T5:Page navigation
Hi,
I have a login page, when user logins, it navigates to next page. How can I
hide the login page when I click the back button from IE. I am using
onActive() in Login page likes:
String onActivate()
{
if (!_user.isLogin()== true) {
return null;
}else{
return "Start";
}
}
But it still shows the login page.
Thanks.

RE: EventListener questions
If you are using a DirectLink or a Submit button you do not need to use
the @EventListener annotation. You can specify using updateComponents
which elements to refresh. See
http://tapestry.apache.org/tapestry4.1/components/link/directlink.html
and http://tapestry.apache.org/tapestry4.1/components/form/submit.html
for available parameters.
Example:
Link
The idOfAreaToUpdate is the id of a component () and not just the id of a div.
If you use @EventListener, see
http://tapestry.apache.org/tapestry4.1/ajax/eventlistener.html for
examples and also check out Kent Tong's book:
http://www.agileskills2.org/EWDT/. Chapter 11 has edit and delete
examples.
If you want to use javascript, try using scripts. You can include a js
file and do some dynamic scripting.
http://tapestry.apache.org/tapestry4.1/components/general/script.html

Hi I was wondering what the correct way would be to create an
EventListener that returns a confirm when a button is clicked.
I have the following that doesn't work:
@EventListener(elements="deleteButton", events="onclick")
public String testThis(){
return "return confirm('"+
appMess.getString("delete.case") +"')";
}
@Component(id="deleteButton", type="DirectLink", bindings={
"parameters=ognl:currCase",
"renderer=bean:buttonRenderer",
"listener=listener:deleteCaseListener",
})
public abstract DirectLink getDeleteButton();
What is the correct way to go about doing something like this?

T4.1.1 stateless contrib:table
I am needing to provide sortable contrib:Tables in my application, but I need them to survive a session timeout. I normally buckle and make the TableView source persist in the session, but that is never a very nice solution. I am providing my own IBasicTableModel, so I'm reloading the table data on each request. I thought I could use the new TableView persist parameter to persist the table state to the client, as in: Rendering a table, killing the application, restarting the app, and then clicking on a sortable column header results in a StaleSessionException. I have tried implementing my own ITableSessionStateManager, but the default manager along with client persistence I thought should work. I would really appreciate some input if anyone has been able to implement a truly stateless table.

Re: Tap 4.1.1 problem: async direct link returns empty ajax response
No things should still work the same with 4.1.1. .(but upgrading might
be a good idea either way)
The error you got means that you don't have a component defined in
your page with an id of "div1". Your example before on how you were
defining your div blocks was incorrect and I provided an example of
how to do it...ie :
It'll work if you define your block that way.

Re: Tap 4.1.1 problem: async direct link returns empty ajax response
Jesse,
Thanks for your response. This feels like the problem, that the IDs on
the tags are not being matched. However due to my lack of
knowledge about Tapestry's internals, I haven't been able to implement
your suggestion.
What I can't figure out is how to get the clientId out of the OGNL
expression you used (page.components.div1.clientId). I had a look at
what is in the Map that page.components returns, and I don't see
anything that looks like my components' clientIds in either the
component.getClientId() or in the set of keys of the components Map.
How do I get the clientId from a component named "div1", given that I'm
in a For loop as well? I'm confused about what the updateComponents
parameter in the DirectLink component should take instead of the IDs on
the s since I can't seem to retrieve the clientIds.
Here is what I am doing now, using components with IDs to try to follow
your example:
In the .jwc file I have two components for s that look like this:
These are used to display the s in the .html file, which will be
updated by the asynchronous DirectLink.
Then in my DirectLink component:
updateComponents="ognl:{'ratingImage' +
hunch.id,'ratingStars' + hunch.id}">...
If you or anyone else can help direct me to the right way to get the
clientIds for components for use within the updateComponents parameter,
that would be greatly appreciated. I have looked at the source code and
APIs but so far that hasn't cleared it up.
Cheers,

I'm guessing that the clientId of the div's you are trying to update
doesn't match on these responses.
One thing you could do as a test is if you currently do something like:
wrote:
I have just run into a problem that I think is probably a bug, but may
be something that I am doing wrong. It's definitely a showstopper in my
app, though.
I have a component that allows users to rate something via the normal
kind of "stars" rating. After a user clicks a star the overall rating
of the object is calculated and displayed as a graphic. I use a
component that employs an asynchronous DirectLink to do this, with each
star having a different value on submit, and it works quite nicely. I
have this custom component on two different pages and I can submit
ratings on both.
However, I just added pagination, and as soon as you move off of the
home page via the "next" pagination link, the DirectLink for ratings no
longer returns anything. The pagination works using the standard kind of
"start from" parameter, which calls a listener that simply does
setStartFrom(int startFrom) and then lets the pageBeginRender() method
calculate the objects to display.
I do know the reason that the ratings no longer show the updated
graphic--the AjaxResponse just returns empty tags, with no errors
reported at all (had a look at this with firebug):
The actual link is firing just fine, and all of the server side
processing happens as my logs show. It's just that the ajax response is
empty when it should include new HTML for the s to be updated. It
seems like there is some kind of setup that happens when you go directly
to Home.html and click the rating link, but not when I've gone to the
home page via a DirectLink. I cannot see what would be different, since
my pageBeginRender() method is called, and everything else happens just
like it should in the component and in the page.
If anyone has run into this before or has an idea regarding what this
might cause an async DirectLink to return nothing in some cases, please
let me know. The pagination is a major part of my app, and users need
to be able to submit ratings no matter which page they are on, so I am
kind of dead in the water until I get this fixed. Next step is to spend
quality time with the source code, but if anyone has a better idea
before I take that time...
Cheers,
Matt

Re: T5: Best page templating strategy
I got a good start on this, but still missing something fundamental.
In Page.java, I have the Sidebar component.
In Page.html, I pass the component in a parameter
In Layout.java I have a sidebar block
@Parameter(required=true)
private Block _sidebar;
What I can't figure out is how to get the block to render.
Thanks for all of your suggestions so far!

Is OGNL 2.7 compatible with JDK 1.4 ?
I'm asking because i'm getting this error running it: Caused by: java.lang.RuntimeException: java.lang.RuntimeException: java.lang.NoSuchMethodError: java.lang.Integer.valueOf(I)Ljava/lang/Integer; at ognl.ASTProperty.toSetSourceString(ASTProperty.java:548) at org.apache.tapestry.services.impl.HiveMindExpressionCompiler.generateSetter( HiveMindExpressionCompiler.java:386) at org.apache.tapestry.services.impl.HiveMindExpressionCompiler.compileExpression (HiveMindExpressionCompiler.java:162) at ognl.OgnlRuntime.compileExpression(OgnlRuntime.java:388) at ognl.Ognl.compileExpression(Ognl.java:123) at org.apache.tapestry.services.impl.ExpressionCacheImpl.parse( ExpressionCacheImpl.java:129) ... 65 more It seems that it's looking for an implementation of Integer.valueOf(Integer).

Re: session persistance?
Yes, from what I understand persist is just to keep value between
request. so every-time you request the page the object is in this
case recreated.
If you want to keep this object across a session you need ASO (see T5
doc on persistence).
You can also (but will not be kept a session level) perform a test in
your class to instantiate only once the object and keep it for the
page or request only.

Hi there --
does anyone have some thoughts on why:
@Persist
@InitialValue("new java.util.HashSet()")
public abstract Set getFollowUpMessages();
public abstract void setFollowUpMessages(Set set);
keeps on resetting the set to a new HashSet between http requests?
It looks like according to the @Persist documentation this is the
correct
way to set an initial value if there is no value already in the
session. But
it seems not to be the case...

My question is, how do you best handle multi-part layouts?
For instance, a Layout can be composed of a Body and a Sidebar. The
Sidebar can be a component.
My current approach is to have a
Page.java:
public Page {
@Component
private Layout _layout;
@Component
private Sidebar _sidebar;
}
Page.html:
fee fi fo fum
This feels suboptimal, as I'm encoding the location of the sidebar
into each and every page (namely always coming after the main div).
I'd like to have the Sidebar component in the Layout component, but
feed this component from the Page to the Layout (as the Sidebar
component could be different on every page). I.e., sidebar="sidebar">, but that is a parameter, not a component, so
afaik won't work like I expect it to (it didn't in testing, but

Any way of accomplishing this? Any better solutions to this

Downloading an offline copy of the 4.1 documentation
Hi, Can anyone tell me how to create an off-line version of the tapestry 4.1 website? I tried to download it by getting the tapestry-site project from svn, and build it with maven - something I've not used before, by following instructions on the tapestry site, but, 1. the instructions didn't work, and 2. after much fiddling and guessing, I managed to get it to build something but it seemed to just be the shell for the site - no documentation etc was working - all links broken and no files on my PC, so I guess I downloaded the wrong thing. I'm having to do this over a dial up connection, so if anyone can provide a solution I'd be very pleased - the 4.0 docs are I discovered not as up-to-date as I need as a beginner.

Re: Visit Object deprecated
Thanks everyone for the confirmation about the visit object - I've been using the ASO idea, but sticking to a "visit" object at present - worried about drifting too far down aisles unknown (to me a beginner) and getting stuck! - Original Message From: Howard Lewis Ship <[EMAIL PROTECTED]> To: Tapestry users Sent: Monday, 9 April, 2007 4:22:25 PM Subject: Re: Visit Object deprecated In Tapestry 4, they are more generic, called "ASOs".
