Lcds 3.1 hibernateannotations problem

Question

I'm trying to use hibernateannotations with lcds 3.1 and flexbuilder 4.5.1 and I'm having problem getting the fill operation to work, I'm not sure what I'm doing wrong
I'm getting this error back from lcds:
[LCDS]Exception executing assembler operation.  incomingMessage: Flex Message (flex.data.messages.DataMessageExt)
    operation = fill
    id = null
    clientId = C1DFF41D-2A96-1A63-E293-F4CB0FEEE405
    correlationId =
    destination = WrUesdDataManagerService
    messageId = 9861843C-94CA-9656-D044-F4CB1029A6AC
    timestamp = 1322661908887
    timeToLive = 0
    body =
      [[], getAllSorted, [Ljava.lang.Object;@7d6b4be5]
    hdr(DSId) = D8A3C599-C32F-EA78-D64B-978BE213BFC3
    hdr(DSEndpoint) = my-rtmp
    exception: java.lang.ClassCastException: flex.messaging.io.ArrayCollection cannot be cast to java.lang.String
    at flex.data.assemblers.HibernateAssembler.fill(HibernateAssembler.java:1034)

    at flex.data.adapters.JavaAdapter.invokeFillOperation(JavaAdapter.java:996)
    at flex.data.adapters.JavaAdapter.invoke(JavaAdapter.java:622)
my actionscript looks like this:
var param:ArrayCollection = new ArrayCollection();
                param.addItem(jobs);
                param.addItem("getAllSorted");
                param.addItem([]);
                getAllResult.token = WrUesdDataService.fill(param);
and I've went through commenting out the various params like jobs and [] but I still get the same error
the using lcds 3.1 doc says fills should like this
myService.fill(myCollection, "flex:hql", "from Person p where p.firstName = ? ", ["Paul"]);
but the compiler doesn't that syntax.
I created the service by importing it into the data model and generating the code.
here is my data-managementconfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<service id="data-service"
    class="flex.data.DataService">
    <adapters>
        <adapter-definition id="actionscript" class="flex.data.adapters.ASObjectAdapter" default="true"/>
        <adapter-definition id="java-dao" class="flex.data.adapters.JavaAdapter"/>
    </adapters>
        <default-channels>
        <channel ref="my-rtmp"/>
    </default-channels>
<destination id="WrUesdDataManagerService">
       <adapter ref="java-dao" />
       <properties>
<source>flex.data.assemblers.HibernateAnnotationsAssembler</source>
       <item-class>gov.llnl.castlewr.model.WrUesdData</item-class>
       <scope>application</scope>
       <metadata>
      <identity property="uesdId"/>
      </metadata>
      <server>
        <fill-configuration>
                <use-query-cache>false</use-query-cache>
                <allow-hql-queries>true</allow-hql-queries>
            </fill-configuration>
      </server>
      </properties>
      </destination>
</service>
any suggestions?

The compiler wants  WrDataService.fill(arg0:ArrayCollection) which I assumed are the 3 args listed for the fill, (collection, query, queryparams)
