Not getting constant value?

[quote userid="2401" url="~/discussions/f/general/25080/not-getting-constant-value/97379#97379"]only displaying users read-only[/quote]

OP never said this (or really anything like it) beyond perhaps some incorrect assumptions in earlier replies.

Refer to this comment, where they [eventually] clarified a bit,

[quote userid="58556" url="~/discussions/f/general/25080/not-getting-constant-value/97288#97288"]I am using a!pickerFieldUsers() in interface, where I am trying to get values from two constant which contains groups. I want to display all the value present in two groups and from that only user can select only one user.[/quote]

My personal translation of this (going for what they mean, rather than their exact wording, that is) is something like the following:
"I am using a!pickerFieldUsers(), and want to allow it to select from among 2 distinct groups that I'm referencing using two constants, to allow the form user to make a single selection."

To which the answer is (as i posted before), OP needs to create a designated Parent Group to contain both target groups in question, and refer to that one in the picker field.

This thread is intriguing. My current questions are:

If you are only displaying users read-only, why do you need to do it in a picker field (vs a text field)?

Does this not work for you?

a!pickerFieldUsers(
  label: "Users",
  readOnly: true,
  value:getdistinctusers({
    cons!member1,
    cons!member2
  })
)

But then, this is what the value parameter of the field is used for.

yes you are right Mike Schmitt

To me this sounds like a great case for a!dropdownField() populated from 2 groups, with it's built-in search capability. Assuming the use case is #1, which is not yet clear here.

1) Select a single user from a list of users who are in one of 2 groups

2) Select a group (hence the pickerFieldGroups?), but have the members on display in a component nearby?

[quote userid="59361" url="~/discussions/f/general/25080/not-getting-constant-value/97292#97292"]why you try to use a user picker field to display users[/quote]

Consider that he might just be trying to ["see"] a certain set of users in the picker field, in the sense of the standard use case for the user picker field. That's my reading here.

I still do not understand why you try to use a user picker field to display users. While possible this does not make a great UI.

Have a look at the below pattern and replace the code in line 7 with the working code i posted.

as Stefan pointed out, the groupFilter parameter only accepts a single group input. If you want to allow your User Picker to access users from both groups, then you'll need to create a parent group with both of those groups as members, and point the picker field at that parent group instead. (You can wrap it in the same if() logic to check for the value of ri!pnrNo if you like).

I am using a!pickerFieldUsers() in interface, where I am trying to get values from two constant which contains groups. I want to display all the value present in two groups and from that only user can select only one user.

a!pickerFieldUsers(
maxSelections: 1,
groupFilter: if(
ri!pnrNo =2,
{cons!member1,cons!member2},{}
)
)

[assuming they're still trying to use a!pickerFieldGroups(), though i'm unclear on how or why.]

More details please! What do you try to do?

RE: Not getting constant value?

minhajk0001 — Tue, 05 Jul 2022 17:52:57 GMT

I have tried the above code in expression rule and I am able to get all the value. When I am using the above code in Interface that time it is throwing error i.e "Could not cast user to group"

RE: Not getting constant value?

Stefan Helzle — Tue, 05 Jul 2022 17:31:59 GMT

Does that code snippet work or not. It cannot work and also throw an error. More details please.

RE: Not getting constant value?

minhajk0001 — Tue, 05 Jul 2022 17:12:39 GMT

The above code is working and able to get the all the value from both the constant, but it is throwing Cast Invalid error "Could not cast user to group".

I already mentioned the getdistinctusers() function above. Try something like this:

a!forEach(
  items: getdistinctusers({cons!EOM_GROUP_ADMINS, cons!EOM_GROUP_GLOBAL_RISK}),
  expression: concat(
    user(fv!item, "firstName"),
    " ",
    user(fv!item, "lastName")
  )
)

I want to display the members of both groups. How to do it ?

RE: Not getting constant value?

Stefan Helzle — Mon, 04 Jul 2022 17:27:34 GMT

Do you want to display the members of both groups, or do you want to select users from both groups?

As I already wrote, this field only accepts a SINGLE group.

RE: Not getting constant value?

minhajk0001 — Mon, 04 Jul 2022 17:25:32 GMT

Here I want to display member from both the group, as of now it is showing only member belongs to member 1 only.

RE: Not getting constant value?

Stefan Helzle — Mon, 04 Jul 2022 17:08:39 GMT

You saw that this field only accepts a single group as filter?

RE: Not getting constant value?

minhajk0001 — Mon, 04 Jul 2022 16:59:36 GMT

a!pickerFieldGroups(
label: "TEST",
groupFilter: if(
ri!mod1 = 2,
{cons!member1, cons!member2},{}
)
)

this is the code, where I am getting only member1 value.

RE: Not getting constant value?

Stefan Helzle — Mon, 04 Jul 2022 16:25:17 GMT

OK, can you post a screenshot?

I assume that your constants are both of type Group. Now what do you expect as the output? The users being member of these groups? If this is the case, use the following function get them.

docs.appian.com/.../fnc_people_getdistinctusers.html

RE: Not getting constant value?

minhajk0001 — Mon, 04 Jul 2022 16:21:44 GMT

yes right empty list for other value, but I am able to get the value from cons!member1 .

Here I try to get get value from both cons!member1 & cons!member2 if ri!mod=2.

RE: Not getting constant value?

Stefan Helzle — Mon, 04 Jul 2022 16:17:13 GMT

Can you describe which outputs you get for your inputs?

I would expect that for ri!mod1 = 2 you get a list of groups. And empty list for any other value.
