How to force validator method instead of data type validation in af:table

Question

This post will probably once again illustrate exactly how new I am to the Java/JDeveloper world so thanks in advance for any help! I have tried searching but couldn't find anything that seemed to mirror my problem.
I am using a modification of Frank's idea on how to individually color table cell backgrounds.
http://thepeninsulasedge.com/frank_nimphius/2008/04/10/adf-faces-conditionally-color-table-cell-background-2/
My intention was to use this along with custom validation to color cells with invalid values. It was a user request that it be done so as to quickly spot input errors (when updating records) if someone had missed the initial faces message and was no longer in the field that generated the error. It works fine for fields in my af:table based on VO attributes with varchar2 types but the 2 values with float and number types handle character input with a faces message "Not a number" and then do not seem to process the validator. The reason I (think I) need to use the validator in addition to Franks code is that in the validator code I use an addpartialtarget to the uicomponent that refreshes the background color if it changed in the backing bean.
FYI the project is based on ADF BC/JSF.
I tried gave the full use case as suggested so you understand what I am trying to accomplish and if you have a better way to accomplish this please let me know as well.
Thanks,
Rich
Managed-Bean
    public String getMODELColorString() {
        MODELColorString = "width:125px;";
        Object MODEL = getRowValue("#{row.ModelType}");
        if (MODEL != null) {
            if (!isValidMODEL(MODEL.toString())) {
                MODELColorString = "background-color:red;width:125px;";
        return MODELColorString;
    }Backing-Bean
        if (!myValidation.isValidMODEL(object.toString())) {
            System.out.println("InValid Data");
        AdfFacesContext.getCurrentInstance().addPartialTarget(uiComponent);P.S. If I made any newbie mistakes in my code please let me know, although this is obviously not production code yet by any means.

Frank (or anyone else who might offer some advice),
I thought that solved my issue as I could see the validator getting triggered, however something else is now happening. It seems to pass through the validator once for each of the values on my table with the invalid input I entered on one of the numbers, "a" in this case, and then once again through the color change backing bean but at that time the invalid input reverts to the original input and the change is rendered on the af:table as well. Any thoughts ? I put a print in the validator method, in the method that gets called from the validator (checks to see if value can be converted to float) , and then the color change bean (which also calls the float validation test) and pasted the output below.
