Hi,
Thank you. I know, I realized I made a typo. It should be:
@Property
Object tempValue
<t:loop source=“countries” value=“tempValue”>
${tempValue.getName(locale)} - ${getPopulation(tempValue)}
</t:loop>
I think var prefix is a great addition, but it should be able to use var in
property expression, and not only as single read write property storage.
