Unsubmitted sub-forms loosing values when using within
Hi,
When is used within , subforms that are not
submitted loose value changes (they load values from the model even if
preserveSubmittedValues="true").
In the following UI Mark up, I make changes to the first name and first
score and click submit. Changes made to score are retained (as it is part of
the submitted sub-form) but changes made to name are not retained.
The controller is:
class ContentController
{
private List students; public List getStudents() { if
(null == students) { students = new ArrayList(10); for ( int i = 0;
i < 10 ; i++ ) { String studentName = "Name" + i; Student student = new
Student(); student.setName(studentName); student.setScore(i);
students.add(student); } } return students; } public String add() { return
null; }
}
Student.java:
public class Student { private String name; private int score; public String
getName() { return name; } public void setName( final String name ) {
this.name = name; } public int getScore() { return score; } public void
setScore( final int score ) { this.score = score; } }
Would appreciate any pointers on what could be going wrong.
TIA,
Babu

Re: [Trinidad] TRINIDAD-779 PPR not triggered when deleting last row from table

I think the JIRA issue has a reasonably standalone testcase so I can certainly
turn that into a maven-based testcase over the next day or so. It will also
help me validate whether or not I'm seeing exactly the same problem.
Do you know if there's a maven archetype which includes trinidad and facelets?

Re: [Trinidad-Sandbox] trs:tableFormLayout renderer problem
Hi Glauco Sorry for the late response, but right now I'm busy contributing to myfaces core 2.0. I'll try to be as concrete and simple as possible to explain this issue. To understand how this component works you have first to check a working example of it. Trinidad 1.2.8 is the nearest version that works with this component. You can checkout the source code from here: http://svn.apache.org/repos/asf/myfaces/trinidad/tags/trinidad-1.2.8/ Then change all trinidad-sandbox pom.xml versions from 1.2.8-SNAPSHOT to 1.2.8 (sandbox-api, sandbox-build, sandbox-impl, sandbox-demo and trinidad-sandbox pom.xml), to make it compile. Type on trinidad-sandbox directory: mvn install then: cd sandbox-demo mvn clean -PjettyConfig jetty:run Then open your browser and type this address: http://localhost:8080/sandbox-demo/faces/components/tableFormLayout.jspx If everything is right (I tried all instructions) you should see the component working. The important part here is have a reference of html markup. Now the problem. LabelAndMessageRenderer is the base renderer of all "labeled" trinidad components. It works with tr:panelFormLayout to render correctly components inside a html table rendered by this component. In few words, when a labeled trinidad component is rendered alone it does something like this (it is more complex than the example but the example shows the idea): "label""component" inside a tr:panelFormLayout or tr:tableFormLayout, LabelAndMessageRenderer do something like this: .some table stuff by the container.."label""component"...some table stuff by the container >From this point of view the problem is simple, LabelAndMessageRenderer should recognize the container in the same way as recognize tr:panelFormLayout and render "almost" the same code as tr:panelFormLayout. I hope this description helps to solve the problem regards Leonardo Uribe On Wed, Apr 15, 2009 at 9:44 PM, Glauco P.

Re: how to add post-data to a redirect from an action
Hallo Walter,
thanks for Your reply.
I have tried to understand what ist httpclient, but I am not shure if
I am right.
What I guess is that httpclient can manage the client-communication to
a web server.
That means I can make programs that interact with a webserver. (like
calling an url with some data and process the response.)
What I want to do is: inside my WebApp - when the User pressed a
button - I want to redirect the User to another WebApp on another
server provided with some post-data. The answer to this request to the
second WebApp should never arrive at my WebApp but should be
interpreted by the User's browser.
Do You think, httpclient can help me doing this?
Thanks,
Georg

Re: [Trinidad] TRINIDAD-779 PPR not triggered when deleting last row from table
Just tried it and no luck :-(
Note that the delete() method in my case is in context of a popped up dialog so
the line:
UIXTable table =
(UIXTable)FacesContext.getCurrentInstance().getViewRoot().findComponent("tableId");
... returned null so I got to the UIXTable object through an associated backing
bean. Not sure whether any of this matters though...
Assuming we can't think of a workaround, what are the chances of anyone in the
core dev team being able to work on this? Or do I need to put some time aside
to debug this myself?
thanks
Paul.

one more guess.
in the delete, did you try something like this ?
public String delete()
{
...
List myList = // get the thing;
myList.remove(...);
// store the "change"
UIXTable table = (UIXTable)
FacesContext.getCurrentInstance().getViewRoot().findComponent("tableId");
table.setValue(myList);
RequestContext rc= RequestContext.getCurrentInstance();
rc.addPartialTarget(table);

Re: [Trinidad] TRINIDAD-779 PPR not triggered when deleting last row from table
Matthias - thanks for the response. We tried addPartialTarget on the table component itself - i.e. on the action method which deletes the object we tried calling addPartialTarget() on the table. Unfortunately, that didn't help. We also tried adding a return listener on the commandButton which launched the dialog (which contains a commandButton that subsequently deletes the object) and then calling addPartialTarget from the return listener. However, it looks like the same issue causes the return listener not to be called - i.e. if the action results in its commandButton disappearing then the return listener is not triggered. I've just tried addPartialTarget on the document and the UIViewRoot and no joy I'm afraid. Any other pointers (or a fix!) would be really appreciated... thanks Paul.

tree2 menu
I have created a menu with the help of the tree2 component. But I have also on the same pages the buttons for next page and previous page. I want to change the selected item from the tree2 when the page is changed by clicking on the next button.

[Trinidad] TRINIDAD-779 PPR not triggered when deleting last row from table
Hi all, We're about to go production on our web site within the next month, but we're hitting a number of issues caused by the above bug. We see it not only on deleting rows from a table but also when updating certain tables - basically, PPR does not occur after any action which causes the source command link/button to disappear. This is a real showstopper for us. Is there any chance any of the Trinidad gurus could look into this? thanks Paul.
[Trinidad 1.0.10] error in TrRegExpValidator
Hi, I was running in an issue in Trinidad. I have used the following tag and I was wondering why nothing has matched with my pattern. So I was going to debug the JavaScript implementation of TrRegExpValidator.prototype.validate function and I have seen that the match function was invoked with a wrong parameter (instead of exactPattern, this.exactPattern was used). This would never match because TrRegExpValidator has no member variable. Should I file a Jira issue for this? Best Regards, Sven Rottstock
Re: how to add post-data to a redirect from an action

Re: how to add post-data to a redirect from an action
Hallo Simon,
Yes You have understood right: I want the user's browser to call
another server and dont want to continue processing my application
afterwards.
I also have thought about the JavaScript solution.
But using a js solution generally I will write the xml-data into the
user's html. I did'nt like to do that, because this (xml-)data grants
You access to the other application. For this reason I wanted to hide
the xml-data. But using get-Parameters the xml-data is visible the
same.
Maybe should think about a ajax- functionality like this:
I use a commandbutton that supports ajax-request and a hidden form
that makes a post-request.
When the user clickes the commandbutton i can fill the data of the
form via ajax and then in an after-ajax-event click the submit-button
of the form via JavaScript. Do You think this will work?
I hoped, there would be an more easy way
Thank You for Your help.
Regards
Georg

One option could be doing some sort of logic (e.g. extracting req param) in the constructor of a backing bean. Another option is using Orchestra's view controller Or, using this tool: http://jsf-comp.sourceforge.net/components/on-load/index.html > > Thanks, > Anton. > > > -- Matthias Wessendorf blog: http://matthiaswessendorf.wordpress.com/ sessions: http://www.slideshare.net/mwessendorf twitter: http://twitter.com/mwessendorf
[JSF] How to execute action directly from link (like struts action)
Hi all, I need advice/suggest for such situation: is there any way to execute an action in bean/(in listener) when user requests certain jsf page? - for example: /customer/edit.jsf?id=172387 Why I need this: I want to make some preprocessing logic before showing the final page. I know there is possibility to make this by @PostCreate execution, but maybe there are other ways, more convenient? Thanks, Anton.

When you say "call another application out", do you mean that you want
the *user's browser* to send a POST command to some other server, and
then display the result returned from that server (without any further
processing)?
HTTP provides no way to do this; the http-redirect facilities only do
GET commands. See the HTTP specification for more details. What your
code above does (extContext.redirect) just generates an http redirect
response, and the user's browser then processes this response and does
the redirect.
HTML provides no way to do this either AFAIK.
JSF just uses HTTP and HTML, so JSF also has no way to do this. I think
you will need to use javascript, ie generate an HTML page that contains
an html with the fields you want, and some javascript that then
does document.getElementById(formId).submit() or something similar.
Or does "call another application out"mean that after a JSF submit, you
want *your server* to send a POST command to some other server, then
process the result before sending back a new page to the user? You can
use the apache commons-httpclient library to do things like this.

how to add post-data to a redirect from an action
hallo,
I have to call another application out from JSF.
To call this application i have to send (xml) data via post to the
start-url of this application.
I found some example on the web:
ExternalContext extContext =
FacesContext.getCurrentInstance().ctx.getExternalContext();
String name = URLEncoder.encode("INTERFACENAME", "utf-8");
String someData = "
";
String value = URLEncoder.encode(someData , "UTF-8");
String viewId = "http://www.server.com/startapp/index.html"+ '?' +
name + "=" + value;
String urlLink = extContext.encodeActionURL(viewId);
extContext.redirect(urlLink);
I tried this code. its calls the new application, but the data is sent via GET:
http://www.server.com/startapp/index.html?INTERFACENAME==%3C%3Fxml+version%3D%271.0%27+encoding.
So the intefacedata is easily be read by the user. Has anyone any idea
how i can make a rediract with POST data?
Thanks
Gio
