Ext Designer throws an error when the tpl for a Date Column contains a formatted date. For example, if I have the following tpl for the Date Column.

HTML Code:
<span class="{[(new Date(values.TargetDate) < new Date() && values.StatusID == 1) ? "negative" : ""]}">{TargetDate:date(M d, Y)}</span>
I get this error:

The Designer version I'm using is - 1.2.3 Build 52.
