External References tab
An external reference makes the value of a local tag, controller tag, or tag member within a library object accessible to parameters in other library objects. Used in conjunction with parameters that have been assigned to accept values by reference, external references provide the points of contact between library objects in an
Application Code Manager
project.External references are listed alphabetically. They are grouped based on the value in the
Name
field for the external reference.In an
Application Code Manager
project, link an external reference to a reference-type parameter. The parameter references the value of the external reference when the project is in operation. Reference-type parameters are defined so that the external references that are accessible to them are limited to those that meet certain criteria (filters).- Any tag or tag member can be added as an external reference.
- An external reference can be copied to other library objects and to library objects of different scope.IMPORTANT:Check that the library object contains the referenced Tag before copying and pasting an External Reference.
- External references are not available to theExpression Builder.
