Changing locales in the samples_easy_localization project does not update preview

[fertrig]

In the samples_easy_localization project, when you select a story and then select a different locale, the story in the preview does not update with the new locale.

The workaround is to select something else on the controller, then the preview will update with the new locale.

The samples_intl_tools project works as expected though. There is something about the samples_easy_localization implementation that is causing this issue.
