I am trying to expect an array of strings in the webservice api. It says  
“Typed array input fields not supported yet”.  
Can anybody suggest me how I can expect an array in action\_webservices.

The code is as given below.

class SendInvitesApi \< ActionWebService::API::Base  
api\_method :send\_mails,  
:expects =\> [:invitation\_details =\>  
InvitationDetailsVO],  
:returns =\> [:string]  
end

class InvitationDetailsVO \< ActionWebService::Struct  
member :names, [:string] ##This is an array of strings.  
end

THNX in advance…

```
  :expects => [:invitation_details => InvitationDetailsVO],

```

I’m not sure that you’re allowed to tell the api to expect an object  
defined elswhere, I think it has to be one of the allowed xml types.  
Plus, what you’ve defined here is not an array because :expects needs an  
array anyway if you see what I mean. Try:

:expects =\> [[:invitation\_details =\> :string]]

Which will get your api to accept an array of strings. Your :returns  
method there returns a single string as it stands. If you want to return  
an array of strings use [[:string]].

PS. the AWS::Struct stuff is to allow to _return_ structures not defined  
as models. Not to accept them. Plus, in the case you have quoted about  
you don’t need to use a struct because you only have one member which is  
a normal type (array of string).
