Hi,

I am trying to call the ConditionRefresh method wherein I am passing UInt32 value for SubscriptionId whereas expected datatype is IntegerId. Is this allowed – passing parent type where a child datatype is expected? 

I am getting Bad_SubscriptionIdInvalid error, so was wondering whether it was because of incorrect datatype being passed. 

Thanks,

Deepali

You can only pass values of built-in types in a method call.

If the information model datatype is not a built-in type then you need pass in a supertype.

In the case of IntegerId the basetype is UInt32 which means a UInt32 must be passed to the method call.

If the problem you are see was caused by a datatype mismatch you should get the BadTypeMismatch error code.
