Initializing a multivaluefield?

Hi
 
I am struggling to initialize the selected values for a 
multivaluefield.
 
In the flowscript I have the usual:
var model = myForm.getModel()
 
and for a simple text field I have something like:
model.myTextField = "foobar";
 
but when I try and set an array of values for the initial 
multivaluefield selection, I cannot seem to find the 
correct syntax e.g.
 
model.myMultivalueField[0] = "foo";
model.myMultivalueField[1] = "bar";
 
gives a null pointer error?
and 
 
model.myMultivalueField.push( "foo" );
 
gives a syntax error.
 
There is obviously a simple way to do this - please
help!
 
Thanks
Derek
 
P.S. I am not using Hibernate or any POJOs - just working
in POJ (Plain 'ol Javascript).

Sorry, that should have been   ... = new Array();    of course!

I confounded this with the widget.value

For what reason do you want to change the data model?
Before or after showing the page?

If after:
As far as I know the model is just a js-copy of the form-object's values.
So the member "myMultivalueField" is not initialized.

You could do it like:

model.myMultivalueField = new Object();
model.myMultivalueField[0] = "foo";
model.myMultivalueField[1] = "bar";

Or, if you want to change it before showing the page (eg. for setting the selection list on the widget), try:

values = new Array();
values[0] = 'foo';
values[0] = 'bar';
myForm.lookupWidget('myMultivalueField').setValue(values);

(set the data directly on the Form-Object!)
Actually I didn't test this variant yet- if it doesn't work, try the next one!

Or:

Values = new Array();
values[0] = {"value": "foo"};
values[1] = {"value": "bar"};
myForm.showForm("pipeName", {"myMultivalueField": values});
