ForEach Expression Rule not returning list as desired. Please advise.

Question

Below is the expression rule. 
 a!forEach( items: ri!NSARequest.SelectedApprovalTeams, expression: { if(rule!NSA_GetStatusOfApprovalTeam_ExprRule(ri!NSARequest, fv!item) = "Pending", fv!item, null) } ) 
 
 Rule Input Value being passed in Test Case: 
 { AAGRequest: {Status: "Pending"}, OGCRequest: {Status: "Completed"}, SelectedApprovalTeams: { cons!NSA_AAG_Name_Cons, cons!NSA_OGC_Name_Cons } } 
 It is returning null and count 2 even if the input list passed has only one "Pending" status request. 
 List of Variant: 2 items List of Text String: 1 item "Architecture Assurance Group" List of Text String: 1 item null (Text)

It's not clear what you're asking. 
 If you want to return the following, just get rid of the curly braces following expression in the a!foreach loop. 
 List of Text String: 2 items
 "AAGRequest"
 null (Text) 
 
 If you want to get rid of the null entry, clean up the resulting list using something like reject(fn!isnull, local!list) .

Hello, 
 
The reason why you are getting 2 values. Is because you are looping SelectedApprovalTeams, which actually has 2 values. 
 
The reason to get null values is that the rule NSA_GetStatusOfApprovalTeam_ExprRule each time is not returning pending, consequently it goes to the falseValue of the “ir function” which has null value. 
 
That is definitely a normal behavior. You can use Carlos suggestion on the reject or filter, or pass {} instead of null and use flatten.
