Chained assignment of mock service fails to compile #161

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
In a Spec extending grails.plugin.spock.ControllerSpec, attempt to chain 
assignment of a Mock() to the controller field and then a local variable.

eg
    AccountService accountService = controller.accountService = Mock()

This gives a Spock compilation failure.  The stack trace is below.

The equivalent statements
    AccountService accountService = Mock()
    controller.accountService = accountService
work correctly.

This is using the spock-0.5-groovy-1.7-SNAPSHOT plugin with the geb-0.4 plugin 
and Grails 1.3.5, which uses groovy 1.7.5.

Stack trace:
Unexpected error during compilation of spec 'app.TransactionControllerSpec'. 
Maybe you have used invalid Spock syntax? Anyway, please file a bug report at 
http://issues.spockframework.org.
