Hi All,
I have designed an interface which populates values in the fields based on dropdown value selected. The dropdown field is populated from a different table and rest other fields are from a different view.
But if the dropdown value is selected such that it does not exist in view then it given an error as shown below:
Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!multipleDropdownField [line 803]: Invalid index: Cannot index property 'cafNumber' of type String into type List of Variant

Hello Shubhamy,
It looks like that you have a cdt and you try to adress the parameter "cafNumber" ->"like " exampleCDT.cafNumber"That a typical message -> Is it possible that this exact moment examplcecdt is null? As consequence there would be no cafNumber to call available.-> try to use index() instead. https://docs.appian.com/suite/help/21.3/fnc_array_index.html "-> But if the dropdown value is selected such that it does not exist in view then it given an error as shown below:"
-> can you elaborate your steps more precisely?
