Hi Guys, As far as I know the drools parser will parse the .dsl file content starting from the 1st line going toward the last one. So the order we follow to specify the "Language expression" does matter! The problem is that the DSL Editor in eclipse does not allow us to rank the dsl sentences we define. It just fill the .dsl file following the insertion order. Once we have defined a new sentence we can't do anything to change the order. If we want to change the order we have to open "manually" the file and manage ourselves the .dsl content. Is there any workaround to this? Will u fix it? Massi
