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

[Paul R.]

Hi Jeff,

I logged a bug for this one a while back, here's the JIRA, patch details
included.

https://jira.jboss.org/jira/browse/GUVNOR-520

I would appreciate it if somebody could commit this for me :)

Cheers,

Paul

>>  I am setting up a very simple example using a DSL and Guvnor.  My DSL is

>>
>> [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?
