getFormulaFunction patch

[senordhuff]

Hello,

Because we dynamically add and remove fields to our grids, we ran into a problem with getFormulaFunction. Here is the patch. Simple null check needed on _1 that is passed in...

if (window.isc && (isc.version.indexOf("v8.3")>-1)) {
	
	isc.Canvas.getPrototype().addProperties({
		
		getFormulaFunction:function(_1){
			//5/9/13
			//null check on field
			if(_1==null || !_1.userFormula)return null;
			var _2=_1.$65w;
			if(_2!=null&&_2.$111j==_1.userFormula)return _2;
			_2=_1.$65w=isc.FormulaBuilder.generateFunction(_1.userFormula,this.getAllFields(),this);
			_2.$111j=_1.userFormula;
			var _3=function(_4,_1,_5){return _2(_4,_5)};
			_1.sortNormalizer=_3;
			return _2
		}
				

	})
}

That looks like a safe change at first glance.
We'll do a little checking and roll it into the product.

Thanks for pinning it down
