Just an FYI,
Inspecting jumpstart, and the component rendering page, I couldn't get
@BeforeRenderBody to fire.
@BeforeRenderTemplate
boolean beforeRenderTemplate(MarkupWriter writer){
Element cur = writer.element("div",
"class","userbackground").addClassName("adifferentbackground");
cur.text("CHRIS! This is your amazing test div -
beforeRenderTemplate");
writer.end();
return true ;
}
@BeforeRenderBody
void beforeRenderBody(MarkupWriter writer){
Element cur = writer.element("div",
"class","userbackground").addClassName("adifferentbackground");
cur.text("CHRIS! This is your amazing test div -
beforeRenderBody");
writer.end();
}
The component rendering page says "...Generally, your code will use the
SetupRender, BeginRender, AfterRender and CleanupRender phases ... often just
one or two of those..." which I'm happy with.
Is the diagram accurate as to this @BeforeRenderBody annotation? For my case,
I'm happy to use beginRender - I just can't seem to follow the flow to get
@BeforeRenderBody to do what is suggested on
https://wiki.apache.org/tapestry/Tapestry5HowToCreateYourOwnComponents for the
tree example.
Cheers
