Is there a way to prompt / accept a list of data from a user in a flow?



Been a few years since I've been working with flows and I'm sure it's changed a bit and forgotten a lot...


I am looking to do a flow where a flow will process a list.  


At first, I was looking to read that file in, but upon further info, this might be a problem (not all users would be able to put file where OO can read it).  


So, was wondering if there wasn't a way to prompt the user to enter in the list (list of IPs - could be as few as a couple or dozens).  


Iteration thru the list I don't think will be difficult, done this in the past and believe I can recall how to do that, but what I've not done and not sure if it's possible is to prompt for a list.  


Could I do it with Set Flow Variables?  My hope is that everything can be added in as one long list as below:



And then I could just use the List Iterator to mow thru that list.   Am I barking up the wrong tree?

Hello Chris,


It depends of the version of HP OO.


In version 10.x, you can create a list flow variable with a delimiter and then use operations to work on the list like: list iterator.


You can try this example out:

1. Assemble the Selection List flow as shown below.



  • Loop is in Library/Utility Operations/Looping in the Base cp.
  • List appender is in Utility  Operations/Flow Variable Manipulation in the Base cp.
  • The Selection List step is a renamed Do Nothing operation which you can locate in Library/Utility Operations/Flow Variable Manipulation in the Base cp.

2. Loop: Set the count input to a Constant Value of 5.


3. Modify List Appender inputs:

 - KeyName: Constant value of compiledList

 - resultText: Result of previous step

 - delimiter: , (comma)



4. Selection List step:

 - Remove all inputs except field1. Then modify the field1 input to present the selection list to the user


Parameters for field1 input:

 - Prompt For: Selection

- List Source: Flow Varible

- Named: compiledList

   You will have to type compiledList into the Named field as it is not available for selection in the drop-down list because of it only being generated at runtime at runtime trough the keyName input! (context key)

 - Source Delimiter: , (comma)

 - User message: Please make a selection:



 5. in the Display Message step, set the message input to a Constant alue of You selected: ${field1}.



 6. Save changes and run the flow in the Studio Debugger. When you run the flow, you will select a number from the pull down list.


 7. The number you selected is then displayed to you.


This is an example on how to work with a list on HP OO.
