For a "trigger build in another configuration" step, the "Propogate variables to dependent builds?" option is not presented on the page. Looking at the demo environment, the option was available in the 1.1.0 (build 1) release

As a result, variables from the triggering configuration can not be forwarded to the dependent configuration.

In the triggering configuration, I set up the following in the "Override variables" text area:

sourceBuildVersion=${build.version}


and tried to access the variable in an Ant builder in the dependent configuration as
     
buildVersion=${sourceBuildVersion}

the following error occurs in the dependent configuration when it is triggered

java.lang.RuntimeException: ognl.NoSuchPropertyException: com.pmease.quickbuild.model.Configuration.sourceBuildVersion

Should this work
