Examples with ComponentPageElement org.apache.tapestry5.internal.structure.ComponentPageElement used on opensource projects

Example 16 with ComponentPageElement

use of org.apache.tapestry5.internal.structure.ComponentPageElement 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);
}

Example 17 with ComponentPageElement

use of org.apache.tapestry5.internal.structure.ComponentPageElement in project tapestry-5 by apache.

the class PageLoaderImpl method copyInformalParameters.

private void copyInformalParameters(ComponentPageElement container, ComponentPageElement embedded) {
    // TODO: Much more, this is an area where we can make things a bit more efficient by tracking
    // what has and hasn't been bound in the EmbeddedComponentAssembler (and identifying what is
    // and isn't informal).
    ComponentModel model = embedded.getComponentResources().getComponentModel();
    Map<String, Binding> informals = container.getInformalParameterBindings();
