anonymous wrote : 15.2. Annotations for bijection
|
| The next two annotations control bijection. These attributes occur on
component instance variables or property accessor methods.
|
| @In
|
| @In
|
| Specifies that a component attribute is to be injected from a context
variable at the beginning of each component invocation. If the context variable
is null, an exception will be thrown.
|
| @In(required=false)
|
| Specifies that a component attribute is to be injected from a context
variable at the beginning of each component invocation. The context variable
may be null.
|
| @In(create=true)
|
| Specifies that a component attribute is to be injected from a context
variable at the beginning of each component invocation. If the context variable
is null, an instance of the component is instantiated by Seam.
|
| @In(value="contextVariableName")
|
| Specifies the name of the context variable explicitly, instead of using
the annotated instance variable name.
|
| @In(value="#{customer.addresses['shipping']}")
|
| Specifies that a component attribute is to be injected by evaluating a
JSF EL expression at the beginning of each component invocation.
|
| *
|
| value ? specifies the name of the context variable. Default to
the name of the component attribute. Alternatively, specifies a JSF EL
expression, surrounded by #{...}.
| *
|
| create ? specifies that Seam should instantiate the component
with the same name as the context variable if the context variable is undefined
(null) in all contexts. Default to false.
| *
|
| required ? specifies Seam should throw an exception if the
context variable is undefined in all contexts.
Where in this documentation is it stated that @In(create=true) results in
looking up a reference to an EJB from JNDI? Maybe when create=true, and no
instance of the named component (EJB) is available is any scope, then Seam
takes that as a cue to look up the component (EJB) from JNDI - that's fine with
me, I think that behavior should be explicitly added to the documentation; and
add an example of this. I looked carefully through the documentation before
posting this question ... so how do your responses help with understanding my
initial issue or answer the questions subsequently posed?
