I apologize for my ignorance, but I am kind of confused about how the render
phases work.
Simple example:
class Base{
@SetupRender
protected boolean setupRender(MarkupWriter writer) {
//do something
}
}
class Derived extends Base{
@BeginRender
protected void beginRender() {
//do something
}
}
class AppModule{
public static PageResponseRenderer decoratePageResponseRenderer (){
return new PageResponseRenderer() {
public void renderPageResponse(Page page) throws IOException {
//do something
((PageResponseRenderer)
delegate).renderPageResponse(page);
}
}
}
}
Request comes in to Derived:
Expected:
Base(SetupRender)->Derived(BeginRender)->AppModule(renderPageResponse)
Actual:
Derived(BeginRender)->AppModule(renderPageResponse)->Base(SetupRender)
How come setupRender is being called from renderPageResponse and not right
at the beginning when the request comes in? According to the docs at
http://tapestry.apache.org/tapestry5.1/guide/rendering.html, SetupRender
should happen right upfront.
Could someone please shed some light? I am still learning.
