It sounds like a bug. Can you double check it and create a jira issue please?

best,

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?

 

Thanks,

Jeff
