a!recordFilterList in Order fulfillment app

...in direct response to your post: what specifically do you need help with understanding?

thanks for suggesting "Insert code" option.

items: append(cons!VOF_ALL_ANALYSTS, {"LoggedIn User", null}),
      expression: if(
        fv!isLast,
        a!recordFilterListOption(
          id: fv!index,
          name: "Unassigned",
          filter: a!queryFilter(
            field: 'recordType!{c5bfe4ef-1564-4630-a19f-cbdaa1880a48}HZN_JC_JobCosting_recordtype1.fields.{0293d097-e030-4431-9bcc-f5742790bb82}assignee',
            operator: "is null"
          )

I would like to know what is happening here in the above code. With respect to id, name. 

The overall purpose of the rule is to generate a list of values that will appear in a Record List 'User Filter' - that is, a filter that a User can select (in this case) one or more values to filter the list of Records by. 

Each item that will appear in the generated drop-down is of type 'a!recordFilterListOption', and the help for this type tells you what each attribute for that type is:

If you put your cursor inside the opening bracket for this function then you will see the above help appear in the bottom left of the expression editor:

Thank you for the reply Stewart Burchell

In my case, I have a form takes the user as a input and stores to the DB.

When I assign me as a user and check with defaultOption:"Me". 

I'm not able to see the records in the view.

Only when I enter loggedIn User in the DB then only that record is visible by default to me.

I suspect the issue is wiht this line:

items: append(cons!VOF_ALL_ANALYSTS, {"LoggedIn User", null}),

The intention appears to take the list of users in the cons!VOF_ALL_ANALYSTS and add to that list two additional items: the logged in user, and null. These are the values that are being used to apply a filter with, so the string "LoggedIn User" should actually be replaced with the function fn!loggedInUser() i.e.:

items: append(cons!VOF_ALL_ANALYSTS, {fn!loggedInUser(), null}),

how can we handle the condition when the loggedInUser is already present in the cons!VOF_ALL_ANALYSTS

what do you think needs to happen?

Thank you.

I was trying to encourage you to think through what you need to do in the situation where the looggedInUser value is already in the list contained in cons!VOF_ALL_ANALYSTS. Note: the what not the how. Half of delivering solutions is identifying what needs to be done and then the how then follows.
