Re: [newbie] embedding HTML links

So the JSF renderer seems to insist to always translate the special
characters of HTML (like < into < and so on)

How do I switch that off?

Or is there a better way to embed links like that into JSF pages?

Btw. the link itself is contructed in a backing bean as string so I can't

Re: java.lang.NoSuchMethodError: .DummyFormUtils.isWriteDummyForm...

[Joey Geiger]

Is the state saving issue going to be back ported to 1.1.3 and released 
as some kind of patch?


I'd like to have that fix, but I still need to maintain the 
linkDummyForm functionality since my pages
currently make heavy use of it. The application is in "release" and I 
can't re-write all pages right now.

It's being worked on now.   We'd like to do a MyFaces core and a
tomahawk release fixing this bug and the server-side state saving
issue as soon as it's fixed.

You're already involved :)   If you're not already subscribed to
myfaces-dev, you can do that.   The example code you posted below
provides a great test case.

You can do a search for DummyForm on the MyFaces users and dev mailing
list over the past couple of weeks to catch up on the topic.

Also, postings about commandLinks and commandButtons for the last four
weeks are probably also appropriate.

TOMAHAWK-416 is where the issue is officially being tracked.

The best thing you can do (short of providing patches yourself) is to
keep testing the latest svn code against JSF RI 1.1 + Tomhawk, Myfaces
Core by itself, and MyFaces Core + Tomahawk, and telling us when all
three combintations are working without error.   At that point, we can
do a release.

Myfaces core parses the config file once as normal.

Then Tomahawk parses it a second time (although it's only looking for

Error while displaying an image inside of facelets .xhtml

[Joey Geiger]

I've had this error thrown on a couple of pages, but not consistently 
every time. I believe it is
happening because I am using PNG images in certain places, but list 
isn't supporting that mime type and
the browser that is looking at the page cannot render PNGs, and thus 
this error is being thrown.
Am I correct in that assumption, or is there something deeper I need to 
start looking for?
Also, is there a way I can get log4j to ignore this error specifically 
so my logs don't start to fill up?


Thank you.

JSF/Spring/Hibernate Thread Safety questions

[Joey Geiger]

Sorry if this is a bit too general for this list, but as I'm using 
myFaces as my JSF implementation I thought it would apply.


I've recently written an e-commerce application using 
Facelets/JSF/Spring/Hibernate/Tomcat/MySQL with a shopping cart, 
customer sign-in, etc.


As this is my first "real" application, I was wondering if there are any 
specific places within my application that I should be concerned about
thread safety. I think I've been going under the possible mistaken 
belief that since most of my processing is done in Tomcat's sessions, 
and objects are
stored in those sessions, I'm pretty safe. Are there any specific 
sections I need to be more aware of than others? (Customer sign-in, 
saving an order?)

Also, I'm using a connection pool setup as a JNDI resource in Tomcat.

Any help would be appreciated. Thank you.

Re: What to do when form depends on querystring params?

[Joey Geiger]

My solution was to use javascript redirecting on the page.

The backingbean had a value Valid, and if isValid was false, the 
javascript redirect rendered at the top of the page.


Messy? Maybe, but it does what I need it to do.

Re: JSF can handle GET requests *just as easily* as other frameworks

[Joey Geiger]

You can pass get requests, but you lose the current state of the 
application.

I have a setup that uses a URL like /product/product.jsf?prodid=1234

product.xhtml (partial)
...snip...


rendered="#{not productPageBean.found}" />

...snip...
#{entity['title']}
...snip...

ProductPageBean.java (partial)
protected void init() {
this.productid = FacesUtils.getRequestParameter("prodid");
this.product = dao.getProduct(this.productid);  
}


FacesUtils.java (partial)
public static String getRequestParameter(String name) {
return 
(String)FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get(name);

Re: Clientside statesaving and linkDummyForm

[Joey Geiger]

I was running into the same issue. I switched to server side state 
saving, since I think the

issues with the back button have been fixed(?).

Another option would be to have one large form surround every page, but 
I don't know how

correct that is. It would also make validation an issue.


Mads Henderson wrote:

Hi,

We are using client side state saving and are having some problems
with the amount of data sent to the client.

It appears that all forms on the page contains a hidden input field
containing the (same) object representing the state. One form
linkDummyForm is always present, and then of course also the forms we
declare in the jsp pages.

It seems unnecessary to have the same information in all forms, is
there a way to avoid that?

Is there a way for me, in the cases where I need to declare a form for
some input fields, to make use of the linkDummyForm that is generated,
in order to avoid duplicating the state object all over the generated
html?

Thanks

Re: No Javascript again???

Are you using the very latest version snapshot (or test release) of myfaces?

There is a bug in myfaces core which prevents the dummyForm to work. I

Ciao,

Re: No Javascript again???

[Joey Geiger]

I tried it on my system and it worked in both cases.
If I use your exact code, the form renders properly, and the enclosed 
link uses that generated form as expected.
If I remove your form tags, myfaces properly creates the dummyLinkForm 
for the link.


Are you calling the page directly? (http://server/test.jsf) or do you 
have an index page that redirects to the page (http://server/) which 
calls an index.jsp which forwards to test.jsf,
leaving the location as (http://server/) even though test.jsp is 
displayed. My problems happen in the second case.

Re: linkDummyForm not rendering on every page

I've found it has something to do with the need for an actual page to be

If the browser is showing www.site.com/ or www.site.com/admin/ it fails.
With www.site.com/page.jsf, the link dummy form will render and the
