[rules-users] Creating a RuleFlow in eclipse

Could someone tell me how to use the RuleFlow editor in Eclipse? I've created a .rf file and I have a Start node. Next I add a Split node followed by 2 RuleFlow nodes. I select the 'connection' tool, click the Split node and draw a line to my 1st RuleFlow node. I go back to the Split node and try to draw a connection line to my 2nd RuleFlow node but it won't let me. When I click the Split node it gives me a circle with a line thru it (which I'm interpreting as meaning "not allowed"). I can't make a connection between my Start node and my Split node either. What am I doing wrong? Why can't I draw more than 1 connection line? Also, the connection line that I can draw does not have the arrow, indicating direction, at the end of the line like all the examples I've seen do. Is that a problem? Any help would be appreciated. Thanks, Rod
