Hi Kris,
Thanks,
I'm nearly there but not yet complete. In my component I'm able to build
a FieldValidator but I cannot get it to use the @Validate annotation
from the containing class (actually a page).
So what I want is this (pseudo code)
SomePage {
@Component(id="someId")
@Validate("required") <----- how can I use this annotation from my
component??
private MyComponent myComponent;
}
MyComponent {
@Parameter(defaultPrefix = BindingConstants.VALIDATE)
@Property
private FieldValidator<?> fieldValidator;
@Component(id = "field", parameters =
{"validate=prop:fieldValidator"})
private TextField field;
}
When I build the FieldValidator I need to give it a AnnotationProvider
that is going to 'find' the @Validate annotation but how can I get
access to the @Validate annotation from the parent (ie the page)?
As a workaround I have created a FieldValidator builder that builds a
FieldValidator using a string so I can set the validator in my page
like:
SomePage {
@Component(id="someId", parameters =
{"validate=required,minlength=4"})
private MyComponent myComponent;
}
But that's a bit clumsy.
Any idea?
