BUG: Inconsistent behavior of getCurrentColumn

It took me a while to find a way around this bug in the Grid in version 2.0.1:

I need different behavior when the enter key is clicked, depending on the column. I decided to put the options in a switch/case structure. It turned out that getCurrentColumn was returning a digit if I had navigated to the cell using the arrow keys, but returning a string if I had selected the cell with the mouse!

My solution (which is obviously a work-around) was to cast the returned value to an integer in order to have consistent values to test in the switch cases.

Here's the code:

grid6.onKeyEnter = function(event){
gc = parseInt(grid6.getCurrentColumn());
gr = parseInt(grid6.getCurrentRow());
//alert("current cell: " + gc + "," + gr);
switch(gc){
case 0:
//alert("Setting default to row " + gr);
setDefaultRow(gr);
break;
case 1:
break;
case 2:
break;
case 3:
removeRow(gr);
break;
case 4:
//moveRowDown(gr);
break;
case 5:
//moveRowUp(gr);
break;
default:
//do nothing
break;
}
};

Yes, the original idea was to support any string in template indices, not just numbers, so you have to convert them to numbers for doing any arithmetics or numeric comparison. However I agree that the behavior should be at least consistent.
