Subject: ^ binding syntax usage
Hi there,
anyone remember when the '^' was introduced for component bindings and
where the official docs are for it?
I'm obviously a little rusty on its usage as I can't make it work.
e.g.,
MainWrapper.wo:
<...>
<head>
<wo:string value="$^title"/>
</head>
Main.wo:
<wo:MainWrapper title="Foo bar">
<...>
</wo:MainWrapper>
UnknownKeyException: [<com.webobjects.appserver.WOComponent name:
MainWrapper subcomponents: null > takeValueForKey()]: attempt to assign
value to unknown key: 'title'. This WOComponent does not have an instance
variable of the name title or _title, nor a method of the name setTitle or
_setTitle
public class MainWrapper.java extends ERXStatelessComponent {...}
public class Main.java extends ERXNonSynchronizingComponent {...}
What am I missing?
with regards,
-
