Copy repeating section data to task form - but add one field for the task assignee

This has probably been asked and answered before, but is there not a way to bring repeating section data over from a start form into a task form, and then add a field for the task assignee to complete?

I’m developing an order form on which the initial user can use a repeating section to order items of equipment. After an approval process, the data is sent (via a task form) to the person who will fulfill the order. I don’t need this person to be able to edit any of the data from the start form’s repeating section; I just need a way for them to indicate the status of each item in the repeating section. For some items, they will be able to indicate that the item has been fulfilled because they have it in stock and can send it right away; other items will have to be ordered and then fulfilled later.

I can bring over the repeating section data to the task form, no problem. But what I’d like to do is have a field (Choice - Single) for each item in the repeating section where the task assignee can indicate if the item has been ordered or fulfilled. Of course you cannot add anything to a repeating section if it’s being brought over from the Start event variables.

I should add, in case this could be part of a potential solution, that the data from the start form is being written to a SharePoint list - each item in the repeating section being written as a separate item in the list - before the task is assigned to the order fulfiller.

Hi ​@DavidAD,

I think the easiest solution would be to make the fields in the task repeating section read-only and add a checkbox when the item is picked.

Start form:
 

 

Task Form:
 


I have attached the example workflow for your reference.

Crikey, ​@SimonMuntz, you’ve done it again! I knew about that relatively new default value field for repeating sections, but I guess I didn’t know how to use it. Thanks!

Hi, ​@Simon Muntz - I thought I had asked this question before, but I don’t see it anywhere now. 

I have a new use case in which I am using the same “trick” as noted above to populate the repeating section data in a task form while also adding new controls for the task assignee to complete. I have set that up successfully, but there is one hitch: one of the controls in the start form’s repeating section is a Choice - Multiple control. So basically it creates a collection (multiple-choice selections) within a collection (the repeating section data). And I don’t know how to pass those selections over to the task form’s repeating section.

In the Nintex help documentation for repeating sections, I found the following note. I believe it applies to my situation. But I guess I’m not understanding it, so I’ve added questions within the text.

  • For a Repeating section control that uses a collection variable, all control values in the data source must be at the root-level of the object, not nested. Only root-level values are used to map to form controls. Keep all mapped values at the root-level to simplify mapping and ensure the Repeating section displays correctly.

    If values from a nested object are required:

    1. Create a Text type form variable [where? in the start form or the task form?] that takes the nested object as input. [what exactly does this mean? I assume it means the set value is the collected values from the multiple-choice control - is it the overall collection of selections from each row in the repeating section, or is it the selections from the current row?]

    2. Convert the nested object to a string using the convertToString function. [Does this mean placing the function within the above variable and converting it to a string? Like convertToString(<<nested object value from step 1>>)?

    3. Use this variable in the Repeating section control by setting the Default value type to Text. [But I need the other controls in the task form’s repeating section to have the default value of Collection - don’t I?]

Thank you for any help you can provide.

Hi David,

I just tested this scenario, and I had no issues with a Choice multi-control.
I have a text short and a choice multi control.
It outputs:

["{\"se_choice_multiple_1_o0ynENZNFe\":[\"Option 1\",\"Option 3\"],\"se_text_short_1_5o58mnvgjb\":\"MyText\"}"]

I treated it the same as any other control, and it populated the repeating section in the task form as expected, even with multiple rows.
