I'm working with a nintex form to implement changes at some process in the company.
I have a field in it form called Process. It is a choice field and is showed in the form as checkboxs.
The user can select the proccess that are present in the change that he would like to do.
I have another a list with two fields Process (text field type) and Approver (person or group field type)
When the user save the form a nintex workflow is started and I need to check in a list the process that the user selected and get the name of the approver for each process selected. Then I need to set the participants of the block called Start a Task Process with these approvers. I tried to do that with a foreach loop of the field process but i had not success.
Please, can someone help me to achieve this
Depending on how many lookup values you have, I would lean more towards building some validation rules into the form. Otherwise you will need to build a list lookup on the form, store the lookup data in a control (to be validated against) and then upon submit, run your validation rule. Keep in mind though, you will need to figure out a way to re-trigger your list lookup when the user goes back and makes their needed updates to submit. That is where you will run into the most pain
I would either build rules into the form specifically for it or, as suggested, add it to your workflow. Simply accept all forms, validate the data, and kick it back to the [Created By] if changes are needed.
Hope this helps!
You can achieve this requirement via out of the box validation on the column.
Go to List Settings --> Under Columns section --> click on your column name --> select "Enforce unique values" (this creates a indexed column).
Now, go to your Nintex form, and try entering a duplicate value to that column, and save, error message is shown, "The list item could not be added or updated because duplicate values were found in the following field in the list [Column Name].
Thank you Jesse, i thought to put all the items in the list in a control and then execute a rule that check if the all values Contains the number that the user input, but, how can i do to put in a control all values of a lookup list separated by ; or another character?
I can't do that in the workflow, i need it in the form.
Thanks a lot by your time
Thank you Krishna, but the destination of the form where i input the number is not the list where I have to check if this number exists. In my country, each person has a unique number that identify it as a worker. When a person was fired, i can't re hire to this person, then, i put it number in one list and check against this list if the person exists. This is the idea and is a specific solution for rural workers where is very common to re hire a workers.
Hi Hernan, thank you for the additional information on your requirement.
If you are maintaining a separate list with list of worker fired along with their numbers, you can follow below approach.
1. Handle "lost focus" event on the text box where entering the number
2. Write a function to handle this event --> in that function, query the other list (list of workers fired) and check that number exists in that list.
3. Show error message if that number exists, otherwise proceed.
Let me know if this approach is useful and need any additional help in implementation.
see similar question answered here - How to connect Forms with JS Function returning an argument
to adapt it to your case, you just need to check whether length(lookup(...)) returns a value greater then zero, which means the number appears in th elist.
note however a hint there why these kind of validations are not reliable.
