We use html templates extensively and set the tabindex for the fields within the HTML (this is an amended form form tms.webcore\Demos\Basics\HTMLTemplate) :
<input type="TEXT" id="edt" tabindex=1>
<input type="DATE" id="dat" tabindex=2>
<button type="BUTTON" id="btn" tabindex=3>Add</button>
All works well except for TWebDateTimePicker which always sets the tabindex to 0, but does add step=1

Is there a workaround for this or do I need to set up a bug fix request?
Attached is the amended demo project.
