Accordion and ViewStack use deferred instantiation by default. This means that until a user navigates to that view, the contents are not available for reading or setting.
The quick fix is to set creationPolicy="all" on the container. However, this will remove the benefit to perceived performance that deferred instantiation provides. See the docs for more info on controlling instatiation.

If the results change when the datagrid is visible, it works. Any clue?
