Hi
I want to check for duplicates in Supplier list when I am adding a new supplier.
I tried using this expresssion:
a!textField( label: "Supplier Name", value: fv!item.description, saveInto: fv!item.description, validations: { if( count(wherecontains(local!suppliers,index(fv!item,fv!index,{})))>1, "Supplier already exists",{} ) },
But I am getting the error -> Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!forEach [line 39]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function 'wherecontains' [line 52]: Invalid types, can only act on data of the same type (Any Type, Text)
I tried the methods mentioned in earlier posts but not able to fix it yet. Can someone help me?
Thanks
