JavaScript form submit fails in IE7, works in FF and Safari

Tue, 6 May 2008 13:10:50 MDT

I have a test JSF page that I've created with the following piece of code:

code:

<f:view contentType="text/html">
 General Stuff to be used for debugging
 <h:form id="scratchPadForm">
 <h:inputText value="#{scratch.dummy}" id="dummy"/>
 <h:commandButton type="submit" value="Submit" />
 </h:form>
</f:view>

The 'scratch' bean points to a class I wrote, that implements java.util.Map and uses a HashMap under the covers. I have system.out's in the get and put methods of this backing bean. I'm using RichFaces 1.2 that's bundled with JBoss 4.2.0GA along with facelets, although this page has no facelets code....

Split Pane effect with JSF 1.2, Facelets, Javascript, RichFaces

Tue, 6 May 2008 13:08:50 MDT

This is a follow up on my previous post and describes the root problem I'm trying to solve.

I'm working on a JSF project using JSF 1.2 (the implementation that comes bundled with JBoss 4.2.0 GA), Facelets and JBoss RichFaces/Ajax4JSF.

I basically want to render a page with a nav area and a content area. The content area is to be split in two horizontal areas. The upper horizontal area needs to be a table with scrollable data. When the user clicks a table row, I want to refresh the bottom area with details about the row just clicked. From a UI perspective, it's very similar to yahoo email/outlook... with the top pane showing a list, and the bottom pane showing details.
I've used RichFaces for the data table and p...

Keep-Alive and performance(memory)

Mon, 5 May 2008 18:44:47 MDT

I notice alot of developers using the Session to store their beans. With the Keep-Alive abilities of jsf pages, would this be a better alternative? Which approach would be better for a system with serious usage, 1000-3000 users at any given time?

Component ID .... has already been found in the view with t:dataScroller.

Mon, 5 May 2008 11:46:47 MDT

Hi,

I am attempting to use the paged, sortable table using Tomahawk's t:dataScroller. I am deploying this in Glassfish app server inside a portlet.

When I first view the page, there are no issues, the table is rendered properly. After the first rendering, if I refresh the page, it throws the following exception:

"java.lang.IllegalStateException: Component ID j_id_id8:studentScrollfirst has already been found in the view. See below for details...."

My JSP page looks like the follows:

code:

 
<t:dataTable
id="studentTable" 
value='#{department.students}' 
 var="student"
 border="0" 
 rows="5"

Render Response phase question
Mon, 5 May 2008 09:48:46 MDT
I am trying to find out what the specified behavior of the Render Response phase is supposed to be, and have discovered that the JSF spec seems oddly unclear on the topic.
 
Here is the question: during the Render Response phase, is the JSF Servlet supposed to call the getters for mapped backing bean properties for rendered pages, or does it get the value for the component from the in-memory component itself? Alternatively, is the behavior unspecified on purpose, giving JSF implementors the ability to do this or not, as they see fit?
 
The answer has implications for JSF application design...or, at least, some things developers will need to code around for portability. I may want to change the value in my backing bean ...

Issue with DataTable - how to control null data set?
Fri, 2 May 2008 08:40:28 MDT
I am new to JSF and just getting up to speed. Here is the issue. I am writing an app that will primarily consist of a single page. This page consists of a form with search criteris and a data table with results. I am able to get the data table and SQL to work just fine but now I am making the page more dynamic by adding the search criteria. When the page is first displayed the data table gags, of course, because no search criteria has been entered in yet thus the data set is NULL. How do I control for this? I am using a Delegate pattern with a Controller bean as my backing bean. Here is the snippet from the page that shows the data table:
 
<h:dataTable border="0" cellpadding="2" cellspacing="0"

resetting security authorization
Fri, 2 May 2008 03:42:27 MDT
Hi,
We java a myfaces application in which we have implemented security. Part is declaritive in the web.xml part is java based (used for rendering menu items, or navigation).
Now we often need to assign a role a user using an ldap tool. This all works fine but after the user is added to group/role the application doesnt pick up the new roles. We retrieve whether a user is having a role by using:
FacesContext.getCurrentInstance().getExternalContext().isUserInRole(arg0);
Unless we restart the application (appserver) the role changes are not visible. Is there a way (programatically or otherwise) to force a reload of roles the user is assigned to?
thanks and regards,
Jeroen.

Event (or breakpoint) ignored
Thu, 1 May 2008 02:44:24 MDT
Hi all,
 
I have a big problem with a JSF project developed with Netbeans 6.1 (...and also 6.0.1 is the same).
 
If I set a breakpoint ato an action_event function (for example linked to a button) of a java baking bean it is ignored, the execution (in debug mode) does not stop.
 
It is also possible that the function is not executed at all, causing the missed stop.
 
Where is the mistake(s)?
 
All thing compile and deploy ok, but ignore button clicks!
 
Please, help me!
 
Thank you

TLD for custom JSF UI component
Tue, 29 Apr 2008 12:10:19 MDT
Hi,
 
I have implemented a custom JSF UI Component that extends HtmlGraphicImage. I have introduced a couple of new attributes for my tag by specifying them in the tld file. The new attributes work fine.
 
But I also want to expose the attributes of h:graphicImage (the component I am extending). To achieve this I have copy pasted graphicImage's attributes from graphicImage's tld file into my tld. Is there a better way to expose the attributes of the base component that I am extending on the tld?
 
TIA,

Help needed in PageRenderListener
Tue, 29 Apr 2008 11:30:19 MDT
Hi,
 
I have a bean (configured in faces-config.xml and it is in session scope) which implements PageRenderListener and implemented the following method beforePageRender(PhaseEvent event) and afterPageRender(PhaseEvent event).
 
afterPageRender(PhaseEvent event) - No implementation exists in this method.
 
beforePageRender(PhaseEvent event) - Resetting backing bean values.
 
But when I debug it, I find that beforePageRender(PhaseEvent event) is getting executed 2 times. Is it the JSF behavior or something am doing wrong... 
 
Please advice.
 
Thanks,

Partial page refresh during page onload
Mon, 28 Apr 2008 17:50:16 MDT
Hi,
 
I am having problems when I make multiple PPR requests through AJAX at the time of onload of a page. This is what I am doing.
 
 
 
I have two panel boxes which have partial triggers from two different command links. So Panel box 1 has a partial trigger to command link L1 and Panel Box 2 has a partial trigger to command link L2. 
On onload of the page body I click on command link L1 and L2 which internally calls two methods on a backing bean. 
 
 
The problem I am facing is, when the backing method completes executing, it updates/refreshes only one panel. And this behaviour is very inconsistent. Sometimes panel box 1 gets updated/refreshed while sometimes panel box2 gets updated/refres...
