change link color dynamically not working

I have a function that looks at cell values and if they are a negative number it changes their color property to red.
This is working fine except for cells that have a AW.Templates.Link template set.

Here is my function:
var addNegativeColor = function (obj,cells) {
obj.refresh();
obj.defineCellProperty("color", function(col, row){
if(cells.contains(col))
{
var val = this.getCellData(col, row);
return val < 0 ? "red" : "blue";
}
return "black";
});

obj.getCellTemplate().setStyle("color", function(){
return this.getControlProperty("color");
});
};

I am confused... If you are basing a cell color on it's value and checking to see if it is a negative number, how do you expect it to work on a link? By definition, a link is not a number so any function used on it as a number would fail. Do you have a column that has mixed information in it?

First to answer the above question, I'm using setCellData(myData) which contains unformatted numbers.
Then I'm applying the link with:
obj.setCellTemplate(new AW.Templates.Link, 16);
obj.setCellLink(function(c, r){return "ViewPaymentsMade.do?cycleID=" + myData[r][18];}, 16);

so in my color function, this.getCellData(col, row) actually returns the numeric value, not the link.

I've actually got it *mostly* working... just had to loop through the cells when getting the template:
var addNegativeColor = function (obj,cells) {
obj.defineCellProperty("color", function(col, row){
var val = this.getCellData(col, row);
return val < 0 ? "red" : "green";
});

for(var i = 0;i<cells.length;i++)
{
obj.getCellTemplate(cells[i]).setStyle("color", function(){
return this.getControlProperty("color");
});
}
};

This sets the color correctly, however, now when a row is highlighted the font remains the color set in my function, but it *should* turn to white like the default setting..... not sure how to accomplish this.
