ComboBox.select() when ContainerDatasource differs from PropertyDataSource

Hi all,

is there a possibility to preselect an item in a ComboBox, when the ContainerDatasource of the Box differs from the propertyDatasource?

Here is an example:


String[] list = {"1", "2", "3" };

ComboBox select = new ComboBox("", Arrays.asList(list));

box.setPropertyDataSource(SQLContainer().getItem(itemId).getItemProperty("number"));

box.select("2");

The box.select(“2”); command doesn’t work. If I do not use setPropertyDataSource(…); it works.
Has anybody a solution or workaround for this?

Thanks a lot!
Chris
