dynamics crm 2011 - fetchXml: How to select accounts that *don't *have link entities of a specific type -

-

i want select accounts not n:n-related specific entity using fetchxml. tried following:

<fetch mapping="logical" count="50" version="1.0">     <entity name="account">         <attribute name="name" />         <order attribute="name" />         <link-entity name="xy_accounthierarchynode" from="xy_accountid"                             to="accountid" link-type="outer">             <filter>                 <condition attribute="xy_accounthierarchynodeid"                              operator="null" />             </filter>         </link-entity>     </entity> </fetch>

the expected result of query acounts don't have related xy_accounthierarchynode. receive accounts. filter conditions seems ignored...

what did wrong?

bad news not possible in crm 2011. getting accounts because using "outer" join.

there have been couple of creative ways of getting around this. example accounts or contacts without opportunities use marketing list approach described in this blog post.

good news crm 2013 released next month supports "left outer" joins give functionality looking for.

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
