Hi,

Do you have any user permissions set? It is possible that something is 
not permitting you to see it. In that case this might be a bug, because 
there is a way to get around it.

In the next Drools release the asset should also be visible in archives 
after you have archived the package.

can you look in the error logs? I was really hoping to CR1 over the
