I have created this rule to get the group names from my task report in a grid . but when there are multiple groups are present at assignee column, it gives error saying invalid group exception.

Here is the code:

 if(
  or(
    runtimetypeof(
      ri!groupOrUser
    ) = tointeger(
      'type!{http://www.appian.com/ae/types/2009}Group'
    ),
    like(
      ri!groupOrUser,
      "?Group:*"
    )
  ),
 touser(group(
    togroup(
      touniformstring(
        ri!groupOrUser
      )
    ),
    "groupName"
  )),
  rule!APN_displayUser(
    touser(
      ri!groupOrUser
    )
  )
)


Rule input-user or group

Any suggestions?

    This is hard to read.  Could you edit your post and throw all that code in a Code Box, with indentation restored, etc?

    (edited to add: thanks! much better now.)

    Also in case it helps, I have a similar task report which passes the value(s) in the "assignee" column into this rule, essentially "APN_displayGroupOrUser()", with a single rule input of type "user or group".

    if(
  runtimetypeof(ri!groupOrUser) = 'type!{http://www.appian.com/ae/types/2009}Group',
  if(
    isnull(ri!groupOrUser),
    null(),
    group(togroup(ri!groupOrUser), "groupName")
  ),
  rule!APN_displayUser(user: ri!groupOrUser)
)

    When there are list of groups like 2 groups  it doesn’t work . In expression rule it gives the group name for first group and at interface it through an error for invalid group exception

    Where and how are you trying to handle the assignee elements?  By default the report returns an array of assignment values (person or group), so in my interface I iterate over all such entries using a!forEach.
