Cannot reset border of subform?

[jnicholas330]

I am modifying the ColorFieldsValidation JavaScript to handle a situation where I want the entire subform containing any failed fields to be highlighted. The highlighting works well. However, even when the validation is successful, the highlighting persists. I believe I've narrowed it down to line 32, which seems to only remove the bottommost border. I realize this code was originally written to remove borders of fields, but why does it not also work for subforms?

function InitializeColorFields() {
    // Disable Acrobat's field highlighting. The Color
    // Failed Fields action takes care of highlighting fields.
    if (xfa.host.name == "Acrobat") {
        app.runtimeHighlight = false;
    }
}
function DoColorFields(oInvalidNode) {
    // If this form is running on a client other than Acrobat
    // (like on the server) then don't run this script
    if (xfa.host.name != "Acrobat") {
        return;
    }
    var sClassName = oInvalidNode.className;

    // Only contests, so nodes that are <field>s and
    // have name "Selected"
    // Ignore everything else
    if ((sClassName != "field") &&
        (oInvalidNode.name != "Selected")) {
        return;
    }

    //get closest Contest
    var nearestContest = oInvalidNode.resolveNode("Contest")
    if (oInvalidNode.errorText == "") {       
        // Validation Succeeded
        // Revert the appearance to its original state           
        console.println("we good for " + oInvalidNode.name);
        var oBorder = nearestContest.border;
        //does not work!       
        oBorder.parent.nodes.remove(oBorder);           

    }
    else {       
        // Validation Failed
        // Show the invalid appearance
        var oFailedBorder = nearestContest.border;
        // Border color
        // Show a solid border with square corners
        var sBorderColor;
            sBorderColor = "51, 102, 255";   
        if (sBorderColor != "none") {

            oFailedBorder.presence = "visible";

            for (var i = 0; i < 4; i++) {
                var oEdge = oFailedBorder.getElement("edge", i);

                oEdge.presence = "visible";
                oEdge.color.value = sBorderColor;
                oEdge.thickness = "2pt";
                oEdge.stroke = "solid";

                var oCorner = oFailedBorder.getElement("corner", i);

                oCorner.presence = "visible";
                oCorner.color.value = sBorderColor;
                oCorner.thickness = "2pt";
                oCorner.stroke = "solid";
                oCorner.join = "square";
                oCorner.inverted = "0";
                oCorner.radius = "0mm";
            }
        }

        // Background color
        // Show a solid fill color
        var sFillColor;       
        sFillColor = "153, 204, 255";

        if (sFillColor != "none") {
            // The presence of the border must be visible to show the fill.
            // Hide the edges when the invalid appearance doesn't include
            // changing the border color
            if (oFailedBorder.presence != "visible") {
                oFailedBorder.presence = "visible";
                oFailedBorder.edge.presence = "invisible";
            }

            // Replace the current fill type with a solid fill
            if (oFailedBorder.fill.oneOfChild.className != "solid") {
                var oFailedFillType = oFailedBorder.fill.oneOfChild;
                oFailedBorder.fill.nodes.remove(oFailedFillType);

                var oSolid = xfa.form.createNode("solid", "");           
                oFailedBorder.fill.nodes.append(oSolid);
            }
            oFailedBorder.fill.color.value = sFillColor;
        }       
    }
}

I "fixed" this issue by changing line 32 to this:

xfa.resolveNode(nearestContest.border.somExpression).presence = "invisible";

It seems that unlike a field's border, a subform's border cannot be removed.
