Thanks again for your prompt reply.
You're right: Context.Count works inside the repeating element, but it
does not help in the cases that do not have entries.
I've tried <span if="${!gifts.content}">...</span>, but the message
is not shown.
${gifts.content} alone is evalued to []
${!gifts.content} returns nothing
${gifts.content == []} returns nothing
Would you have any other suggestions? :-)
