Guys,
I am whipping up a simple Login page... no *.page files just annotations.
The page displays and the validators are nice.
If someone could bail me out here I would be greatful. The Login.html quits
on trying to render the OGNL for emailAddress.
OGNL is having trouble getting to this object (Person object persisted and
created during onrender)
I am kinda blue in the face...
Do you see anything in my code preventing the html from retrieving this
property?
What am I missing? Thanks so much.
Here is the exception...
org.apache.tapestry.BindingException
Unable to read OGNL expression '<parsed OGNL expression>' of
[EMAIL PROTECTED]: $BasePage_4.emailAddress
binding: ExpressionBinding[Login emailAddress]
Thanks in advance
