We are in the process of converting all Designer forms into XDP files then uploading to AEM. In this process, I have discovered that the time object validations are not working in HTML. When the user types the value into these objects (we have a 12 hour and 24 hour object created), it simply disappears upon exit. I've tried to use multiple validation formats and get nothing but a Validation error, even when I type it exactly what the validation calls for. This field works perfectly in the "Preview PDF" tab but not the "Preview HTML" tab. Does anyone know if this is a common issue and what is the work around for this?
Here are some links for the comparison of PDF and HTML5 renditions:
Also check if your locale settings match the expected locale in the form/field.
