Problem setting request parameters using PageRenderLinkSource
Hi,
I have a select component onchange of whose value I'm returning a PageLink
with request parameters. The id for the select component is pcat. Please
find the method being called on change of the value.
public Object onValueChangedFromPcat(ItemCategory pcat) {
this.pcat = pcat;
this.cat = null;
this.refreshModels();
this.refreshCatModels();
this.refreshGallarymodel();
// Generating the Link
Link fwd = pageRenderLS.createPageRenderLink(ItemBrowse.class);
// Adding the request parameters
fwd.addParameterValue(pcat, this.pcat);
fwd.addParameterValue(cat, this.cat);
fwd.addParameterValue(coll, this.coll);
// Debug - clean up
log.debug(URL VALUE + fwd.toAbsoluteURI());
return fwd;
}
On doing so the URL on the browser comes out as:
http://localhost:8080/km/store/itembrowse%3Fcat=$Ncoll=$Npcat=20120311143401335000
On the other hand the debug message shows it as:
http://localhost:8080/km/store/itembrowse?cat=$Ncoll=$Npcat=20120311143401335000
If you see closely instead of '?' the hex value of '%3F' is populated which
translates to '??' and I get an exception as:
java.lang.IllegalArgumentException
Input string 'itembrowse?cat=$Ncoll=$Npcat=20120311143401335000' is not
valid; the character '?' at position 11 is not valid.
I haven't faced this issue when the url is generated using the t:pagelink
tag but only when using PareRenderLinkSource to generate the URL.
Is this a Tapestry issue? Please do advice as to what could have caused this
to happen and if it could be resolved.
Thanks and Regards,
Srijith

Re: Problem setting request parameters using PageRenderLinkSource
out of curiosity, do you still get the exception when you put teh debug URL
into your browser address bar?

Grid Pager events leave out request parameters
Just thought I'd better check this before filing an issue in JIRA... When I click on a GridPager link, it seems the pages's activation context is sent through but not the request parameters. It's a real problem since I like to put search/filter criteria into the request parameters, so I lose them every time. Can anyone confirm I've got this right?

Re: Grid Pager events leave out request parameters
Hmmm, it seems EventLink has the same problem - it sends through the page's activation context but not its request parameters. This is in T5.1. Is T5.2 the same?

Re: T5 template selection based on the current request (e.g. request parameters)
Yep, you're right. But there are several posts that state that there is a one-to-one relationship of page class and template (with support for i18n'ed templates). Having such a simple solution I wonder where these statements come from and if they are completely wrong. And the question is, if the mentioned solution works correctly without side effects, having the full template lifecycle supported (however this works in detail). So do you say, that the shown solution is working correctly? Thanx cheers, Martin On Thu, 2008-02-07 at 01:17 +0100, Renat Zubairov wrote: Hello Martin, What isn't clear, is what is the question?

Re: T5 template selection based on the current request (e.g. request parameters)
I'm not 100% clear either. A page class has one and only one page template, albeit localizeable. It seems like you'll need to do at least 2 things: 1. Use a Layout component specific to the user/page. For this you will have your page template wrap itself in a layout component, the exact type of which must be determined at runtime. If I'm not mistaken there is a way to do this using a delegate or placeholder, but you'll need to look at the core docs to be sure. 2. Embed blocks your page component which render the specifics. You can render these blocks conditionally using t:if. Granted your page will look a bit cobbled, but that is what requirements like this dictate. I've not heard of any method more elegant than this unfortunately - you can see the same thing in RoR (widgets, etc). Hope this helps - sorry I couldn't be more specific about the dynamic layout. chris Martin Grotzke wrote: Yep, you're right.

Re: Request Parameters
It's not clear to me what exactly is your goal if it is, as I think,
dinamically generate a tapestry url inside a javascript you should
then look at one of the IEngineService (depending
on the type of service your link will be bound to):
http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/engine/IEngineService.html
in particular the getLink method.
In fact I think there is a lack of documentation in tapestry about how
to properly generate url.
The most common case (action/listener links for forms or not) you
should look at DirectService
http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/engine/DirectService.html
and the Object passed to the getLink method (even though not
documented) should be of type
DirectServiceParameter
(http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/engine/DirectServiceParameter.html)
You can see the types of parameters that can be passed reading
DirectLink component documentation
(http://tapestry.apache.org/tapestry4.1/components/link/directlink.html)
Hope this can be of some help.

Hi Vitaly. Have a look at FAQ number 2.7: I need to calculate a URL to jump to a particular page. How do I do this? http://tapestry.apache.org/tapestry4/faq.html This shows you how to generate URLs for a page that implements IExternalPage. Cheers, Nick.

Good day! I have tapestry application. I want users enter in browser http://mycompany.com/mytapestryapp?param1=test, and my page class receive value test in it's property param1.

Typically, you don't have users manually type request parameters into their browser.

RE: How can I access request parameters in my page class?
Poka, Vitaly ; ) If you absolutely need access to the servlet API, and can't find a way to do what you want that is more Tapestry-ish, you can inject certain service-objects into your page. Here are the relevant HiveMind service points: http://tapestry.apache.org/tapestry4/tapestry-annotations/hivedocs/modul e/tapestry.globals.html So, for example, in your case, you need access to the HttpServletRequest functionality. Two options: you could inject the HttpServletRequest directly into your page: @InjectObject(service:tapestry.globals.HttpServletRequest) public abstract HttpServletRequest getRequest(); Or you could use the Tapestry wrapper/abstraction class: @InjectObject(service:tapestry.globals.WebRequest) public abstract WebRequest getRequest(); In both cases, you'll be able to access the request parameters as you're used to (e.g. ... String param1 = getRequest().getParameter(param1); ...) This is assuming, though, that your users know enough about how Tapestry URLs are structured so that they're getting to the page you intend, which is tricky, error-prone, a security-risk, and technically locks your application into a specific version of Tapestry, since a future of Tapestry could very well structure those URLs very differently.
