How to remove an object

[Paul French]

This should be obvious but it isn't to me. I have generated classes from XML
schema with XMLBeans.

The names of the objects are irrevelant.

I do the following:

    businessDescription.addNewBS7666Coordinate().setX(12345);
    businessDescription.getBS7666Coordinate().setY(54321);

I want to remove the BS7666Coordinate object, how can I do this? I've tried:

    businessDescription.getBS7666Coordinate().setNil()

    businessDescription.setBS7666Coordinate(null)

Niether work? If I output the XML I get:

  <rol:BS7666Coordinate xsi:nil="true"/>


Since I cannot see how to remove it I want to modify the object that I have
added above and nullified by calling setNil:

    businessDescription.getBS7666Coordinate().setX(1111);
    businessDescription.getBS7666Coordinate().setY(2222);

This gives:

  <rol:BS7666Coordinate xsi:nil="true">
    <bs7:X>1111</bs7:X>
    <bs7:Y>2222</bs7:Y>
  </rol:BS7666Coordinate>

The nil attribute is still set?? Why? I can't see how to unset it.

If I try instead the following and attempt to replace the object with a new
one:

    businessDescription.addNewBS7666Coordinate().setX(1111);
    businessDescription.getBS7666Coordinate().setY(2222);

I get:

  <rol:BS7666Coordinate xsi:nil="true">
    <bs7:Y>6868</bs7:Y>
  </rol:BS7666Coordinate>

It appears the addNewBS7666Coordinate has failed yet passed back a valid
object since setX is called. Then getBS7666Coordinate is called which brings
back the orignal object and the Y value is set, hence the result. 

I must be miss understanding something fundamental about XMLBeans?

I suppose my question is how to add an object and then remove it and then
add another?

Any ideas?

Thanks
Paul
