[rules-users] Guided DRL editor

Hello, I am new to JBoss rules and was wondering if someone could explain how to get started with the new Guided DRL Editor. I'm using Drools 4.0 and the Eclipse IDE. I've clicked on 'New Guided DRL editor' in Eclipse and it's created the rules.brxml file. The editor is on the screen showing 'If', 'Then', and 'Options' but it's blank. I've selected the 'If' and clicked on little screen with the '+' on the right side of the editor. A dialog box opens with 'Add a New Condition' and a drop down box for 'Fact' but the only option in the drop down box is 'Choose a Fact'. I've also selected 'Then' and clicked on little screen with the '+' on the right side of the editor. A dialog box opens with 'Add a New Action' and several drop down boxes. The only option in all of the drop down boxes is 'Choose'. How do I get these boxes populated? I've already got several existing rules coded and I thought they would show up in the editor but they don't. Do I have to code the rules in Java before I can use the editor? According to what I've read, this is supposed to be a point-and-click way of creating rules but so far I haven't seen that. I was hoping to be able to use the editor as sort of a gui for creating or modifying my rules but haven't been able to figure out how to do that. Any help would be appreciated. Rod
