Migrating from Vaadin 7.0 to Vaadin 7.1 - progress bar problem

Hello, we recently migrated to Vaadin 7.1 everything works fine except progress bar.
I have changed ProgressIndicator class to ProgressBar and also call setPollInterval method but my progress bar
looks like picture in attachment and it’s independent of indeterminate mode.
Please help.


Update: I have faced this problem, it was just necessary to set height to my progress box which contains progress bar.
