[rules-users] Missing space when using DSL and Guvnor

I am setting up a very simple example using a DSL and Guvnor. My DSL is as follows: [when]Age is less than {age} years old=AgeFact(ageInYears < {age}) When I attempt to create a new Business Rule using the Guvnor I can select the above expression just fine and the sentence displays as expected. I then fill in the years with a numeric value (4) and validate. Upon validation I receive the following error. [Age Test Rule] [ERR 101] Line 4:2 no viable alternative at input 'Age' in rule "Age Test Rule" I then view the source and it looks like this. rule "Age Test Rule" dialect "mvel" when Age is less than 4years old then end I noticed that there is no space between the '4' and the word 'years'. However, in my DSL sentence there is a space between {age} and years. Another interesting thing, if I enter the number 4 followed by a space in the Guvnor form then the rule validates correctly. Is this a bug or is it something I am doing wrong in my DSL?
