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

Example 1 with ComponentPageElement

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

the class AjaxComponentInstanceEventResultProcessor method processResultValue.

public void processResultValue(Component value) throws IOException {
    ComponentResources resources = value.getComponentResources();
    boolean isPage = value == resources.getPage();
    String pageName = resources.getPageName();

        // This will ultimately send a JSON response to redirect to the page
        masterProcessor.processResultValue(pageName);
        return;
    }
    // Otherwise, a component within a page. Components are transformed to implement RenderCommand, but if we just
    // pass the component itself to the master processor, we'll get in a loop, so we instead
    // pass the ComponentPageElement (which implements RenderCommand as well).
    Page page = cache.get(pageName);
    String nestedId = resources.getNestedId();
    RenderCommand command = page.getComponentElementByNestedId(nestedId);
