Have a look at PDAcroForm.getFields(). You'll have to work with that, 
and if you don't find your field, call PDNonTerminalField.getChildren() 
on non terminal fields. When you find it, remove your field and reassign 
the list.

To find out whether you got your field, check the name or compare not 
the PDField object, but its getCOSObject() result.

Your solution in the recent mail might still work with a specific PDF, 
but I doubt it will work for all PDFs.
