"beforeUnSelect" javascript error

When I use the “beforeunselect” function,
If you do return false,
A javascript error will occur.


grid.events.on(“BeforeUnSelect”, function(row, col){
console.log(“beforeUnSelect”, row, col);
return false;

What’s the cause?
And can you solve it?

According to the Selection event docs, the beforeUnSelect is only available for:

The event can be applied to the DataView, List, Tree components.
