> There is DSL file with next content:
> [when] There is a {type} named {name} = {name} : {type}() 
> [when] - {prop} is {val} = {prop} == {val}
> And DRL which uses this DSL:
> package prototype
> import com.test.types.ClientServiceTypeType;
> import com.test.ClientService;
> expander ValidationCasesPrototype.dsl
> rule "Bug with dot reduction"
> 	when
> 		There is a ClientService named cs
> 		- type is ClientServiceTypeType.GOLD
> 	then 
> 		# Then part
> end
> ClientServiceTypeType.GOLD is a public static final ClientServiceTypeType field.

> It seems that substitution for variables in DSL works incorrectly and simply ignores ".". Quick workaround is to use "\" before dot. In that case rules are loaded correctly.
> Same code worked in version 3.0.6.
