Hi, I use a package builder to build rule packages loaded from a DB. Those rules are written in a dsl so I use also a dsl file. But I'm looking for a simply way to return the line number if there is a parsing error. In fact I need something like DroolsError.getLine(). how can I do this Thank's -- View this message in context: http://www.nabble.com/find-the-error-line-number-in-a-rule-tf4273189.html...
