin, print out the debug statement to command line console.
  Packages.java.lang.System.out.println(initiator + " is not allowed to start a process!");
  uda.set("isAdmin","no");
  //var errMsg = initiator + ", you are not a BPM admin and is not allowed to start a process!";
  //throw errMsg;
  }

  // end of sample script code listing
