[FNR] [Removing an Item of a Grouping Grid grouped by a nested property

[fullinet]

• Detailed description of the problem
  I have a grid grouped by for example store.groupBy("industry.name") where industry is a custom type (extending BaseModel or implementing BeanModelTag) and has a string property called name.
  If I remove an item from the store I get a JavaScriptException.
  
  Below is the stacktrace showed on the GWT Develoment Mode Console and a slightly modified version of the grouping grid example to support a graph of custom type objects.
  
  

  com.google.gwt.core.client.JavaScriptException: (TypeError): 'null' is null or not an object

I searched but I don't see that similar post, sorry...

There is any estimated time for the release 2.2? (The roadmap http://www.sencha.com/products/gwt/roadmap.php is not updated).

Thanks
