LUIS ActionBinding Param Library doesnt display if enum - botframework

Question

If I specify as enum then it doesn't get displayed in the dialog. Can anyone help to point out if am missing some thing?
[LuisActionBinding("CollPay", FriendlyName = "Reminder")]
public class CollPayAction : BaseLuisAction
{
public enum PaymentAmtOptions
{
[Terms(new string[] { "Full Payment", "Entire Amount", "Full Due Amount" })]
FullPayment = 1,
[Terms(new string[] { "Clubbed Payment", "Combined Payment" })]
CombinedPayment
};
[Required(ErrorMessage = "Are you planning to make a separate payment or combined one?")]
[LuisActionBindingParam(CustomType = "BOPYMTOPTION", Order = 2)]
[Template(TemplateUsage.EnumSelectOne, "Are you planning to make a separate payment or combined one? {||}",
"How would you like to make the payment - separate for each Invoice(or) clubbed with other pending dues? {||}")]
public PaymentAmtOptions PaymentAmount { get; set; }
public override Task<object> FulfillAsync()
{
var result = string.Format("Hello! You have reached the CollPay intent");
return Task.FromResult((object)result);
}
}

Thanks for reporting this, it was certainly an issue. The good news is that a PR with a patch was already created.
Once the PR is approved, you will have to update your code:
-To use the updated library
-To validate the enum value. Below you will find how the code could look like:
[LuisActionBinding("CollPay", FriendlyName = "Reminder")]
public class CollPayAction : BaseLuisAction
{
public enum PaymentAmtOptions
{
None = 0, // default - no option selected
FullPayment = 1,
CombinedPayment = 2
};
// custom validator for my enum value
public class ValidPaymentAttribute : ValidationAttribute
{
public override bool IsValid(object value)
{
return value is PaymentAmtOptions && ((PaymentAmtOptions)value) != PaymentAmtOptions.None;
}
}
[ValidPayment(ErrorMessage = "Are you planning to make a separate payment [FullPayment] or combined one [CombinedPayment]?")]
[LuisActionBindingParam(CustomType = "BOPYMTOPTION", Order = 2)]
public PaymentAmtOptions PaymentAmount { get; set; }
public override Task<object> FulfillAsync()
{
var result = string.Format("Hello! You have reached the CollPay intent");
return Task.FromResult((object)result);
}
}
