how to sort AET attribute???????

Hi Friends,,

I am having one attribute EXT.ZFLD000008( AET attribute).. This attribute is available in the root context node BUILCONTACTPERSON... But it is not available in the BOL stucture ( in genil_model_editor if we check the attribute stucture means there we cannot able to find this attribute)

Get_xxx method of the attribute has some validation and  holds value each and every roundtrip...

Now my question is..

I have to sort the value of this attribute...Basically get_xxx method will trigger every round trip...

I need to collect all the values in to buffer to perform sorting

How can i store the value in buffer ??? Where I can write logic to perform the sorting...????

Thanks in Advance..
