[jira] Updated: (TUSCANY-1226) Nulls go missing in CopyHelper

["Caroline Maynard (JIRA)" <tu...@ws.apache.org>]

     [ https://issues.apache.org/jira/browse/TUSCANY-1226?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Caroline Maynard updated TUSCANY-1226:
--------------------------------------

    Attachment: Tuscany-1226.patch

Got rid of the crash but didn't quite do it for me. Two reasons:
a) NULLs are not the same as empty strings. 
b) Still getting SDONullPointerExceptions out of resolveReferences()

The attached makes my tests run OK. How is it for you?

> This is perhaps a variation on Tuscany-1225. Problem is that when using CopyHelper to clone a DataObject, properties which are set to null remain unset in the destination DataObject.
> Example:
> SCHEMA:
> <?xml version="1.0" encoding="UTF-8"?>
> <schema xmlns="http://www.w3.org/2001/XMLSchema"
>         targetNamespace="PersonNamespace"
>         xmlns:AuthorNS="PersonNamespace">
>   <complexType name="personType">
>     <sequence>
>       <element name="name" type="string"/>
>       <element name="dob" type="string"/>
>       <element name="pob" type="string"/>
>     </sequence>
>   </complexType>
> </schema>
> logic:
> $xmldas = SDO_DAS_XML::create('person.xsd');
> $person = $xmldas->createDataObject('PersonNamespace','personType');
> $person->name = "William Shakespeare'";
> $person->dob = null;
> $person->pob = null;
> $person2 = clone($person);
> After the clone the php $person looks like: 
> object(SDO_DataObject)#3 (3) {name=>"William Shakespeare'"; dob=>NULL; pob=>NULL}
> but $person2 is:
> object(SDO_DataObject)#4 (3) {name=>"William Shakespeare'"; dob; pob}
> (I can't show you the Tuscany print of the DO, because it causes an AccessViolation :-) )
> Problem is perhaps that transferitem() doesn't consider nulls
