datatable headerClass

[Julian Ray]

Ok, so its time I addressed this issue:
 
datatable provides a single headerClass attribute which is applied to all
 elements of the table. Using text-align CSS attributes within a CSS
class allows the table header to align all  the same way.
 
So, how to align individual table header elements left, center, or right?
Using style or styleClass on the outputText in the header facet renders a
 within the  which is ignored and the  CSS styling overrides
the  stylying. Unless I'm missing something, it seems that all table
headers in JSF must align the same way wihtin a table.

RE: singleton validators and converters

Wouldn't singletons need to be multi-threaded otherwise you will get probems

validators/converters are costly to create?

Hi,

 

Is there a standard way/practice to have singleton validators and

infoSpaceTool

I have an action method that currently returns "infoSpaceTool" as String and

RE: navigation pages history...

[Julian Ray]

JV,
 
Our app keeps a stack of views. The get the previous view pop the stack and
and push the current view on to it before you return,  We also have
standardized our navigation mechanism so that each action returns the name
of the view to navigate to next and our navigation.xml file maps full view
names returned from getViewId() to JSPs. If we have x JSPs there are x
 entities. So for us, returning the view from the top of
the stack will force the navigation handler to navigate to that view. Very
simple and easy to manage.

[OFFTOPIC] MyFaces Help Wanted

[Julian Ray]

C2Glogistics is looking for one or more experienced JSF/MyFaces developers
to help us continue to develop and maintain our flagship JSF application.
Our app has been in production for almost 1 year (current version is 1.2)
and we have several large world-reknowned customers using the system. 
 
We anticipate approx 10-20 hours of work per week per developer for approx 6
months. Location is not an issue as long as efficient lines of communication
can be maintained (email, IM etc.) and sufficient overlap of the work day
for synchronous communication can be achieved (we are located in a suburb of
Boston, USA). Work will consist of enhancing our existing app through
reorganizing and enhancing existing modules, adding new modules and fixing
outstanding issues tracked through our TRAC SCM. Developers must be able to
work independently, have great communication ability, have good system
design and problem solving skills and have previously developed with the
following technologies:

*   MyFaces/Tomahawk 1.1.5
*   Hibernate 3
*   Ajax4JSF
*   Eclipse
*   Subversion/Subclicpse
*   Java Mail
*   Tomcat 5.5
*   Experience with JFreeCharts and JasperReports are a big plus.

 
We maintain database compatibility with MySQL 5 and Sql Server 2005 through
Hibernate dialects and host on RHEL4 and Windows Server 2003.
 
We will require a NDA to be signed before we provide access to any source
code repos or engineering documentation. If you are interested, or know

RE: Using myfaces for a wizard type application

[Julian Ray]

One way is to use the tomahawk saveState control. Use a single request level
bean to collect your form data. Save the bean use saveState in each page of
the wizard. If the user wants to cancel use an action which either navigates
to a page where there is not saveState (the wizard backing bean is removed)
or re-initialize the backing bean.

Okay, I'm using rowClasses with two different styles for the rows.  However,
I'd like to implement a highlighting scheme based upon onmouseover and
onmouseout.

onmouseover is easy enough, simple javascript to set the class to the class
that handles the highlight.

The onmouseout is the tough one though.  Ideally it should be as simple as
using javascript to set the class to the appropriate row class.  If I were
generating the HTML directly I could easily determine which row I'm on and
use the appropriate class for the row.

Anyone have some suggestions as to how I would do that in JSF?

RE: Combine Hibernate and JSF, but how?

[Julian Ray]

Hi 
Matthias
 
Here is what our class heirarchy 
looks like. I'm still in the process of documenting and refactoring it but you 
should be able to get the general idea. We use the threadlocal pattern for 
managing Hibernate sessions and transactions. All this detail is provided in the 
AbstractUIBean which provides all services for managing page state, 
materializing Hibernate objects and managing transactions, getting session beans 
etc. The Page and Table abstract classes provide utility methods for manaign 
individual instances or lists of Hibernate objects.  We also have a class 
of hibernate-aware converters which know how to convert primary and 
foreign -key values of objects into correct domain values for the 
view. 
 
Hibernate itself is initialized via 
a filter and preloads as many objects into the second level cache as is useful 
on app start.
 

 
An implementation with 
respect to a single class of business objects looks like this. Each interface 
(Deletable, Searchable etc.) uses a JSF fragment which is included into the JSF 
page. Our JSF pages are heaviy templated with lots of includes for all common 
groups of attributes of our business objects.

Re: Scheduler: Getting Clicked Entry

[Julian Ray]

Ok, so I resolved this issue.

When clicking on a schedule item the scheduler saves the selected state
(i.e. which schedule entry was clicked) into the schedule model then submits
the form. My problem was the model was in request scope and the state is
lost between requests so when the form is posted and the backing bean
re-generated the model was getting re-generated and, therefore, loosing the
state. The resolution: keep the model in request scope but save state across
views using t:saveState.

I purposfully did not want to do this as the model represent highly dynamic
data and I wanted it refreshed on each re-post. A better design (for my
purposes) would be to extend the scheduler to allow it to get/set the
selected item id (which could be preserved in view state) while the model
itself dynamic.

Re: Scheduler: Getting Clicked Entry

[Julian Ray]

Hi Jurgen,

I'm back on this and still have not found a resolution.

Looking at the code, example 5 does not return the selected entry but simply
identifies that an entry was clicked in the mouse listener and the action
method simply returns "success".  Am I missing something here?

Has anybody else got this working and if so, have any code they can share.


BTW, I am not using facelets.

Thanks
Julian

You are probably better managing the backing bean in the session in that

Hi everyone,

On page X I have a saveState tag to preserve the state of a backing bean
between requests.  There is also a link on the side navigation bar that is
used to navigate to page X.  Whenever a user clicks this link, I do not want
to de-serialize the backing bean but rather I want a new instance of the
backing bean to be created (just like it is the case on the original load)
Is there any way to do this (for example to somehow overrides the behavior
of the saveState tag in such  case).  Perhaps someone can explain the
internals of the saveState implementation; that would be really helpful. 
Thanks in advance.

RE: wizard-style JSF application: looking for words of wisdom

[Julian Ray]

We have several of these in our app and have a consistent approach using
just Tomahawk. Each page of the wizard has a different backing bean (request
scope) which inherits from a wizard class which manages forward/backward
navigation etc. and access to a wizard-specific bean to store state. The
state bean is managed using Tomahawk's saveState tag.

The model works well and is very efficient. We use it for creating new
objects as well as editing existing object -- you just have to be careful
about how to initialize the state bean on the first page and managing page
access such that the user could not type a URL to page n unless page n-1 has
been completed.

Yes, you can also use sandbox` conversation component to achieve a wizard.

In the current application i am developing on, we use t:savestate in order
to get a page-wide scope for our beans. The beans are special page-wizard
beans which get a base wizard functionality from a wizard base class.

The typical back-forward-end functionality works very well with this
solution.

Hi all
I use JSF some months now. But what I really miss is a nice LayoutManager

It would be so great if one could use JSF like this:

  
  
  
  


Same for Border:

  
  
  
  


Or the like. You know what I'm talking about. Is there any easy way to do
this? I don't think it would be nice to use 's with CSS...
If so, great. If not, I'm really thinking about to create a custom component
that can render all other JSF elements, but which is able to handle some
basic layoutmanagers.

Summary:
Flowlayout: would be very easy to do
NullLayout could be done using html tables and some wierd hights and widths
BorderLayout: could be done using html tables and col/rowspan
GridBagLayout: could be done using html tables and col/rowspan
GidLayout: just a simple html table

Any feedback?

Thanks,
Remo

There are some implicit variables to simplify accessesing objects in session

#{sessionScope.foo.bar}

Or

#{applicationScope.foo.bar}

I haven't tried this for navigation as you've described, but it works great

Automatic Page Refresh

[Julian Ray]

Has anyone managed 
to get a JSF page to automatically refresh. Using meta tags is out because the 
URL lags behind the actual view in the browser so it refreshes the previous 
view.
 
I would think that 
you could add a timer and refresh current view using _javascript_ and a 
hidden submit button attached to a backing bean action but before I start to do 
this I wanted to check to see if anyone has already done it (perhaps more 
elegantly) and could share code. It would actually make a cool Tomahawk 
component if it could be encapsulated in a custom tag.

Perhaps a good strategy would be to add bindings to all the form elements
you need to validate and a hidden form element at the bottom of the page and
perform a backing-bean validation on this hidden element. You can validate
all the values in the bound form elements at one time and as complicated
business logic as you need.

Hello,

is it possible to handle partial validation of form content? I need 1 or
several items in a forms to be valid at a specific submit, but as it is only
a request for partial change in the form, it is most probable the rest is
not valid / finished. However, i need to keep information in rest of form
even if it's not valid.

Here is how my form must look like:


data1 [.]
data2 [.]
data3 [.]
  subdata1 (read-only)
  subdata2 (read-only)
  subdata3 (read-only)
  subdata4 [..]  [add-subdata-button]
data4 [.]
data5 [.]
[submit]

when i click add-subdata-button, i need subdata4 to be validate, but textual
content of data 1 -> 5  must be kept without any validation attempt.
when i click submit, data 1->5 must be validated, but content of
subdata4 ignored.

I suppose the JSF framework has something for this, but am not sure what.

RE: 'dynamic' breadcrumb navigation --> possible?

[Julian Ray]

Hi Kuni,

We have a solution which does exactly what you want. However, it requires a
bit or organization of your JSF files. In particular:

A session-scoped stack to store previous views 
A view-specific mechanism to push each new view to the stack
A standardized means to associate a view name with jsf page
A component to dynamically render the breadcrumb trail and
A backing bean to manage breadcrumb actions.

We have not yet had time to create a JSF component to encapsulate all this
coding but, if there is enough interest from the MyFaces community at large
I will try to put our methodology on the WIKI for you and others.

Subject: 'dynamic' breadcrumb navigation --> possible?

Hello,

i'm looking for a breadcrumb component.. i found the navigationPath
component provided by trinidad.. that's really nice but that's not what i'm
looking for! i imagine something like these:


which will render:   index >> page1 >> page2 >> page3

the component 'knows' your navigation history based on the navigation rules.
in the simpliest way you only should define an entry point. the component
observes your behavior to create a path like shown above. no path definition
is needed..

a well known strategy to create such path is to organize your sources in
structured directories and parsing the directory tree.. but that makes no
sense cause your source-tree depends on the navigation-path terrible ;)

anybody has a working example or knows hot to realize it? ..

Greetings,
 
I am having tons of problems 
migrating a pure html table to JSF, I don´t know if I am still not used to think 
in JSF terms but I kind of get the impression that table components in JSF miss 
lots of features that were present in html.
I enumerate 
some:
 
1.  How is it possible to 
associate an image to a td as background in JSF:
Example in html:  
 
2.  How is it possible to 
define an empty td with certain width:  
Example in html:  
 
3.  How is it possible to 
specify to a panelGrid container that a bunch of elements must go under a 
td?
 
Does anyone knows of a table 
component in JSF that is more closely related to the html 
table?
 
Thanks a

hello to everyone,

I have a form that displays detail data from a backing bean.

The same bean supplies properties for an update page.

The update page has a Cancel button and when selected should return the user
to the detail page with no changes saved.

Simple enough use, but when the Cancel button is selected, the backing bean
is updated and the detail page shows modified data.

How do you folks handle similar situations?

Thanks in advance for your help.

Subject: Component tag with variable componenttype, howto?

Hello,

I am in a situation where i need to write such a tab:



The jsf component is to be created using parameterBean.createComponent
().

My first thought was to create an empty Component whose sole role was to ass
the result of parameterBean.createComponent() as it's only child. 
However, i begin to think it might be better of the tag itself would call
createComponent() on my bean, this would prevent creation of useless
intermediate Components. But i am not sure how to do this, according to my
knowledged, i need to extend UIComponentTag and this requires to return a
componentType, which in my case is a non sense as the component is to be
generated by createComponent() How can i do this. Am i forced to create
a custom component that would only serve as an container to another
correctly fitted component?

I hope i was clear in my request :)

Thanks for consideration,

RE: JSF-RI, ADF, MyFaces, Facelets. I'm lost.

[Julian Ray]

Our project started off using Suns Creator which is JSF-RI + a few
additional components. We quickly found 
the MyFaces + Tomahawk provides a much better option and moved our entire
project suite (6 apps) over to it. I purposfully stayed away from ADF when
making a choice as it still belonged to Oracle and after spending 4 years
banging against stupid Oracle bugs in my previous company, I just didn't
trust their quality control (I'm glad to see its now open source). We did
look at Tobago but didn't want to replace the view controller and it seemed
to have a small developer group.

Here are a couple of key points to consider when making a selection: 

[1] the learning curve is pretty steep in all JSF implementations and, in
some cases, the richer the component choice, the more learning needs to be
done and the less documentation is generally available. 

[2] user-group support is *very* important. Both MyFaces and Sun have large
user bases and active user lists but perhaps its worth while spending a few
minutes browsing through the forums to get a feel for (a) the type of
problems user experience, (b) how helpful (and fast) is the user community
in reponding to questions, and (c) how reactive is the development team to
addressing Azissues?

My money is firmly on MyFaces -- great support, great components and a great
product.

They are not concurrents. MyFaces provides a JSF implementation (as the Sun
RI does), while ADF Faces/Trinidad is a library of components with some
added services. If you are talking about "MyFaces Tomahawk"
, then yes, there is some overlap with Trinidad, but they are probably going
to be merged in future.

Right now, you will have some troubles only using both Tomahawk and
Trinidad. For example Tomahawk components will not be aware of Trinidad
skinning system and of its client validation framework. I think that it is
better to choose one of the two until they'll be merged or refactored to
work well togheter.

Subject: "Process" scope

Hi.

In web applications, it is often desirable to have a "process" scope of
beans. 
Process-scoped beans are retained between sessions, but in contradiction to
session scope there can be many of them per session. An example of process
scope scenarion is a document deletion:

select document -> display backup options page -> display deletion
confirmation page -> congratulate that the document is deleted

During the deletion process you somehow need to keep track of the document
that is being deleted.
You can't model that with a request-scope bean since this will be lost in a
multiple-step process.
You also can't model this with session-scope bean since if the user tries to
delete several documents concurrently, you'll get into trouble.
Therefore you need a "process"-scoped bean. There'll be one instance per
initiated process, but these instances will not be lost across requests.

Are there any existing approaches to process-scoping that could be used with
MyFaces?

My idea was tracking processes with an URL parameters and use a custom
variable resolver (+ Spring maybe) to instantiate beans on a per-process
basis.

Bye.

RE: Dynamically adding row in datatable.

[Julian Ray]

Why not create a list in your backing bean to store the rows. Add the
backing bean to session scope or (a better approach) use the t:saveState tag
to store the list in the request.

Hi,

   I am having a datatable with no of rows. For every row i have a button
and username, password, etc fields. Now when i click on the button of any
row. one blank row should be added next to that that row.

Here, conditions can be he can click on more then one button without adding
data.
Data can be save only when he clicks on the save button given at the bottom
of page.

How can i achieve this.

RE: AbstractUIBean class - where to find?

[Julian Ray]

Actually, the AbstractUIBean is a base class which is not part of the
JSF/MyFaces/Tomahawk framwework but is part of our own implementation and
provides basic functions (such as session participation, messages etc.)
which all our managed beans use.

RE: Dynamically adding tabs to t:panelTabbedPane

A simple way would be to create a container such as a h:groupPanel for each
tabbed pane in the JSP and use a binding to it in a backing bean, then add
to the panel from the backing bean.

Hello,

one question in this context:
How do you add content to the tabs? Programmatically, or do you refer in the
JSP page (in case JSP is used) to the created tabs?

RE: How to displayi an images generated by a managed bean?

[Julian Ray]

Hmmm, let see...
as many of our charts require different params, as well as some core params
to be sent, we naturally end up duplicating a lot of code in the backing
beans. Even refactoring this code into base classes did little to help. This
duplicated code has as couple of negatives: [1] its duplicated, therefore,
inefficient for many reasons, maintenance not the least among them, [2] the
URLs and servlets we create need to be on the same lifecycle which is not
necessarily the same as the JSF pages and backing beans -- we reuse the
servlet across several JSF services, and [3] as we extend the charting
functionality there is a lot of unnecessary testing and code changes which
is minimized if the backing beans work against the custom component api.

Lastly, its cleaner and much more JSF-ish :) 



Typically, as in most designs, if your problem is not too complex, a simple
solution will work fine (eg servlet and URL). As the problem complexity
increases, however, more elegant solutions are necessary hence the custom
component. Indeed we started with backing bean URLs then migrated to a
custom component during the course of several code refactoring phases - a
pattern we repeated for JasperReports and other functionality as well.

To address Cagatay's comments: 

[1] A phase listener would probably be preferable to a servlet and I intend
to migrate (or at least benchmark) a phase listener to replace our servlet.
However, often when beginning with a new technology staying within the
bounds of our experience at, least initially, can be beneficial, especially
when using an agile approach to development where speed of development and
delivered functionality are driving forces. Basically, if you know how to
code servlets and are comfortable coding servlets, use a servlet and when it
all works migrate to something better but get it to work first. 

[2] I have not yet tried the JSF-Chart Creator in JSF-COMP although I have
heard good things about it and fully intend to take a look. However, this
goes back to my initial rant and if JSF-COMP does everything you need (at
least for now) why not use it -- it was not available when we started our
current build cycle :).

a custom component to provide the JSF interface as we
use charts on a large number of our pages and it fits the MVC model better
to let the JSF fuly control the format and display of the greaphic.

RE: dataTable get datas from multiple table

[Julian Ray]

A couple of thoughts

[1] Use a join to get a composite row back from the database which contains
the complete set of data you need
[2] In your backing bean create a set of methods to get the required column
data from whichever table it exists in This can be done as follows


 


And in your backing bean create a method like

Public String getRefLanguage() {
String Name = getValue("#{rowRecord.name}");
// Lookup in the database for this users language
//
String lang = .
return lang;
}

RE: LoginAction not executed after server restart

[Julian Ray]

Hi Michael,
 
You might want to check to see if your login page is 
entering into a session. When the server restarts and the same page has not been 
refreshed in the browser it might be associated with a stale session. When the 
browser refreshs a new (and valid) session will be created. Two ways to get 
around it (a) allow Tomcat to save sessions between restarts and  (b) don;t 
let your login page start a session.

Sent: Wednesday, June 28, 2006 4:53 AMTo: MyFaces 
DiscussionSubject: LoginAction not executed after server 
restart


I have a standard login page with 
two input fields.
The corresponding BackingBean has 
Request scope and a login-Action.
 
Now I'm facing a (for me) strange 
behaviour:
The login page is displayed without 
any values.
Now I restart Tomcat (happens often 
during development).
When I enter values and execute the 
login action then the login page is displayed again without any 
values.
The loginAction was not 
executed!
So I have to enter my values again 
and login again and then the login action is 
called.
This occurs only if Tomcat has been 
restarted.
 
Why is the login action not called 
after the first submit?
The backingBean has request scope, 
as I mentioned before.
 
I use server side state 
saving.
 
Thanks for any 
help

I don't think that there is any direct way you can change the column class

I want to create list of commandButtons based on a collection of
ActionObjects. so I want to loop over my collection of this.
But I cant seem to find looping constructs in JSF except from the DataTable.

Does  work or how do I mix it with Java constructs in a JSP file

thanks for any hints

RE: Typical Validation Issues

[Julian Ray]

You can always create a hidden input element at the bottom 
of the form which has required="true" and perform form-scoped validation using 
the backing bean. 
 
The spec says that form elements are processed in the order 
they are on the page so putting the hidden element last means that it will be 
validated after any other validations you specify. Note that if you need to use 
tag-level messages you will need to invalidate each component by getting it from 
tree or by using a binding.

Thanks for the code.  The problem though is if I leave the 
required="true" attribute on the input field, even with the custom validation, 
the commandLinks still trigger the validation.  If I remove 
required="true" from the input field, and I try and add a category without 
typing in a category name, no validation occurs. And I've 
simplified the validation for testing purposes. public void 
validateCategoryName(FacesContext fc, UIComponent uic, Object 
o)    {    if 
(currentCategory.getCategoryId() == 
null)    
{    
((UIInput)uic).setValid(false);

Hi!
> I am having the same old issue with exception handling that has been

First, to get rid of the "blank page" problem it should be possible to use a
servlet filter which buffers the whole response (also ignores any flush).
This might slightly increase the latency, but if you use e.g.
the ExtensionsFilter this buffering already takes place.
You do not have to do any further processing of the response, so the
response time at all shouldn't increase that way.
Again, if you use the ExtensionsFilter and NOT the StreamingAddResource this
buffering already takes place, so there should be no need for this filter,
except you have huge parts of jsp/html outside your f:view component.

Second, I use the web.xml strategy too. So adding

500
/error.jsp

do the "friendly error page" trick.

At last you might get a copy of error.jsp from tomahawks "simple"
example (tomahawk/examples/simple/src/main/webapp/error.jsp) there you will
find the code required to get the real exception (which is not that easy as
it might sound - well, ok, if you know the trick its easy again
;-) )

RIP ugly exception page.

Right?
2) Can a ListDataModel take a 'typed' ArrayList as argument?
 
I had bad experiences with Sun Creator not supporting JDK1.5 external

RE: jsf-comp OptionalValidation

[Julian Ray]

What is the scope for your backing bean? It probably needs to be request
otherwise it will only be craeted once. Also, how are you calling the method
which creates the view components? If you call it in the constructor it will
get built too early so you need to find some way to build the components on
the page. With the panel grid I found that the best time to call is when the
panel grid is requesting some other value such as the number of columns.

I was looking into the code of the optional validator, and was wondering if
it would be much better placed in JDK 1.5. Instead of creating
"optionalValidator" tags with embedded validator IDs, it could use JDK 1.5
proxy classes as Validator and StateHolder are interfaces.

Then, the proxy could catch all ValidationExceptions from validators and do
what it needs to do. The developer would not need to change their view code
at all. With facelets it should be relatively easy to build a tag handler
that would create the proxy from the real validator.

Just an idea

RE: Dynamically Changing Panel Grid

[Julian Ray]

Hi Daniel

Here are a couple of things you could try

[1] Your page includes all the components but you use the rendered=""
attribute on each panel using EL or a backing bean to determine if a
particular panel should be rendered

[2] Dynamically create the contents of the panel using a backing bean and
adding components directly to the panel via a binding.

Subject: Dynamically Changing Panel Grid

Hi There,

I have a situation where I want to switch between different panel grids on
the screen using a drop down.  So essentially I have one component bound to
the screen, and in the backing bean I want to change what that component
actually is.

This however is causing me much grief, as it seems JSF only reads the
bindings when it first renders the page.  Is this correct?  No matter what I
can't seem to be able to get it to change to another PanelGrid once its been
rendered.

Does anyone know how to best approach this?  Have I missed something crucial
here?

Thanks,

Daniel

RE: Can Sandbox components be used in production app?

[Julian Ray]

We use sandbox compoenns but to control the process we have 
the sandbox source and compile the sandbox ourselves -- on our schedule. This 
way any issues which show up can be dealt with and we can debug. Changes to the 
tomahawk or sandbox components are downloaded from svn and tested before they go 
into to our app.

I would not recommend it, however I do so myself for some components. 
Obviously bad things can happen, the scope of which is impossible to predict. 
Remember that when components get "promoted" from sandbox to tomahawk, you will 
have to change the namespace on your .jsp / .jspx sources.
