Title: A fix for the direct access of isa

This is a fix for isa is deprecated warning.
isa direct access has been deprecated, and as a conclusion we will not be able to use this function in the next releases.
We can argue weather it is right or wrong but the fact is that it is deprecated.
So, this is the fix.
