[antlr-interest] Warning. Signature has changed.

[Joan Pujol]

I have a tree parser that extends another:

P2 extends P1

In P2 I have:
decvariable: #(DECVARIABLE IDENTIFICADOR IDENTIFICADOR (expressio)?);

and in P1:
decvariable returns [boolean error=false]: #(DECVARIABLE
nom:IDENTIFICADOR nomtipus:IDENTIFICADOR (expressio)?)

(I have added a return value)

ANTLR gives me this warning:
      warning: rule P2.decvariable has different signature than
AnalitzadorBaseAST.decvariable

Can I ignore this warning or this warning have some consequences I need to know?
