Question

Hello, 
 I'm trying to implement a 'Check box' functionality, with only one choice label and one value, when I do that it throws me the following error 
 "Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!checkboxField [line 427]: A checkbox component [label=&ldquo;&rdquo;] has an invalid value for &ldquo;value&rdquo;. All selected values must be present in the choiceValues array, but value was 1 and choiceValues was 1." 
 Also please let me know what data type to assign for (1) Check box (2) Radio Buttons (3) Drop Down

Hello nellorea0001, 
 I replicated your issue, have a look it might be helpful for you. 
 here in the choice value, you are having an integer datatype, whereas in the rule input, there is a datatype mismatch. 
 use inverted commas and see if it works.

Best Regards, 
 Amit

Hi nellorea, 
 
Below code sample may help you which contains only one checkbox with one value to select. 
 
load( 
 local!checkbox1Input, 
 local!checkbox1Value: "Test", 
 with( 
 a!checkboxField( 
 label: "Check Box " & local!checkbox1Input, 
 choiceLabels: local!checkbox1Value, 
 choiceValues: local!checkbox1Value, 
 value: local!checkbox1Input, 
 saveInto: { 
 local!checkbox1Input 
 } 
 ) 
 ) 
) 
 
Thanks,

Hi nellorea0001, 
 
As per my understanding you need to check the data type of the rule input.This is also one of the reason for the issue occurred. 
 
please find the sample code and work around with your use case accordingly. 
 
a!checkboxField( 
 label: "Equipments", 
 labelPosition: "ABOVE", 
 choiceLabels: {"1262", "1264", "1266","1268","1270","1272"}, 
 choiceValues: {1, 2, 3, 4, 5, 6}, 
 value: ri!example, 
 saveinto: ri!example, 
 validations: {} 
) 
 
Thanks, 
ravalik

The value and choice value might have a datatype mismatch,you can solve the issue either by casting ( if you are using a localvariable in value,cast(1,local!value)or if you are using a rule input in the value change the data type to integer.

Hi, 
 
Seems like the choiceValues and Value are not same. Can you please check if you have double quotes in either the choiceValues or the Value, since that will make one value a integer and other a text, which will throw the error. 
 
The value for the checkbox should be within the list in the ChoiceValues list, if not it will throw an error. the below syntax will fail, because of the double quotes for value : "1", if you remove the quotes it should work. 
 
=a!checkboxField( 
 label: "Test", 
 instructions: "Test for Error", 
 choiceLabels: { 
 "Test" 
 }, 
 choiceValues: { 
 1 
 }, 
 value: {"1"} 
)

The datatype is based on what value you are saving, whether its a integer or text or boolean, based on that selection you can define the datatype. 
 
Thanks

Hi nellore, 
 
Below notes might be helpful for you 
->Choices display in the same order as defined in the Choice Labels parameter. The Choice Labels argument cannot be null. 
->Choice Labels and Choice Values must be the same length. 
->Choice Values cannot contain nulls or duplicate values. 
 
a!checkboxField( 
 label: "Label name", 
 instructions: "Instruction content", 
 choiceLabels: { 
 "Choice labelname" 
}, 
 choiceValues: { 
 "Choice labelvalue" 
 }, 
 value: ri!ruleInput, 
 saveInto: ri!ruleInput 
)

Could not display interface. Please check definition and inputs.
