One idea I had was to do something like the following code:
This class would be added to the AutocompleteTextField (as below).
inputSoFar would be the input to the getChoices() method minus the string we
are looking for, so for example:
fred,jim,b
inputSoFar would be 'fred,jim'. input (to getChoices( String input )) would
be 'b' after chopping off "fred,jim," - once the user selects 'bob' from the
autocompleter, then input would be 'bob' also.
So finally in the ChangeBehavor class, inputSoFar + input would resolve to
"fred,jim,bob" and be populated in the text field.
Two problems with this:
a) It seems a bit hokey.
b) I have to store inputSoFar as a private member variable in the
AutocompleteTextField, which seems like an overhead to me.
Anyone got any thoughts?
Many thanks, Graeme.

@Override
protected void onUpdate( AjaxRequestTarget target )
{
String input = String.class.cast( getModelObject() );
setModel( new Model( inputSoFar + input ) );
target.addComponent( AutoCompleteContactTextField.this );
}
}
