Hi,
All the examples including yours seem to work like this
if the code snippet checked for the description first then
If product A has a description then it shows a description
If product B has a long_description then it shows nothing.
If you then swap the code so that it checks for long_description first then
If product A has a description then it shows nothing
If product B has a long_description then it shows the long_description.
${productContentWrapper} just shows
org.ofbiz.product.product.ProductContentWrapper@6ec0ac92
Thanks
Sam
