Breakpoints is null

Hi!

I'm working on Vaadin-based project. Currently I'm trying to make RWD and have a problem. In browser console errors like this:

Where is the problems?

Hi, I think I have the same problem here.

Wed Nov 25 11:48:12 GMT+100 2015 com.vaadin.client.LayoutManager
SEVERE: Error in resize listenercom.google.gwt.core.client.JavaScriptException: (TypeError) : breakpoints is undefined
    at Unknown.$resolveBreakpoint(com.swisscreate.scbm.ui.widgetset.widgetset-0.js)

    at Unknown.$doLayout(com.swisscreate.scbm.ui.widgetset.widgetset-0.js)
...

This is the firebug output. I came across it when trying to create a responsive layout and it worked in IE and Chrome but not in FF. The width-range attribute was not added to the element. Then I removed the Responsive.makeResponsive(component) but I still got the mentioned error in Firefox.

Has anyone from the Vaadin team come accross this before?
 

Btw I am using Vaadin 7.4.6

Ok I upgraded to Vaadin 7.5.9 and the problem is gone!
