Bug caused by the use of the `||` operator to replace all non-truthy
values with an empty string. Changed to replace only `undefined` values.
Closes#1401
previously we expected to find option elements only within select element and if
that was not the case we throw an error. This made it impossible to include datalist
element with nested option elements in the template.
Closes#1165
we now have two types of namespaces:
- true namespace: angular.* - used for all global apis
- virtual namespace: ng.*, ngMock.*, ... - used for all DI modules
the virual namespaces have services under the second namespace level (e.g. ng.)
and filters and directives prefixed with filter: and directive: respectively
(e.g. ng.filter:orderBy, ng.directive:ngRepeat)
this simplifies urls and makes them a lot shorter while still avoiding name collisions
Previously only when ngOptions was used, we correctly handled situations
when model was set to an unknown value. With this change, we'll add/remove
extra unknown option or reuse an existing empty option (option with value
set to "") when model is undefined.
