Hi George,
The problem is with the "component:shiptoContactName" piece of the expression.
Specifying the property prefix (eg: prop:, component:, validate:, etc.) only
works at the beginning of the expression, and it is applied to the entire
expression.
The thing to do in this case is:
.tml:
<t:textfield ... t:validate="prop:getFieldValidator(shipttoContactName)"/>
.java:
@InjectComponent
@Property
private TextField shiptoContactName;
Now you've injected the component into the page class and made it a property of
the class, so you can reference it directly in the property expression.
Cheers,
Robert
