Pro Var Warning with textarea type variable

[benoitlemay]

I have a PHP warning

When i use 2 instances of a single tag of Pro Var..
ex.: I have {exp:pro_variables:single var="adresse" formatting="xhtml" html="all"} in my template AND in my main_layout.
adresse var is a textarea type and i need the html formatting, i got the Warning

If i use the tag pair it works without Warning.. ex.: {exp:pro_variables:pair var="adresse" formatting="xhtml" html="all"}{adresse} {/exp:pro_variables:pair}
