View Data Issue

$a was set with the first view load.  Data passed to any view is cached and is available to any subsequent views that are loaded.

I want to ask a question:

First model loads view with data.

And then model loads another model.

Second model loads previous view again with another data without clear.

What happens at this time?

All data stays, but the newer pieces overwrite older ones.

Hmm. I think there must be a fourth parameter for cache these variables. I have checked previously discussed messages in Github. These caching mechanism is good but user may set this option. May be with config parameter... With this type, it can generate a security hole in complex structures.

Of course; i learned why this happens and what i must do if i want to load same view again. Thx

If i write something by mistake; please don't distress it and try to understand what i want to write.
