Example 2 with Environmental

use of org.apache.tapestry5.annotations.Environmental in project tapestry-5 by apache.

the class FormFragment method beginRender.

/**
 * Renders a <div> tag and provides an override of the {@link org.apache.tapestry5.services.FormSupport}

    componentActions = new ComponentActionSink(logger, clientDataEncoder);
    // Here's the magic of environmentals ... we can create a wrapper around
    // the normal FormSupport environmental that intercepts some of the behavior.
    // Here we're setting aside all the actions inside the FormFragment so that we
    // can control whether those actions occur when the form is submitted.

    // Tada! Now all the enclosed components will use our override of FormSupport,
    // until we pop it off.
    environment.push(FormSupport.class, override);
}
