Alejandro Ramirez reopened BEEHIVE-812:
---------------------------------------
Rich, when verifying this bug, I don't get an error when hitting the begin
action. However, I get an error (see attached log) when submitting the form.
ERROR ExpressionEvaluatorImpl []: Exception when attempting to update the
expression "{actionForm.foo}" with available binding contexts [actionForm,
pageFlow, globalApp]. Root cause: java.lang.RuntimeException: Can not update
the identifier "foo" on a null value object.
Throwable: java.lang.RuntimeException: Can not update the identifier "foo" on a
null value object.
> Cannot provide an initial value for an action that accepts an interface as
> its form bean

> We have an action method that accepts an *interface* as its form bean
> argument, and we're trying to send a concrete implementation of the interface
> to a page that will post to the action.
> Repro:

> EXPECTED: See index.jsp with the text box initialized to the string, "got it"
> ACTUAL: A tag error that says:
> Caught exception when evaluating expression "{actionForm.foo}" with
> available binding contexts [actionForm, pageFlow, globalApp, request,
> session, application, pageContext, bundle, container, url, pageInput]. Root
> cause: java.lang.RuntimeException: Can not evaluate the identifier "foo" on a
> null value object.
