[Bioc-devel] Help with class lost after subsetting.

Dear Bioconductor developers,

In the CAGEr package, I created a "CAGEexp" class that extends
"MultiAssayExperiment" without adding new slots, in order to define generic
functions that require CAGEr-specific contents in the colData slot.

Unfortunately, when run in the development branch of Bioconductor,
the CAGEexp objects lose their class when they are subsetted.  Here
is an example:

CAGEr::exampleCAGEexp

A CAGEexp object of 4 listed
(...)

CAGEr::exampleCAGEexp[,1]

A MultiAssayExperiment object of 4 listed
(...)

This breaks examples in the package, as well as existing code.

I am lost on how to troubleshoot this.  May I ask for your help ?

Best regards,
