Error message needed when parent module is not correct about mvp4g HOT 4 CLOSED

Attached is a patch that eliminates this problem by adding a setParentModule 
method to 
the Mvp4gModule interface. The parameter is a Mvp4gModule which is casted back 
to the 
proper type in child module method definition. Rather than using the parameter 
to 
determine the parent module type, it is saved into ChildModuleElement when they 
are 
loaded.

Thanks for the patch.

I have a question about your correction. For a child module, in 
Mvp4gConfiguration.java, findParentModule will always return null since a child 
module won't have an annotation @ChildModule with its class. Then you won't 
have 
access to parent module & parent event bus classes and won't be able to do the 
right 
cast. Am I missing something?

Indeed you are correct. I guess it was a bit too late to be coding... Anyway I 
have 
attached a patch that should be correct. This patch finds the parent type by 
searching 
through the annotation scan results for a class annotated with @ChildModules 
containing 
the module in question.
