Problem with tapestry grid inside form
Hi, I am using tapestry 5.0.16. I have a grid,2 submit buttons embedded inside a form. One of the column in the grid displays checkboxes. After coming to the page (for eg:5 rows in the grid),if I manually delete a record from the database and click any of the submit buttons it is showing exception index 4,size 4. If I click after refreshing the page,this problem does not occur. But I don't want to refresh the page.How can I handle this scenario? I tried using volatile=true.Then this is okay.But while taking action on the form, the checkbox states that I have changed is not taken for updating the database. Please help ...if anybody have idea on this. Please explain in detail if there is some solution for this..

Re: Tapestry behaving strangely in production environment
We got the solution for the issue. There were 2 hibernate.cfg.xml files that need to be modified. Earlier we have modified only one, thinking that the second one (inside the jar that contains the POJOs) will be ignored.But tapestry tries to contact the second file at times. Now we have only one hibernate.cfg.xml file -- View this message in context: http://www.nabble.com/Tapestry-behaving-strangely-in-production-environment-tp25954098p26038183.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
T4: bug in expression cache?
Hi, I have copied and changed the Dialog component in my project (Tapestry 4.1.5) in order to create a HelpBalloon popup. This gives me the following files that I've added to my project: HelpBalloonDialog.java HelpBalloonDialog.jwc HelpBalloonDialog.script I kept the condition checking the same as in Dialog.script, i.e.: script input-symbol key=component required=yes / initialization if expression=component.hidden do_stuff(); /if if-not expression=component.hidden do_different_stuff(); /if-not /initialization /script This is essentially the same construction as Dialog.script uses, and most importantly the expression string component.hidden is exactly the same. Requesting a page however where Dialog is used gives me a cast exception when it tries to use the cached compiled expression that it finds. Changing the name component to something else makes the problem go away. Now, looking at the code I'm seeing the following: The ExpressionCache uses the symbol map in ScriptSessionImpl as its key, so therefore the cache should be local to a script and I should be allowed to use the same expression in different scripts. Is this the intended behaviour, am I missing something or am I looking at a bug? Kind regards, Marc van Kempen.
T5: how to put Testify into real use?
Hi,
I have tested Testify with a simple sample and manage to make it work:
public class MyPageTest extends TapestryTest{
private static final TapestryTester SHARED_TESTER = new
TapestryTester(org.apache.tapestry5.tutorial,
TestModule.class);
public MyPageTest() {super(SHARED_TESTER);}
@Override
protected void setUpForAllTestMethods() throws Exception {
MockitoAnnotations.initMocks(this);
}
}
public class MyTest extends MyPageTest{
@Test
public void testElementIsOnPage() {
Document page = tester.renderPage(index);
Assert.assertEquals(page.getElementById(123).getChildMarkup(), this
is 123);
}
}
public class TestModule {
public static void bind(ServiceBinder binder) {}
}
above code works, I added following to my AppModule:
public RequestFilter buildUtf8Filter(
@InjectService(RequestGlobals) final RequestGlobals
requestGlobals) {
return new RequestFilter() {
public boolean service(Request request, Response response,
RequestHandler handler)
throws IOException {
requestGlobals.getHTTPServletRequest().setCharacterEncoding(UTF-8);
return handler.service(request, response);
}
};
}
And I get this exception all the time, how to take care of this situation in
Testify? thanks.

Tapestry is pretty verbose when it starts up, telling you what modules it has loaded and what pages/components/mixins it knows about. I wish some other frameworks would do something similar.

Re: T5: Weird problem with browser cache and component event redirect
Hi Toby, thank you very much for your hints. Since we have a tapestry-only application, i added a request filter that sends the cache control headers (expires, pragma, cacha-control, last-change etc.). I used your settings with no success so far. But I finally found a solution: I am appending a random string to all urls with the tapestry url-rewriting machanism, so browsers can't cache them. This is an ugly workaround since all urls look now cryptic, but it works. On our test-environment we have encountered similar problems with other websites, so maybe this problem is not tapestry related at all but occurs very often since the request-redirect-request mechanism is used on every page. Maybe this is a browser-bug (strange thing is we have it in firefox and customers report problems with IE 7). If anybody has problems like this: Please report here. Thanks Felix Toby Hobson schrieb: I've had similar problems (caching in general). I was running a mixed T5/Spring MVC app so in the end I wrote a filter which set the various http headers and I then mapped certain requests to that filter. In the end I found that I needed to set quite a few cache related headers to get things working across all browsers: filter filter-nameNoCacheFilter/filter-name filter-classcom.thc.util.servlet.ResponseHeaderFilter/filter-class init-param param-namecache-control/param-name param-valueprivate,no-cache,no-store,must-revalidate,max-age=-1/param-value /init-param init-param param-namepragma/param-name param-valueno-cache,no-store/param-value /init-param init-param param-nameexpires/param-name param-value-1/param-value /init-param /filter As you see I needed to set the cache-control, pragma and expires headers to get it to play nicely You might want to try something along those lines, of course if you have a pure T5 app you could you a Tapestry filter instead of a standard servlet filter as I did 2009/10/23 Felix Gonschorek fe...@ggmedia.net Hi all, we're experiencing a weird problem here with a live system (big b2b enterprise shop frontend): Some users report that nothing happens when they click on links. We narrowed things down and found out that only component event links are affacted that do not redirect to another page, for example: Page is: /productlist. The page contains a product listing with a pager - users can navigate with the pager (switch pages, sort products) When the user clicks on an pager event link to go for example to the second page, the link looks like this: /productlist.pager:gotopage/2. The event handler sets the page number session variable to the value 2 and returns null - the same page (/productlist) should be rendered again - but this time page two of the paged product list should be rendered. On most browsers and clients this works, but as mentioned: Some browsers do not follow the header Location - i can see it in the logfiles on the server. The PageRendering request (header: Location) is not executed and the client loads the page from the browser cache - and page 1 of the paged products is displayed. So the users experience that nothing happens. We heard from users using internet explorer 7 on the live system (tomcat 6 behind apache with mod_jk) experiencing this problem and we could reproduce this with one system on our test environment (jetty 6, firefox 3.0.14) - the browser does not follow the Location header. If we deactivate the browser cache completely on firefox the problem does not occur. Only thing special we have is a X-Ua-Compatible header to force internet explorer 8 to be IE7 compatible. In the meanwhile we added the last-modified,expires,pragma and cache-control header to modify the browser cache behaviour, but so far with no success. This are the server response headers for the component event request: HTTP/1.x 302 Found Location: http://localhost:8080/drw/en/productlist/$N Content-Length: 0 Server: Jetty(6.1.16) This are the server response headers for the page render request: HTTP/1.x 200 OK Last-Modified: Fri, 23 Oct 2009 12:51:42 GMT Expires: Mon, 26 Jul 1997 05:00:00 GMT Content-Type: text/html; charset=utf-8 X-Ua-Compatible: IE=EmulateIE7 Pragma: no-cache Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Transfer-Encoding: chunked Server: Jetty(6.1.16) Has anybody experienced similar problems? Does anybody have a hint how we could force all browsers to do the page render request after the component event request, even if we do not change the page? As the problem occured on jetty and tomcat, firefox and internetexplorer we assume that some headers are incorrect, but we don't know which. Any help is much appreciated!

When I include the containing object (Car in my example) in a

Is there any easy
way to coerce it to display as if it's fields were part of the
original, apart from writing a bean model?
You can add methods like getRegistrationDate() { return
registration.getDate(); } to your Car class.
Another option is to add the Registration properties to the Car BeanModel:
@Inject
private BeanModelSource beanModelSource;
@Inject
private PropertyConduitSource propertyConduitSource;
BeanModel model = beanModelSource.create(car);
model.add(registrationDate, propertyConduitSource.create(Car.class,
registration.date);
containing objects, and I was wondering if there's anyway to annotate
the Registration object to tell Tapestry automatically inline this
object's fields into the owning object's generated bean model or
something like that.
You can file a JIRA for that.

T5.1 - Select component with validation error
Hello everyone, Is there any reason why the t-error CSS class is not assigned to a Select component when it is in error? Moreover, a Select component in error does not get the keyboard focus when the form is rendered. How can I fix this so that Select components get the same treatment as, say, TextField with regard to validation errors? Thanks, Benny Law
