RE: calling methods that take an array or list of interfaces

Maybe I am on the wrong track here, but in toArray() you need to pass in an
array. 

How can you create a new array of interfaces?  new WSite[...] creates the
real array (which implements IWSite, and has instanceof).

No, the prototype is "public void setSites(IWSite[] sites)."  It takes
IWSite[].  If you look in the error you will see that the values are
actually WSite.  Groovy just can't map them to IWSite[].  I am really
beginning to believe this is a bug and not just a syntax problem.  I just
find it hard to believe I am the first person to try this.

        Shouldn't it be:
        
        criteria.setSiteUuids( wsites.toArray(new WSite[wsites.size()]) );
        
        I.e. new Wsite not the interface.

        This is related to the email I sent a few days ago.  I can't figure
out how
        to pass arrays or list of interface pointers.
        
        Here is the method prototype:
        public void setSites(IWSite[] sites) {...}
        
        and the class declaration of WSite and IWSite:
        
        public class WSite implements IWSite {}
        
        This is the line from the script where wsites is an ArrayList of
IWSite
        objects.
        
        criteria.setSiteUuids( wsites.toArray(new IWSite[wsites.size()]) );
        
        And finally the error that I have become so frustrated with.
        No signature of method
        com.perfretail.k2v1.wake.reports.WReportsCriteria.setSiteUuids() is
        applicable for argument types:
([Lcom.perfretail.k2v1.wake.api.IWSite;)
        values: [[com.perfretail.k2v1.wake.core.WSite@8f83a9[name=Store
        100,uuid=afefe88416e94d9449186e9],
        com.perfretail.k2v1.wake.core.WSite@cf590[name=Store
        200,uuid=afefe88416e94fb44918796]]]
        As you can see it is an array of WSite, but it can't resolve it to
IWSite.
        The same behavior exists for methods that take in a List as an
argument as
        my previous email.
