The query and sort fields take luan tables entered as text.
Hugo, please review the HTML of the tools in the jeans project. The best way to work on this is to change your classpath to use the luan source directly instead of using the luan jars. For the luan source classpath, see luan/dist/scripts/luan-dev-classpath.sh .
I ran build-luan.sh successfully, but the new jar files don't work with my jeans project. I get errors when I start jetty. I don't want to changing my classpath to point to the luan source. I prefer working with the JAR files.
