Have a t-on within a t-foreach
the t-on has an expression
Before this commit, when triggering the t-on, the expression was falsely evaluated
In details, the expression took scope from outside the foreach loop
as we protect it to have similar results than an actual for loop
But, at triggering time, the scope protection had already been terminated
meaning the info of the iteration of the loop the handler has been built in
had already disappeared
This commit fixes that
closes#594
Before this commit, the handlers were bound to the current context,
which is often the component but not necessarily. In some cases, a sub
scope can be created (with t-foreach, or slots, or t-call), and the
context is actually an object with the actual component instance it its
prototype chain, but not the component.
This commit is a significant refactoring of the internal of QWeb. It
simplifies the way variables/scoping and slots interact together. The
main idea is that we use a simple scope object instead of a
context/var/scope object.
This commit also implement the actual correct QWeb semantic for the
t-call directive with a sub body. Before, we simply extracted the
variables from the body and injected them at the top of the sub
template. We now simply compile the body before the sub template.
This is a joint work with Lucas (lpe).
