Detelin Yordanov commented on AXIS2-3797:
-----------------------------------------

Hi Nandana,
  No I don't have a patch, but, I think that if I could bring Amila's attention 
to this, he could explain why this is not working and a provide
a possible workaround.
My understanding so far is that in Axis2 1.3 the anyType was serialized and 
deserialized as OMElement, but now in Axis2 1.4 that is not so.
I guess that decision was taken due to this jira: 
http://issues.apache.org/jira/browse/AXIS2-3331
And since the sample above was taken from one of the integration test clases, 
namely
org.apache.axis2.rpc.complex.ComplexDataTypesComplexDataTypesSOAP11Test#testretArrayAnyType1D(),
I checked that method again in Axis2 trunk and saw that it has been commented 
out by Amila, with the following comment:

"svn commit change the adb any type handling. currently it uses an om element 
to support
the anytype. but this is wrong. so I have change it to use the object to 
represent the anytype and the
serialize it accordingly. although this a current Axis2 1.3 bug, I put this 
commit only to trunk since
this is a bit large change."

So my question is whether there is a way to send OMElement in an Object array 
in the current version?
