Hello,

Sorry if it was already considered here.

GridPanel.js in v.3.1.1 contains the following fragment:

Code:
    
    processEvent : function(name, e){

    //....
        this.view.processEvent(name, e);
    },
I've changed it to

Code:
    
    processEvent : function(name, e){

    //....
        if (this.view) this.view.processEvent(name, e);
    },
and some js errors are gone (IE8, strict mode).

It seems that processEvent can be called when the grid is already destroyed (in my case, a js code erasing the top panel was loaded on cell click).
