InjectComponent Field in component and validate field in page class

I have a component that contains a field like so,

Vendor.class

@InjectComponent
@Parameter
private Field vendorName;

I have a page class like so,

Page.class

@Property
private Field vendorName;

onValidateFromForm() {

//I would like to do some serverside validation and return the error back
to the field, but I'm not sure how to connect the field in the component
with the page class.

    if(condition == true) {
        form.recordError(vendorName, "some error message");
    }

}

Page.tml

<t:vendor vendorName="vendorName"/>

Anybody know if it's possible to connect the fields like this. Thanks

You can add getter for injected field inside vendor component:

Vendor.class

@InjectComponent
private Field vendorNameField;

public Field getVendorNameField() {
   return vendorNameField;
}

Then inject vendor component inside the page

Page.class

@InjectComponent
private Vendor vendor;

void onValidateFromForm()  {
    if(condition == true) {
        form.recordError(vendor.getVendorNameField(), "some error message");
    }
}

Don't forget to use t:id attributes on injected components.
