Thank you for your answer. You have confirmed what I was thinking about. Fortunatelly, I had a look in xsource and found the source code of builder.app (the one called from right-click). Interesting. That app checks if the object passed to it have a property named "Builder". If that property exists and it have a fullpath to a prg, that prg is executed with rigth click.
So, no need anymore to check the class and register the builder. I'll create just a .Builder property and write the full path to my builder in it. Works for no matter how many subclasses (assuming they have the same info there).
Thank you so much.
