You mean , I should create two ElementLists , one for Thing.class and one for AnotherThing.class with the same name ?

Hi,
 
If the tags have the same name then you should not use @ElementListUnion, use @ElementList instead.

Hi,


 

I tried deseiarilizing a list object. Since I will know the type of the list only at run time , I declared it using ElementListUnion as :

 


Customer.java


 



           
@ElementListUnion({ @ElementList(inline = false, type = Thing.class),


                                   
@ElementList(inline = false, type = AnotherThing.class) })


          List<Object> things ;



 


My Response xml is :


 



<?xml version="1.0" encoding="UTF-8" standalone="yes"?>


<customer>


           
<address>


                       
<no>122</no>


                       
<street>chennai</street>


           
</address>


           
<id>122</id>


           
<name>James Bond</name>


           
<things>


                       
<thing>


                                   
<val>185</val>


                       
</thing>


                       
<thing>


                                   
<val>162</val>


                       
</thing>


           
</things>


</customer>



 


But Iam getting the following
exception. 


 



03-21 18:56:31.940: E/AndroidRuntime(2289): Caused by:


org.simpleframework.xml.core.PersistenceException: Duplicate annotation


of name 'things' on


@org.simpleframework.xml.ElementListUnion(value=[@org.simpleframework.xml.ElementList(data=false,


empty=true, entry=, inline=false, name=, required=true, type=class


com.data.Thing), @org.simpleframework.xml.ElementList(data=false,


empty=true, entry=, inline=false, name=, required=true, type=class


com.data.AnotherThing)]) on field 'things' java.util.List


com.data.Customer.things



 


When I remove one ElementList it works fine .


eg. : 


 




@ElementListUnion({ @ElementList(inline = false, type = Thing.class),


                                   
})


List<Object> things ;




 


is working fine.


 


Am I missing something here. Please Help. I have been on this for more than 3 days now.


 


Regards,


Shyam S
