RE: browser back button in JSF?

[Yee CN]

There was a benchmark posted around a month ago - the finding was that state
saving in client runs a lot slower than state saving in server.

Is there any update this?

RE: migrating to Facelets

[David G. Friedman]

You 
will probably have to change any jsp taglib entries to html namespace entries so 
instead of:
 
<%@ 
taglib uri="http://java.sun.com/jsf/html" prefix="h" 
%><%@ taglib uri="http://java.sun.com/jsf/core" 
prefix="f"%>
... 
etc 

 
You 
would need:
 
http://www.w3.org/1999/xhtml"    
xmlns:f="http://java.sun.com/jsf/core"    
xmlns:h="http://java.sun.com/jsf/html"

something like that.

RE: savestate question

[Tom Butler]

Found the problem here.  On the second
page, I also included  a t:saveState tag for the backing bean from the
previous page (page that linked to second page):



 

I must of missed this somewhere, but also this did
not seem obvious.  It seemed logical that if I used  on
the first page with the backing bean, that when I linked to the second page,
and then came back to the first page, then the object would be read from wherever
it was serialized to.  Having to place a  on the second
page (to save the state for the same backing bean from the first page) does not
seem to make sense?  Why would I need to re-serialize the bean again on
the second page?  Anyways, if this works I’ll leave it as is –
I’d just like to understand the ‘why?’.

Within .jsp page I use t:saveState to save the

t:saveState works to some degree, because when I
remove it, t:datascroller can not display the datamodel (property on backing
bean) when I scroll from the first page to the second page - with t:saveState
enabled, this works.

 

However, when I leave the page with the t:saveState
to another page, and then come back, the backing bean data has not been saved.
 

 

The backing bean does implement the Serializable
interface (the only addition I have made to the class is adding the
“implements Serializable” on the class definition – I did not
add a serialVersionUID variable or anything else?):

public class SearchIspBean extends SortableList implements

In my special case, the rendered code has to go to the JTidy filter of
UPortal, which transforms the HTML code to XHTML (AFAIK). I don't know if
JTidy is capable to transform incomplete HTML pages...

Hi!


When I set the column number of a HtmlInputTextArea, e. g. to "10", only "6"
columns are displayed. Entering more than six characters causes a line
break.
I experience this behavior in IE 6.

In Firefox 1.5, there are rendered "10" columns as expected, but "2" rows,
although I set it to "1" row?


In the source code, the textarea looks like this:




Is this a browser problem or a JSF problem?

BTW: Accessibility guidelines require that the font size can be changed by
the user, e. g. by changing it in the browser, but this is not possible in
my case (in MS IE), regarding the font used in the labels. I really need to
overwrite this behaviour with a CSS class...

Re: JSF+Hibernate

Dave schrieb:
session.merge is not very smart. Hibernate will update all properties

Is there a better way other than merge?  Thanks.


Not really that is one of the downsides of using an orm mapper, you will 
get some overhead regarding queries and data, you however can limit the 
data written by adjusting the hibernate parameters (probably pushing 
some of the association stuff into the lazily loaded domain might help, 
adjusting the fetch, depth as well)


If you want finer granularisation than that, you have to go the manual 
route and merge manually property by property (the beanutils can help in 
this case)

RE: returning to same position within a datascroller?

[Tom Butler]

I figured out a way to do this, so I’ll post it in
case anyone else needs to accomplish this same task:

 

1. Page displaying DataTable with DataScroller to scroll
through large result set:

 



 
rowIndexVar="rowindex" 

 
rows=”#{backingbean.displayrows}” 

 
first=”#{backingbean.pageindex}”

 
rendered="#{backingbean.datamodel.rowCount > 0}"

 
…… (snippet only)

 

//  command link to link to details page for selected
row






 
//  update pageindex property on backing bean with rowindex var from the
datatable when commandlink is clicked






 



paginatorMaxPages="9"
paginator="true" 

rendered="#{backingbean.datamodel.rowCount
> backingbean.displayrows}">

 

 

2.  Backing Bean
for Page displaying the DataTable (session scope)

 

private int pageindex;  // keep track of page index
within datascroller

private int displayrows;  // number of rows displayed
in datascroller

 // constructor

 public BackingBean() {

    pageindex = 0;   // set initial
page index to zero or first row in backingbean.datamodel

   displayrows=10;    }

 

// getters & setters – setter for pageindex is one
of interest

//  setPageindex example:  displayrows=25; current
rowindex =6;  ((62/25)*25) = 2*25 = 50 (first row of datascroller)

public void setPageindex(int rowindex) { 
this.pageindex = ((rowindex/displayrows)* displayrows);  } 

public int getPageindex() { return pageindex;  }

public int getDisplayrows() {  return displayrows; }

 

 

3.  Detail page
(linked to from page containing datatable)

//  when return to datatable page, will be placed at
same position within the datascroller

  // navigation specified in faces-config.xml

Is it possible to return to the same position within a
datascroller after leaving the page and returning (i.e., datatable displays a
large result set; user has scrolled through the data and is on the 3rd
page of data; user selects a record which links them to a detail page; now want
to return the user to the original .jsf page at the same 3rd page of
data within the datascroller)?  If so, how?

Re: Sandbox Schedule Component to Tomahawk?

[Martin Marinschek]

Sandbox doesn't mean we think this component is just for playing 'round.

Actually, some of them, e.g .the schedule is production stable.

Caveat: we're allowed to change the API at any time here, without
warning, and this is what we leave open by letting it in the sandbox
for now ;)

Martin

behaviour change upgrading to nightly build

[Thomas Gaudin]

Hi,

I have just upgraded a maven build from about 10 days ago to the
nightly build available on myfaces website.
I am using a custom authentication method in a request scope bean.
The code for the logout() method is performing the following :

    getRequest().getSession().invalidate();
    Cookie terminate = new Cookie(
   
TokenBasedRememberMeServices.ACEGI_SECURITY_HASHED_REMEMBER_ME_COOKIE_KEY,
null);
    terminate.setMaxAge(0);
    getResponse().addCookie(terminate);
    return "welcome";

The "welcome" refers to a navigation rule in my faces-config.xml :

    
        /*
        
            welcome
            /home.xhtml
            
        
    

Before upgrading it was working fine but now I get this exception (I
translated in english the message):

java.lang.IllegalStateException: Not possible to create a session
after the response has been sent
    at
org.apache.catalina.connector.Request.doGetSession(Request.java:2206)

    ...

If I add a "getRequest().getSession(true);" before returning this
solves the problem but I am worried about this change.
Would anybody have some hint about what is the matter please?

Although even though what i was doing was wrong design wise  it still shouldve worked ... coz i hadnt overwritten either encodeChildren or encodeEnd. Anyway thanx a lot dude ...

Re: Collision of session object and h:dataTable "internal variable"

[Mathias Brökelmann]

The var attribute is only available when the table renderer renders
the rows with the data. the rendered attribute is evaluated before the
rows are rendered. The table renderer requests the rendered value of
each column for the header and footer cells which are rendered without
the var attribute is set.

It will not work when you rename the var attribute. Each attribute of
h:datatable and h:column (including their facets header and footer)
can not be made dependent on the var attribute. Only the additional
defined row-specific attributes of t:column can depend on the var
attribute.

Error when using "spread" layout in programmatically created HtmlSelectOneRadio

[Matthias Kahlau]

Hi!


I used "spread" layout successfully with HtmlSelectOneRadio and
HtmlSelectManyCheckbox in JSP. Now I programmatically created a
HtmlSelectOneRadio and set the layout attribute to "spread":

HtmlSelectOneRadio radios = new HtmlSelectOneRadio(); // Tomahawk
  selectOne = radios;
  this.form.getChildren().add(selectOne);
  selectOne.setId(id);
  radios.setLayout("spread");


When the view is rendered, I receive the following error:

2006-02-05 12:43:56,921 ERROR
[org.apache.myfaces.renderkit.html.HtmlRadioRendererBase] Wrong layout
attribute for component _id0:Frage_2: spread


Why do I get this error? (I need spread layout...)

Re: AW: document.getElementById("jsf_tree_64") has no properties

[Volker Weber]

Hi Haihua,

the state saving method is defined as context-param in the web.xml:



  State saving method: "client" or "server" (= default) See
  JSF Specification 2.5.2

javax.faces.STATE_SAVING_METHOD
server


Seems i was wrong saying client is the default :-(.

AW: document.getElementById("jsf_tree_64") has no properties

[Haihua Luo]

Hi Volker,

thank you for your reply! You are right. The hidden input field "jsf_tree_*"
cannot be found in the generated html page. But how can I switch to
server-side state saving?

Thanks!

Betreff: Re: document.getElementById("jsf_tree_64") has no properties

Hi,

this may be a portlet problem? I don't know mutch about portlets, but
afaik the portlet rewrites the ids to ensure they are unique.

When using client-side state saving (which is the default) there are two
hidden input fields "jsf_tree_64" and "jsf_state_64" in which the state
is stored.

Try server-side state saving if you can.

  Volker

Re: Redisplay Problem

Hi Francesco,

> ... the AccountBean is in request-scope

thats the reason for recreating this bean every request ;-).

You can hold a request-scope bean over multiple requests using the
t:saveState tag: 

See: http://myfaces.apache.org/tlddoc/tomahawk/t/saveState.html

Re: Panel Grid custom component

[Volker Weber]

Hi Ali,

UIPanel for base class should work, did you overwrite encodeChildren()
or encodeEnd() to do nothing?

BTW: don't expect these components between your rendered start and end
comments, they are just created here, the rendering is done in
encodeChildren() method of the superclass.

Just for make sure that my suggestions are correct i had implemented
this myself, extending HtmlPanelGrid.

See attached sources and working example at:

http://weber-oldenburg.dyndns.org/myfaces-example-simple/myPanelGrid.jsf

Regards,
  Volker

Redisplay Problem

[Francesco Persico]

viewAccount.jsp
			
			"id" value="#{AccountBean.id}">
			"#{AccountBean.id}">
			"#{AccountBean.username}">
			"#{AccountBean.email}">
			"#{AccountBean.firstName}">
			"#{AccountBean.lastName}">
			Account Roles:
			"#{AccountBean.roles}" var="role">
			
			"#{role.description}">
			
			
			"#{AccountBean.removeRoleAction}">
			"Remove" >
			"roleName" value="#{role.name}">
			
			
			
			
		
after the AccountBean.removeRoleAction is finished the method 
return "success" and the page is redisplayed but the outputText fields are all 
blank in exception of id(i have the inputHidden field) because ,from a debug, it 
seem that a new AccountBean is created :( how can i redisplay the same account 
of the old request? the AccountBean is in request-scope because i am the admin 
of the web application and i am managing the roles of other registered 
useri hope someone will help me, tnx
