To have a better controle on script you can implement like me your own
DocumentScriptBuilderImpl
And override the existing with this code in your app module :
public PageRenderInitializer buildMyPageRenderInitializer(final
List<PageRenderCommand> configuration,
final
Environment environment) {
return new PageRenderInitializer() {
public void cleanup(MarkupWriter writer) {
Iterator<PageRenderCommand> i =
InternalUtils.reverseIterator(configuration);
while (i.hasNext())
i.next().cleanup(environment);
environment.clear();
}
public void setup(MarkupWriter writer) {
environment.clear();
environment.push(MarkupWriter.class, writer);
environment.push(Document.class, writer.getDocument());
for (PageRenderCommand command : configuration)
command.setup(environment);
}
};
}
public void
contributeMyPageRenderInitializer(OrderedConfiguration<PageRenderCommand>
configuration,
ThreadLocale threadLocale,
@Path("org/apache/tapestry/default.css")
Asset tapestry_css,
@Path("my_own.css")
Asset my_own_css,
@Path("org/apache/tapestry/field-error-marker.png")Asset fieldErrorIcon,
ValidationMessagesSource
validationMessagesSource,
final SymbolSource
symbolSource,
final AssetSource
assetSource) {
configuration.add("PageRenderSupport", new PageRenderCommand() {
public void cleanup(Environment environment) {
environment.pop(PageRenderSupport.class);
Document document = environment.peek(Document.class);
DocumentScriptBuilder builder = environment.pop(
DocumentScriptBuilder.class);
builder.updateDocument(document);
}
public void setup(Environment environment) {
DocumentScriptBuilder builder = new
MyOwnDocumentScriptBuilderImpl();
environment.push(DocumentScriptBuilder.class, builder);
environment.push(PageRenderSupport.class, new
PageRenderSupportImpl(builder,
symbolSource, assetSource));
}
});
configuration.add("Heartbeat", new PageRenderCommand() {
public void cleanup(Environment environment) {
environment.pop(Heartbeat.class).end();
}
public void setup(Environment environment) {
HeartbeatImpl heartbeat = new HeartbeatImpl();
heartbeat.begin();
environment.push(Heartbeat.class, heartbeat);
}
});
configuration.add("InjectTapestryStylesheet", new
InjectStandardStylesheetCommand(tapestry_css));
configuration.add("InjectBaseStylesheet", new
InjectStandardStylesheetCommand(my_own_css,));
configuration.add("DefaultValidationDelegate", new
DefaultValidationDelegateCommand(threadLocale, validationMessagesSource,
fieldErrorIcon));
}
public static void
contributeAliasOverrides(Configuration<AliasContribution> configuration,
@InjectService("MyPageRenderInitializer")PageRenderInitializer
pageRenderInitializer) {
configuration.add(AliasContribution.create(
PageRenderInitializer.class, pageRenderInitializer));
}
And you can controle the script render like this (in your own
DocumentScriptBuilderImpl)
public void updateDocument(Document document) {
Element head = document.find("html/head");
Element body = document.find("html/body");
if (head == null || body == null)
return;
for (int i = 0; i < scripts.size(); i++) {
String scriptURL = scripts.get(i);
head.elementAt(i, "script", "src", scriptURL, "type",
"text/javascript");
}
if (scriptBlock.length() > 0)
{
...
}

Thanks! These both work, sort of. The renderSupport puts the script
tag in the body tag (5.0.5). So, its not a huge improvement. While the
more manual solution of adding the element works well enough, neither
of these solutions easily allow arbitrary blocks to be inserted. I
think this would be the holy grail of this situation.
1. Define a Block of code (declaratively in your template)
2. Insert Block into head
With the Element and RenderSupport solutions I imagine the the
plumbing exists to do this. I'll have to dig deeper into the how's to
figure it out.
Thanks again.
