Dear list,

I am trying to return a distinct list of objects via the
EOFetchSpecification. I¹ve always had good luck with the simple
³EOFetchSpecification spec = new EOFetchSpecification("myentity", qualifier,
null);² statement. But when I try adding a boolean to the ŒusesDistinct¹
parameter of the constructor I get an error. ie. neither of these work:


EOFetchSpecification spec = new EOFetchSpecification("SyncShared",
qualifier, myOrderings, boolTrue);
-or-   EOFetchSpecification spec = new EOFetchSpecification("SyncShared",
qualifier, null, boolTrue);

The API does list this forth parameter as a boolean (true means distinct,
false otherwise). public EOFetchSpecification(String entityName,
EOQualifier qualifier,
NSArray sortOrderings,
boolean usesDistinct,
boolean isDeep,
NSDictionary hints)


Here is the error I get when I try to build:

syncaccountcreate.java:42: cannot resolve symbol
symbol : constructor EOFetchSpecification
(java.lang.String,com.webobjects.eocontrol.EOQualifier,com.webobjects.founda


tion.NSArray,boolean)

Thanks for any guidance, and for pointing out what my be painfully simple.
:)

Your trying to call a method that does not exist. The error above is telling you that you have the wrong arguments in your method call. Your method call arguments are:

String,
EOQualifier,
NSArray,
boolean

But the signature you have listed from the api has five arguments.

Ooopps!, six arguments. :P


String, EOQualifier, NSArray, boolean,
boolean, <-----
NSDictionary
