Foglight Evolve 9.3 - Web Component Guide

agent = <host>/agent, where host is an object that has a property called agent.

This is also useful if you are building a container view and want to include children that require particular keys that are not explicitly present. Example: the child view has a key called host, but your parent view uses selectedHost. Solution: in additional context, map host to selectedHost. This section needs work. Find out what “a particular child of an existing context key” is, and what is meant by keys that are not explicitly present. The text above comes from the Wiki.

Table 13. Additional context parameters for a view
Additional Context for a view consists of:
Key	The key used to reference the object in other dialog boxes or scripts.
Name	A more descriptive name for the key.
Evaluate Once	A Boolean value. If this check box is cleared, the key is evaluated each time the page is rendered. This is useful if the key is set to a binding whose value changes dynamically. If the box is checked, the key is evaluated when the page is created, but never after that. This is useful if the key is set to a static value or if reevaluating the key would cause errors. For example, if the key is used to create a new writable data object that should persist across multiple references to the page. If Evaluate Once is false, a new writable data object would be created each time the page is referenced.
Value	The value is set using the binding editor. It can be a static value or a binding.

When adding a view to a container view, it sometimes happens that the available context does not have the right information for the view that you want to include. In this case, it is possible in the container view to selectively create the right context. This is called additional context for an instance or instance context. The context is for that particular instance of the view and is not available when you use the view somewhere else. It would be more useful to show where to set the additional context, and to give an illustrative example.

Table 14. Additional context parameters for an instance
Additional Context for an instance consists of:
key	The strongly typed, case insensitive string that references a particular context element. Type checking is done at design time.
value	The value stored in the context element, which can be either a static value or a binding.


	NOTE: You would create the additional context of the view itself if you wanted it available to every instance of the view.
