    It could be that the line

    tointeger(index(fv!item, "id", null)) = tointeger(local!currentCRUDId),

    returns a list if one of the operands is a list. Then your foreach returns a list with some items be another list. Then reject() fails.

    A few hints:

    You can reference a type directly typing: 'type!{urn:com:appian:types:MECMS}MECMS_CRUDEntry'. You don't have to first create a data structure by calling the constructor, just to then extract the type from it.

    Then, the check for "local!currentCRUDId" does not depend on the items in the list and is either true or false for all items. Try to wrap the whole value expression into an if checking for "local!currentCRUDId".

  • Stefan Helzle  Thank you for the reply. I have fixed the issue by wrapping a!flatten function around for each function and it seems to be working
