There is a lot of buzz (not only recently) around some extra scope, that is shorter than a session and longer than a request. Such a scope is a very good scope to implement business processes or some wizard (==> step x of n). Lots of frameworks call this “conversation”, so does Orchestra or Seam. In Trinidad there is a “pageFlowScope” for this…
One of the goals of JSF 2.0 is to “standardization of the many different Dialog/Conversation/Scope/Flash... more »

While out-of-the-box confirmation dialog is not yet available in RichFaces, I will show you how to build one. Tomorrow I will show how to make it more reusable by packaging it as a Facelet custom tag.
If Cancel is clicked then nothing happens. If OK is clicked then the value is... more »

In JSF there is no concept of client-side conversion and validation. All is done on the server, which means you notice some extra round trips in case there is something “wrong”. Eventually JSF 2.0 will change that…
In the meantime there are some frameworks that provide help. One of them is Apache MyFaces Trinidad.
The basic idea of Apache Trinidad client conversion and validation is that it works on the client in a very similar way to how it works on the server, except... more »

Did you ever need to set a focus on a particular component after a request? In RichFaces, you can set the focus attribute to point to an id of a component to which focus should be set after the request. All components that send an Ajax request to the server have this attribute. Using it is very simple, here is an example:

RichFaces comes with the following skins:

To use a skin, all you need to do is set the name in web.xml file:
<context-param>
<param-name>org.richfaces.SKIN</param-name>
<param-value>ruby</param-value>
</context-param>
Suppose you like the skin, but you want to make some small changes to it. Here is what to do.... more »

Most common pattern, when doing logging, is currently this:
if(logger.isLEVEL()
logger.LEVEL(.......);
Some could say, that these checks “blow” up the code… But what if the LEVEL(…) call itself would check the “isLEVEL()” ? The code would be a little bit cleaner, isn’t it ?
logger.LEVEL(.......);
Our internal logger does this, and I ran into the pitfall But we still do (sometimes) check for the log_level, before calling... more »

I saw a reference (http://mkblog.exadel.com/?p=115) to my blog on one of the Brazilian JSF forums. I translated the thread using Google and it looked like someone was asking how to create RichFaces tabs dynamically. So, here is quick example.

One more update on the book. Since I last blogged about the book, some changes happened. Originally the book was supposed to be available early September as firstPress book. Because I ended up with way more pages than a firstPress book can have (I guess it’s good), the book was “upgraded” to a standard Apress book. What this means is that a hard cover version will be published closer to December. Also, the name of the book has changed from Using RichFaces to Practical... more »

I’m thinking of doing a 2-day RichFaces boot camp. This assumes you have some basic JSF knowledge and in just 2 days you have a pretty strong knowledge of RichFaces. This can be on-site (private) or public training at any location. I will probably use my upcoming Using RichFaces book (published by Apress) as the basis for this training.
We can do Friday-Saturday, this way we will use only one working day. Another option is to do Saturday-Sunday ??? this way no one has to take any... more »

As my publisher (Apress) is still working on creating a web site for my book, here is a quick overview of that’s going to be in the book.
The official book title is Using RichFaces. The book is a compact guide that covers all the most important components, features and concepts in order to for someone new to RichFaces to quickly start developing with RichFaces. At the same time, someone who has been using RichFaces for sometime will find lots of new useful information as well. ... more »

Understanding the JSF life cycle is very important for understanding how JSF works. It’s also very useful for debugging. For example, if you pass phases 1-3 and then jump to phase 6, this usually means there were conversion/validation errors. Knowing what phases were passed, you need to create a simple phase listener. Here is the super quick way to create a phase tracker.
First, creating the actual phase listener:
