Re: [rules-users] rules not wrking
by John Peterson
If you really wanted to see your text string there, you might be able to
invoke a method that takes that text string and prints it and then
returns "true" in all cases. You'd most likely need to put it in an
Eval as suggested below.

Missing space when using DSL and Guvnor
by Doyel,Jeff
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
