[rules-users] DSL not working on 3.1 M1

Hi, I dont know if this is for User or for developer list, but I'm having problems with dsl expanders on drl file. Using 3.1 M1 plugin and 3.1 M1 core (all with deps) a simple example using a .dsl expander file compile and fire rules, but doesnt activate any. The same example not using expander works fine (I have to put the drl code on drl file and comment the expander line on the drl file). Its seems that the expander is not working properly. Changing the project classpath to use 3.0.6 libs makes all works fine, the problem is I need to use some functionality I think is just working on 3.1. Thx.
