Hi, Just checked this has been fixed. I will make the final RC10 release now.

I get an error on starting up my application (which builds on uDig SDK rc9), here at the 'HACK' line: 

    if(selectedLayer != null && getSite()!=null &&
           getSite().getSelectionProvider()!=null ){
getSite().getSelectionProvider().setSelection(new StructuredSelection(selectedLayer)); 
    }else{
// HACK this makes the ContentModelItemProvider be added to the ContextModel getSite().getSelectionProvider().setSelection(new StructuredSelection()); 
    }
What's the purpose of this? Seems with the 'null' checks the failed line is going to always throw an error unless selectedLayer is the only null thing.
