Re: update a zone from within a component
Indeed, that would do the trick just nicely. I was thinking way too complicated, thanks Igor.

The zone should update itself with it's own content and that's the problem. Inside the component I don't have direct access to the Zone on the page. Passing the Zone as a parameter to the component works but calling getBody() on it returns nothing it seems. I now have to use ComponentSource to locate the zone in the page and then I can return it's body from the event handler mehtod. That works but is ugly.

Re: Audit logging - how to acces SSO in Hibernate
What i am doing is to contribute a PageRenderRequestHandler like this:
public static void
contributePageRenderRequestHandler(OrderedConfiguration
configuration,
final @Local
@InjectService("securityContextPageRenderRequestFilter")
PageRenderRequestFilter securityContextPageRenderRequestFilter) {
configuration.add("securityContext",
securityContextPageRenderRequestFilter, "after:*");
}
I am using Chenillekit's access component:
(http://www.chenillekit.org/chenillekit-access/index.html) so in the
filter i get the WebSessionUser using the ApplicationStateManager.
Here u should get the object from the session. Just be sure that the
filter is executed after the WebSessionUser is put into the session.
the filter look like this:
public class SecurityContextPageRenderRequestFilter implements
PageRenderRequestFilter {
private final ApplicationStateManager _manager;
private final Logger _logger;
/**
* @param manager
* @author jmayaalv
*/
public SecurityContextPageRenderRequestFilter(ApplicationStateManager
manager, Logger logger) {
super();
_manager = manager;
_logger = logger;
}
public void handle(PageRenderRequestParameters parameters,
PageRenderRequestHandler handler) throws IOException {
RincoSessionUser webSessionUser = (RincoSessionUser)
_manager.getIfExists(WebSessionUser.class);
if (webSessionUser != null) {
SecurityContext securityContext = new
SecurityContext(webSessionUser.getUserId());
SecurityContextHolder.set(securityContext);
_logger.debug("SecurityContext added to the thread {}
", new
Object[] { securityContext });
}
handler.handle(parameters);
}
}
SecurityContextHolder is the class that interacts with threadlocal:
public class SecurityContextHolder {
private static ThreadLocal tLocal = new
ThreadLocal();
public static void set(SecurityContext securityContext) {
tLocal.set(securityContext);
}
public static SecurityContext get() {
return tLocal.get();
}
public static void remove() {
tLocal.remove();
}
}
U can get the SecurityContext during the thread execution with:
SecurityContextHolder.get()
Let me know if u need something else

Ok, I think I get the idea... But where and when do you set the ThreadLocal? It must be set on every request (each request is another thread...) Do you have a common base class where you handle this?

it appears that with T5 I am not completely shielded from JavaScript

I can do this in pure Java?) if I want to do AJAX. The specific

From the forums, I have gathered that I must use the Chenille Kit

where to
put this code (in Java file or tml file or some other js file) and
then how
to tie these things together. In the T5 help documentation, there is
some

not

So my question is simple: where should this code be located and how

added - such
as RenderSupport (and where)?

Re: T4.1: rendering a page to alternate OutputStream
Mine is rather long owning to having it create a PDF. In short, I
don't use PageRenderSupport since you don't really need it and it's
likely usable only by pages, which this isn't. In my case, I'm filling
in a form then flattening it (removing the forms, but leaving the
filled in data.) Using iText, I get a Reader (which reads PDFs) and
then create a Stamper that writes them, and it uses a FileOutputStream
to send the data.
If your lib can't use a FileOutputStream, create an
ByteArrayOutputStream or copy from a local file (I do that as well for
PDFs that just stream out as-is.)
Here is an excerpted part:
public class PDFExport implements IEngineService {
public static final String MIME_TYPE = "application/pdf";
private WebResponse response;
private LinkFactory linkFactory;
private HttpServletRequest request;
public PDFExport() {
}
public PDFExport(MapMailbox inMailbox) {
mailbox = inMailbox;
}
public WebResponse getResponse() {
return response;
}
public void setResponse(WebResponse response) {
this.response = response;
}
public LinkFactory getLinkFactory() {
return linkFactory;
}
public void setLinkFactory(LinkFactory linkFactory) {
this.linkFactory = linkFactory;
}
public HttpServletRequest getRequest() {
return request;
}
public void setRequest(HttpServletRequest request) {
this.request = request;
}
@Override
public void service(IRequestCycle cycle) throws IOException {
WebResponse w = getResponse();
ContentType ct = new ContentType(MIME_TYPE);
String formIdParam = cycle.getParameter("formId");
// Set special headers to work around a bug in IE with https.
w.setHeader("Cache-Control", "max-age=0");
w.setHeader("Pragma", "public");
Integer formId = Integer.parseInt(formIdParam);
Form f = FormManager.getForms(true).get(formId);
// Set the file name of the exported file.
w.setHeader("Content-Disposition", "inline; attachment; filename=" +
f.getFileName());
Map baseFieldMap =
FormManager.getFieldMap(getMailbox(), f);
servicePdf(f, baseFieldMap, w.getOutputStream(ct));
}
/**
* Output a dynamically modified PDF form.
*
* @param f The form to output.
* @param baseFieldMap The data to put on the form.
* @param theOutStream The stream to output the form to.

public void servicePdf(Form f, Map baseFieldMap,
OutputStream theOutStream) throws IOException {
// Set up an output stream
OutputStream webOut = theOutStream;

reader = new PdfReader(fis);

Re: update a zone from within a component
That's not what I was asking for. Maybe I was a bit unclear. Triggering the update itself is not the problem but returning the correct content for updating the zone from the event handler method of the component. The zone should update itself with it's own content and that's the problem. Inside the component I don't have direct access to the Zone on the page. Passing the Zone as a parameter to the component works but calling getBody() on it returns nothing it seems. I now have to use ComponentSource to locate the zone in the page and then I can return it's body from the event handler mehtod. That works but is ugly.

I will try this, but this is not relevant to the issue in question, which is
how to control the ordering of eagerloaded services. The very need to eagerload
a service already implies that order is important, not being able to imho is an
oversight.

The is a database connection pool that has all the relevant synchronization
semantics in place, I agree that pure IoC would be better but this is legacy
code used in thousands of classes, so is difficult to change, but again that
should not detract from the question
but thanks for the tip Howard,

T5.1 default locale for app.properties: bug or feature?
Hi, My application uses *"ru"* as default locale. It works ok for component message properties. I don't have *"acomponent.properties"* files, only *"acomponent_ru.properties" *and it work right. However when I create global message catalogue - *"app_ru.properties"*(without "app.properties"), it is not used by Tapestry. When I rename it to *"app.properties"* - it is used. *Is it by design or bug?* Regards, Sergey.
Re: embedded components
I already guessed that I'd get "static structure, dynamic behaviour" as
an answer but declaring the component inside the page class *IS* static.
I don't see the need to also have it in the template.

or you could create a base page that contains all Blocks and components

Why do embedded components declared with @Component _have_ to have a
corresponding element in the template? If I just want to use them as a
return value from some delegating method, why do I still have to declare
them in the template, bloating it with unused stuff?

update a zone from within a component
Hi List, How can I update a zone on a page from within a component placed on that page?

Re: Testify injection only works once per test
Hi Paul,
Yes there are three groups involved in the suite.
How ever no other test from other groups are available.
It seems that when I remove the reference to groups in my testng.xml it
works fine.
For now a workable solution it looks like a bug though not sure wether
testng or testify.
thanks anyway.

Re: Testify injection only works once per test
Hi Paul,
I have this test method
@Inject
private TestPageResultRetriever retriever;
@Inject
private RBUTypeRepository repository;
@Override
protected void doSetUp() throws Exception
{
}
@Test(groups = "rbudisplay")
public void test_rbuselection_fulltype() throws Exception
{
Document doc =
tester.renderPage("multiselect/rbuselectiontestpage");
List selectelements =
TapestryXPath.xpath("//select").selectElements(doc);
assertEquals(selectelements.size(), 2);
Iterable options = getSelectElementOptions(doc,
"//table/tr[1]//select[1]");
assertEquals(Iterables.size(options), 3);
selectOptionElement(options, 1);
Element textfield =
TapestryXPath.xpath("//table/tr[1]//input[1]").selectSingleElement(doc);
textfield.forceAttributes("value", "1");
Iterable options2 = getSelectElementOptions(doc,
"//table/tr[2]//select[1]");
selectOptionElement(options2, 1);
Element hidden =
TapestryXPath.xpath("//table/tr[2]//input[1]").selectSingleElement(doc);
assertNotNull(hidden);
Element form = doc.getElementById("rbuselection");
tester.submitForm(form, new HashMap());
RBUSelection selection = getSubmittedRBUSelection(1L);
assertNotNull(selection);
RBU rbu = selection.getSelection();
assertEquals(rbu.getId(), Long.valueOf(2L));
}
private RBUSelection getSubmittedRBUSelection(Long id)
{
RBUType type = repository.findById(id, false);
RBUSelection entry = new RBUSelection(type);
RBUSelection selection = retriever.getEntry(entry);
return selection;
}
When I run the test within a suite the test fails in the
getSubmittedRBUSelection method on the first statement which as you can see
is being called at the forth statement before the end of the testmethod.
the repository is already been used in the page aswell otherwise I would
have recieved an exception from there.
When i run the test alone with its class it works

[T5] JPF-Plugins (or any other plugin-framework) to add page content?
Hello everyone, I need to write an application where multiple page contents should be added in later via plugins - for example different ways to output things, other payment modi, or statistics. Currently I am reading into http://jpf.sourceforge.net/index.html, but it is not necessairly a JPF problem: How can I add Tapestry pages and classes later in "per hand"? Or can you think of any other way plugin support could be made possible? Can anyone can make sense out of what I am trying to do? I would love some ideas, hints and solutions, because I'm stuck.

Hi,
Before I open a jira for this I have devised an coded example to
illustrate it, and hopefully get some comments:
//Example: The shell of an eagerloaded service
public class ImageService {
/** Cache to hold thumbnail images */
private static ConcurrentHashMap
imageCache_ = new ConcurrentHashMap();
public void preloadImageCache() {
DbConnection connection = null;
try {
//Sometimes this turns into a Null Pointer
Exception as another eagerloaded service sets up the connection pool etc.
//this service should start up after that one, but
this is not always the case in practice??
connection =
DatabaseConnection.getReadConnection();
//database query
} catch (Exception e) {
//handle exception
}
}
public static ImageService build() {
return new ImageService();
}
public ImageService() {
preloadImageCache();
}
}
//Workaround: adding a dependency on the other eagerloaded service solves
it, but this is not a practical solution if there are many of these
services

private static ConcurrentHashMap
imageCache_ = new ConcurrentHashMap();
public void preloadImageCache() {

this is not an issue, perhaps this is a regression from the fix to

As I understand the Tapestry IOC, it shouldn't make any difference. Generally, service objects are actually proxy objects; with non-singleton scopes the proxy object is responsible for forwarding calls to the correct instance of the service. For example, to quote the documentation, "With perthread, the service proxy will delegate to a local service instance that is associated with the current thread. Two different threads, invoking methods on the same proxy, will ultimately be invoking methods on two different service instances, each reserved to their own thread." See "Defining Service Scope" on: http://tapestry.apache.org/tapestry5.1/tapestry-ioc/service.html This ingenious feature is what allows Tapestry IOC to inject a per-thread service into a singleton service and have that work correctly. If you are setting up state that you want to be fresh for each test, then you should consider using Testify's pertest scope: http://tapestry.formos.com/nightly/tapestry-testify/#Per-test_scope Paul --- This e-mail may contain confidential and/or privileged information.

because i couldn't control the ordering of eager load services
i stated that no developer may define an eager load service
himself. instead i created an eager load service (StartupInitializer)
that accepts an orderedconfiguration of initializers every
developer must contribute to.

Re: Tapestry 5 IoC Eagerloading and ordering of services
Hi,
Before I open a jira for this I have devised an coded example to
illustrate it, and hopefully get some comments:
//Example: The shell of an eagerloaded service
public class ImageService {
/** Cache to hold thumbnail images */
private static ConcurrentHashMap
imageCache_ = new ConcurrentHashMap();
public void preloadImageCache() {
DbConnection connection = null;
try {
//Sometimes this turns into a Null Pointer
Exception as another eagerloaded service sets up the connection pool etc.
//this service should start up after that one, but
this is not always the case in practice??
connection =
DatabaseConnection.getReadConnection();
//database query
} catch (Exception e) {
//handle exception
}
}
public static ImageService build() {
return new ImageService();
}
public ImageService() {
preloadImageCache();
}
}
//Workaround: adding a dependency on the other eagerloaded service solves
it, but this is not a practical solution if there are many of these
services
public class ImageService {
/** Cache to hold thumbnail images */
private static ConcurrentHashMap
imageCache_ = new ConcurrentHashMap();
public void preloadImageCache() {
DbConnection connection = null;
try {
connection =
DatabaseConnection.getReadConnection();
//database query
} catch (Exception e) {
//handle exception
}
}
public static ImageService build(SiteInitialise
siteInitialise) {
return new ImageService(siteInitialise);
}
public ImageService(SiteInitialise siteInitialise) {
if(siteInitialise.isConnectionOk())
preloadImageCache();
}
}
If there is a way to ensure the ordering of eagerloaded services, then
this is not an issue, perhaps this is a regression from the fix to
http://issues.apache.org/jira/browse/TAPESTRY-2267 ? otherwise I am
surprised that others have not come across this, perhaps I have missed
something?
Cheers,
Peter

Re: Testify injection only works once per test
I think that @BeforeMethod is a better one to key off-of. If singleton-scoped objects are the only ones being injected, then @BeforeClass makes sense, but if you're testing per-request or per- session objects, then it's best to use @BeforeMethod, since you may be setting state on these which needs to be fresh for each test. cheers, Christian.

Hi everyone,
Is it possible to control the ordering of eagerloaded IoC services,
especially if the services exist is separate but dependent IoC modules.
I found an issue http://issues.apache.org/jira/browse/TAPESTRY-2267 that
states these service proxies are claimed and loaded collectively, however
no mention is made of how to ensure the correct ordering of these claimed
services?
Any help with this would be greatly appreciated.

Sorry, I was wrong. In my case the problem was that "redirectTo" url was created before session. And thus before putting jsessionid in url. So the login was working fine - it was appending "jsessionid" to the url and then my code was redirecting to the old "redirectTo" url without "jsessionid".
