Example 8 with Mixin

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

Example 9 with Mixin

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

the class PageLoaderImpl method connectInheritedParameter.

private void connectInheritedParameter(ComponentPageElement container, ComponentPageElement embedded, String parameterName, String containerParameterName) {
    // TODO: This assumes that the two parameters are both on the core component and not on
    // a mixin. I think this could be improved with more static analysis.
    Binding containerBinding = container.getBinding(containerParameterName);
    if (containerBinding == null)
        return;
    // This helps with debugging, and re-orients any thrown exceptions
    // to the location of the inherited binding, rather than the container component's
    // binding.
    // Binding inherited = new InheritedBinding(description, containerBinding, embedded.getLocation());
    embedded.bindParameter(parameterName, containerBinding);
