html:checkbox default value

[Erez Efrati]

I am trying to set the default value of a checkbox to 'checked' by
putting:
<html:checkbox property="schedule" value="true"/>
 
but somehow it does not check it. The produced HTML gives me 
 
<input type="checkbox" .. value="on" > 
 
What am I missing here?
 
Thanks,
 
Erez
