<div><br></div><div>Here is the scenario: I have a domain object with an attribute displayed in a drop-down list. Some other session updates the attribute. I refresh my display, but the rendered selection does not change. Using Firebug, the generated html shows the updated selection. This may be basic HTML knowledge, but should the displayed value not update to show the changed 'selected' option? Or is the value intended to be set only on the initial page display and then only by a user action?</div>
<div><br></div><div>Here is an example. I have a demo Seaside component with a class variable #testStateListSelection which is selected to 'one' in a Seaside session. If I change the value to 'three' in another Seaside session, the displayed value stays as 'one' in the original session after rendering again, even though the "selected" in the generated HTML shows "three".</div>
