Specifically HierarchyUtils.__handleBroadcast()). The code counts the number of newly expanded nodes and if it is > 100 then it counts the total number of nodes in the tree and if the total is also > 100, it prevents an expand all and only expands two levels. There are several issues with this:1) This code is executed on every expand/collapse event and can be expensive. Counting 100 nodes in the RowKeySet and in the tree (see TableUtils._getSizeOfTree()) can force the model to do additional data fetches beyond what is currently displayed in the view port. Also the number 100 is completely arbitary. 2) There is no way to for this code to know if the user did an "Expand All" or just did something to cause 100 nodes to expand. For example "Expand All Below", or just select 100 nodes and do "Expand" from a menu. In these cases the user will get unexpcted results (only two levels will expand) 3) Preventing the user from doing an Expand All should really be part of application logic and has no place in the framework. Normally the application would display a warning and ask the user if they really want to do an expand all in response to a user action [Proposal] I would like to propose that this code be removed from UIXTree. I will submit a patch if there are no strong objections. This *is* a change in the Trinidad tree functionality, and I am not sure how it impacts current users. ThanksKamran --- End Message ---

There are a few examples in the shale usecases app [1].
The shale commons validator was an attempt to add client JavaScript validation
to JSF components. Unfortunately, JSF doesn't really give good framework
support for rich client validators that are not coupled to a JSF component
library. The common validator doesn't work with component libraries like
tomahawk and trinidad because the extension points in shale override extension
points in these libraries. I had hoped that JSF 2.0 would address the issue
but it doesn't look as it will. You are best to stick to validators provided
by the component library you are using.

Versioning a DB is not as easy as installing an ear. But, you'd think it would be possible to plug in a JCR like jackrabbit. I don't known how that would work. You might ask on apache jackrabbit.

You can plug in a custom script loaders into a web application that already
uses trinidad. Trinidad uses a resource servlet. At startup, the resource
servlet scanns the class path for
META-INF/services/resources/{url-pattern}.resources. These files define
resource loaders.
Steps:
1) Create a trinidad resource loader by extending RegexResourceLoader.
/**
* This is a composite resource loader that hooks into the
* ResourceServlet.
*
* <servlet>
* <servlet-name>resources</servlet-name>
* <servlet-class>org.apache.myfaces.trinidad.webapp.ResourceServlet
*</servlet-class>
* </servlet>
*
*
* It is registered by placing a text file under
* the "/META-INF/servlets/resources" folder. The name of the file must
* begin with the url folder prefix registered in the web deployment
* descriptor (web.xml) and the suffix should be ".resources".
*
*
*
* resources/acme/*
*
*
*
* The folder prefix needs to correspond to the formulation of various
* web resources.
*
*
* #{facesContext.externalContext.requestContextPath}/acme/images/folder.gif}
*
*
*
*
*/
public class AcmeResourceLoader
extends RegexResourceLoader
{
public AcmeResourceLoader()
{
// any resource in "/acme/" with the following suffixes will be
// loaded from the base folder of "META-INF".
// The servlet pattern match "/acme/*" should exist under "META-INF".
// For example URL : context-root/acme/images/type1.gif
// map to: META-INF/acme/images/type1.gif
register("(/.*\\.(jpg|gif|png|jpeg))",
new ClassLoaderResourceLoader("META-INF"));
// associate pattern match on the "/acme/all-acme.js" to deliver
// all JS files bundled by the AcmeScriptsResourceLoader
register("(/.*all-acme.js)",
new AcmeScriptsResourceLoader("/acme/all- acme.js"));
}
/**
* Aggregates all JavaScript files into a single stream identified
* by a single URI. All JavaScripts for the acme custom component library

*
*
* <script type="text/javascript"

You can plug in a custom script loaders into a web application that already
uses trinidad. Trinidad uses a resource servlet. At startup, the resource
servlet scanns the class path for
META-INF/services/resources/{url-pattern}.resources. These files define
resource loaders.
Steps:
1) Create a trinidad resource loader by extending RegexResourceLoader.
/**
* This is a composite resource loader that hooks into the
* ResourceServlet.
*
*
* resources
* org.apache.myfaces.trinidad.webapp.ResourceServlet
*
*
*
*
* It is registered by placing a text file under
* the "/META-INF/servlets/resources" folder. The name of the file must
* begin with the url folder prefix registered in the web deployment
* descriptor (web.xml) and the suffix should be ".resources".
*
*
*
* resources
* /acme/*
*
*
*
* The folder prefix needs to correspond to the formulation of various
* web resources.
*
*
* #{facesContext.externalContext.requestContextPath}/acme/images/folder.gif}
*
*
*
*
*/
public class AcmeResourceLoader
extends RegexResourceLoader
{
public AcmeResourceLoader()
{
// any resource in "/acme/" with the following suffixes will be
// loaded from the base folder of "META-INF".
// The servlet pattern match "/acme/*" should exist under "META-INF".
// For example URL : context-root/acme/images/type1.gif
// map to: META-INF/acme/images/type1.gif
register("(/.*\\.(jpg|gif|png|jpeg))",
new ClassLoaderResourceLoader("META-INF"));
// associate pattern match on the "/acme/all-acme.js" to deliver
// all JS files bundled by the AcmeScriptsResourceLoader
register("(/.*all-acme.js)",
new AcmeScriptsResourceLoader("/acme/all-acme.js"));

There are several flavors (af:popup, af:popup + af:dialog, af:popup + af:panelWindow and af:popup + af:menu). What's really interesting about the "popup" framework is that all the components exist within the same component tree unlike Trinidad dialogs. The af:dialog and af:panelWindow simulate an external window using div layers. They can operate in model and non modal modes.

The JSF tags invoke the encode methods on the component. The latest version of JSF (1.2) first creates the component tree and then invokes rendering. The JSP tags only create the tree and the tree is rendered using a encodeAll method on the view root by the lifecycle. The Clay example is in between the two JSF versions - implemented prior to JSF 1.2 was drafted. It doesn't use JSP to build the view. If you want JSP to build your view, you will need to dispatch to the JSP after you have replaced the response writer with your own. In your custom view handler, I would try overriding the renderView method while delegating to the original for the other methods. In the renderView, pipe the response writer to a local buffer and use the external context to dispatch to the viewId (JSP page) [1]. Under JSF 1.1 your response writer should be populated with the rendered markup.

The view handler is passed the original on the constructor. You simple delegate to the original when you don't need to override behavior. You need to register your custom view handler in the faces-config.xml [2]. Trididad has a slick extension to the view handler that it calls an internal view. The framework uses it for launching dialogs and other custom views. Depending on what your are doing, it is a simplified API. Internal views are activated by special viewId's. You register these special view Id's in a properties file that is located in the META-INF folder of the web project or a jar [3]. The properties file has to be named "org.apache.myfaces.trinidad.render.InternalView.properties". The key in the properties file is the viewId and the value is the fully qualified classpath to the handler [4]. The viewId doesn't need the URI suffix, "/viewId=com.acme.myhandler". Another method for robbing the response writer of it's content is to plugin your own renderer [5]. Shale Validador does this kind of thing to inject some java script into the rendered markup. The goal was to add script without having to create renderers for every component library that might use the shale commons validator. On the surface, this seems like a good idea but doesn't always work with other component libraries that play the same tricks.

In the JSF Lifecycle, the UIViewRoot processes queued events for each phase by calling the broadcast on the source component for all phases except render response. The components queue events in the decode (apply request values) and can specify the phase they should be invoked in. I believe the default phaseId for the FacesEvent is ANY. In all of these cases, events are processed prior to checking if the response is completed or render response has be set to true. Take a look at the following methods in the UIViewRoot [1]. processDecodes - apply request values processValidators - process validators processUpdates- update model processApplication - invoke application [1] http://svn.apache.org/viewvc/myfaces/core/branches/1_1_5/api/src/main/java/javax/faces/component/UIViewRoot.java?view=markup > Now, doesn't it make sense for a message component to be triggered on > the fact that the command was executed (meaning the button was > clicked, form was submitted) but not necessarily that the JSF action > was run? > > Even if you don't agree, you have to realize that the PPR currently > makes re-rendering impossible if renderResponse is called, shortening > the JSF lifecycle. > > I realize that many people use client side validation with Trinidad > and therefore are less likely to have this issue, but there are > several reasons that client side validation is not a complete > solution. > > With custom components and integration with the Tridindad APIs this > functionality is definitely possible, but it really should be provided > out of the box. > > So to answer your question, there is absolutely no point in > re-rendering a message component if there isn't a validation error or > conversion error. > > -Andrew > Gary > On 8/28/07, Adam Winer wrote: > > I don't understand that sentence...

At least Shale Tiles has some issues [1]. The proposed code, provided in the link at the bottom of the ticket [2], is JSF RI specific which doesn't work for Shale.

Re: [JSF] Custom component - commandLink
It sounds like you need to add the nested component to the component tree.
Try something like this:
HtmlCommandButton b = (HtmlCommandButton) this.getChildren().get(0);
if (b == null) {
HtmlCommandButton b = (HtmlCommandButton)
context.getApplication().createComponent (HtmlCommandButton.COMPONENT_TYPE);
b.setValue("Click me");
this.getChildren().add(0, b);
}
b.encodeBegin(context);
b.encodeChildren(context);
b.encodeEnd(context);
There is a wiki on creating composite components here:
http://wiki.apache.org/myfaces/Creating_Composite_Components?highlight=%28composite%29%7C%28components%29
-- Original message --
From: [EMAIL PROTECTED]
Hi,
I'm developing some simple custom component, and I'm facing a problem I cannot
resolve and understand, so I will really appreciate any help.
I have this piece of code:
public void encodeBegin(FacesContext c) throws IOException {
HtmlCommandButton b = (HtmlCommandButton)
context.getApplication().createComponent(HtmlCommandButton.COMPONENT_TYPE);
b.setValue("Click me");
b.encodeBegin(context);
b.encodeChildren(context);
b.encodeEnd(context);
}
And with above code everything is great, the button renders and when I click
it, the
public void decode(FacesContext context)
method is called... But. If I change HtmlCommandButton to HtmlCommandLink
something strange happens. The link is created and renders as well,
but when I click it, the decode method is not called at all.
Is there any difference between handlig those two components?
Thanks in advance!

We tried something similar for the shale's "commons" validator. This was an attempt to add the ability for a validator to participate in rendering for client-side support. We hooked into the render kit [1] and wrappered renderers of the command [2] and input [3] families. At first this seemed like a great trick but later interfered with tomahawks PPR.

It seems like a lot of extra work to maintain quite a few tr:inputHidden components just to capture selection values. I see what your saying about post-processing a pattern in JS, but I don't think that searching through table for fields might be the best solution :) For selection the Trinidad table has a built-in selection mechanism - tableSelection="single|multiple". Might not be the UI you love best, but it works. It seems like a cleaner and less error prone solution would be a renderer listener that can be invoked in either the encodeBegin() or encodeEnd() methods in the base component. That way a custom component isn't necessary. All I would have to do is set the renderer listener on the link component to process after the link has been rendered, capture the UIParameter values (they will not be null at this stage as they were before the link was rendered), and use them in a JS call to populate the selection input (as described below). I think this approach would minimize the amount of work it takes to implement a custom component, and I'm sure that code execution would be more efficient than adding a new component to the mix everytime that a developer needs some code to execute before/after a component renders. I can see quite a few scenarios where it might be helpful to fire some code before/after any component has been rendered- don't you? Actually, I was imagining one custom component that exposes a generic "before/after rendering" listener API. My concern about adding this to all components is that adding overhead to every component's rendering + state saving performance when only a small minority actually use the functionality is very worrisome.

I've not tried this but I was poking around in the RI source and saw a handy
utility class. You might try something like the following from a callback event
or from a bound component's getter?
String buff =
com.sun.faces.util.DebugUtil.printTree(FacesContext.getCurrentInstance().getViewRoot());
Maybe a phase listener would work for debuging but the best place to hack into
this would be in the ViewHandler's "restoreView" method.
I'd also ask on the Facelets mailing list. They might have a debug option to
view the tree.

Are you using client or server side state saving?
I'm not familiar with the specifics of Facelets but I believe that it is
creating its own jspid to simulate a "JspIdConsumer" and adds it to the
component's attributes. This is how Clay currently works after a few tips from
Jacob. When the component tree is restored, the components that are marked
transient fall out. Transient components have to be recreated and inserted
into the component tree. The "jspid" marker is used to map existing components
to the meta-data used to build the tree.
It sounds like the markup nodes are not being set as transient by facelets or
maybe something in the state saving is not discarding the transient components.
Can you tell if the outputText components that contain the markup "..." are
"transient=true"? What happens if you switch state saving modes?

What happens if you use the output text with the transient attribute?
That would simulate a "verbatim" component that facelets should be using for
inline markup.

And shale declarative xml validation? > You can use shale validator with tomahawk but the sandbox tomahawk code base introduces partial page rendering that doesn't play nicely with shale commons validator [2]. Validators don't participate in page rendering so shale's validator plays some tricks to add behavior to the components renderers. We wrapper the component's renderer. This doesn't work with the new tomahawk PPR because it hides the interface implemented by renderers that support PPR. In the current JSF API 1.x, there is not a pluggable way to make validators (client-side) that work with all components. Besides the need to capture state at render time, there is not a standardized mechanism to deliver client script. As much as I like Shale's integration with commons validator, you are better off using validators offered by a component library that provides client-side validation. Shale solution *tries* to add client-side validation that will work with any component library but I don't think this is available between component libraries. Trinidad offers a pretty slick solution for client-side validator support but you couldn't use one of these validators with a tomahawk component. I believe the standardization of script/resource delivery is on the plate for JSF 2.0.

Component properties are used to fixup the expressions (EL) that JSF uses to bind to data and backing logic. The same component is reused multiple times and its properties defines its behavior. Since JSF is component centric, each component is responsible for acting on the results of a form postback. The components are also responsible for rendering markup. When a post back occurs, JSF restores the component tree for a page. The JSF lifecycle just recursively broadcasts to the component tree starting at the view root. The act of restoring the component tree makes the graph of components realize their behavior. This pattern is similar to commons chains. If you defined a chain that processed the results of a postback, the graph of commands would have to be glued together someplace. Each command might need specific properties for a given path/viewId so that the same command could be reused in various pages. > -Ted. Gary

You many not be using it but it's in your classpath. It might be included

If they are in the classpath, you are using it. Clay would behave the same.

If you are using JSP, the view handler dispatches to the target JSP. The dispatch is a forward that invokes the JSP building the component tree while rendering the document. This logic is in the renderView method of the view handler [2]. externalContext.dispatch(viewId); I don't think you will be able to store the content of the view in a DB if you are using JSP but you might be able to do this using an alternative. With a few modifications, Shale Clay [1] would allow you do store templates in a database. You could store the content as markup fragments or maybe in database tables. I've played with this idea but have not found the interest to take it to the next level. There is a project in the shale sandbox that uses JPA to store metadata that could be used to construct the component tree [3]. This method would be like maintaining an XML file [4] in a DB. Or, maybe the better approach would be to store markup fragments in a DB or better yet a Jackrabbit repository? Clay has a couple parsers that are snapped in to read different types of markup [5].

They call it an InternalView handler. The basic idea is that there is a properties file that you register viewIds [1] that are associated with internal views.

What I'm talking about is meta-data inheritance in addition to composition. This is taken in the context that templates are a meta-data layer that can come from various sources (annotations in the future). Being able to create a composition of components, an address panel for instance, and then extend it adding or overriding widgets. The ability to create a dictionary of reusable visual compositions and have the ability to extend or override.

Indeed Facelets is a popular approach but Facelets is a JSP replacement and
cannot be used within JSP. The core extension point of Clay is a JSF component
which means Clay has more options.
Speaking of options, it is also my opinion that inheritance is one of the core
properties of object oriented programming and has its place within interface
design. Sure, similar capabilities can be accomplished using composition alone
look at DCOM and VB, they are object oriented, after all :-)

You can use Shale Clay to achieve this level of reuse [1]. Clay is an
alternative templating solution that allows you to form JSF page composition
using something other than JSP.
Clay can also be used within a JSP. Clay has something called "symbols" that
are a string substitution layer that is evaluated before a binding expression
is created.
There is a similar address example in the shale-clay-usecases [2].
Consider a fragment from the JSP page [3]:
The managedBeanName JSP tag attribute is a symbol. Its value will be replaced
within the binding expression.
For example:
Within this set of component definitions, "@managed-bean-name" will be replaced
with "rolodex.selectedContact.residentialAddress" or
"rolodex.selectedContact.businessAddress".
Besides the symbol substitution layer, you also have visual inheritance similar
to tiles.
In the JSP example above, the first use of Clay will include the addressPanel.
The second includes the foreignAddressPanel.
Lets first look at the addressPanel.
Next, the "foreignAddressPanel" extends the "addressPanel" adding the province
and country data elements.

You can use Shale Clay to achieve this level of reuse [1]. Clay is an
alternative templating solution that allows you to form JSF page composition
using something other than JSP.
Clay can also be used within a JSP. Clay has something called "symbols" that
are a string substitution layer that is evaluated before a binding expression
is created.
There is a similar address example in the shale-clay-usecases [2].
Consider a fragment from the JSP page [3]:
The managedBeanName JSP tag attribute is a symbol. Its value will be replaced
within the binding expression.
For example:
Within this set of component definitions, "@managed-bean-name" will be replaced
with "rolodex.selectedContact.residentialAddress" or
"rolodex.selectedContact.businessAddress".
Besides the symbol substitution layer, you also have visual inheritance similar
to tiles.
In the JSP example above, the first use of Clay will include the addressPanel.
The second includes the foreignAddressPanel.
Lets first look at the addressPanel.
Next, the "foreignAddressPanel" extends the "addressPanel" adding the province
and country data elements.

Components and renderers are registered in the faces-conifg.xml file. Component renderers (optional) are also registered in the faces-config [1]. Each component [2] should provide a "family". If the rendering is delegated then the "rendererType" should be specified. These values correspond to the "component-type" and "renderer-type" in the faces config. JSF will automatically load "faces-config" files in the "/META-INF" folders and within the "/WEB-INF". You can optional specify additional configuration files in the web.xml. If you are using the component with JSP, you need a JSP tag to instantiate the component and add it to the component tree. JSF/JSP tags act as "factories" versus encapsulating rendering of mark-up. The JSP tag should specify the component type and renderer type [3].

Sounds like you have validation errors. If there are validation errors in the
form,
the lifecycle will stop short. I'd try adding a h:messages component in the
h:form just
to make sure you are not getting tripped up on a conversion error or something.
You could also make the command immediate if you wanted to bypass validation.

Consider:
public void actionListener(ActionEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
Map params = context.getExternalContext().getRequestParameterMap();
params.put("myparam", "value");
// or
ValueBinding vb =
context.getApplication().createValueBinding("#{param.myparam}");
vb.setValue(context, "value");
// or
params = (Map)
context.getApplication().getVariableResolver().resolveVariable(context,
"param");
params.put("myparam", "value");
}

Apparently they both can be used on > UIComponents... > -- There are several significant differences between the two. The f:attribute tag is used to set component's attributes. JSF components have a Map called attributes. This Map has what they call attribute transparency. This means the map looks for a simple java bean property (getter and setter) before adding to the attributes map. You can use this one interfaces to set any of the components attributes. You can also set attributes that are not component properties. These attributes are sometimes used by the renderers and are also saved when the components state is saved. The "f:attribute" Tag is only a JSP tag. It doesn't have a backing component. JSF/JSP tags do not really have anything to do with rendering markup. For the most part, their responsibility is to create the corresponding JSF component and populate the components properties with the attributes within the JSP Tag. The "f:param" tag should only be used as a nested tag under a component for the Command family or the outputLink. It's purpose is similar to the JSTL param tag used with the url tag. The "f:param" tag is used to set query parameters or define request parameters you want to propagate from page to page. Unlike the "f:attribute" tag, the f:param creates a backing component (UIParameter).

It looks like the renderer looks at the content type to determine the type of
markup.
Look at the isXMLDocument method in the HtmlRenderer.
http://svn.apache.org/viewvc/incubator/adffaces/trunk/trinidad/trinidad-impl/src/main/java/org/apache/myfaces/trinidadinternal/renderkit/core/xhtml/HtmlRenderer.java?view=markup

By representing the page with a document component, it is possible to select an alternative renderer for something other than html. This component also renders the CSS for the rich skinning strategy. The component also renderers it's own children. This means that it has greater control over the sequence of renderering. This is used in the partial page renderering.

Ill investigate further but >wanted >to send this email out to the group, just in case someone has already been >through >this path. Thanks. Your error sounds similar to an issue that Shale Clay uncovered. The panelNavigation2 component needs the pages to have similar structure in order to find the components on the previous page. This was a big issue with Shale Clay at one time because it was forcing a naming container. A naming container adds to the component names so that they are unique within a html form. We have since removed this constraint (http://issues.apache.org/struts/browse/SHALE-316) Well, I'm sure that this is all too interesting since it is not about Facelets :-) but, you might check to make sure that your pages structure is the same (meaning panelNavigation2, form, and subview id's). I proposed that the component should try harder to find itself on the previous page with this patch (https://issues.apache.org/jira/browse/TOMAHAWK-755).

I found a nifty mechanism in Trinidad to programmatically build the component
tree.
It's called an InternalView. The internal view is a pseudo view hander that
can be associated
with a specific view id. It looks like Trinidad uses it to build custom popup
dialogs for
some of the components.
I was playing with this idea for Clay/Trinidad integration. These is a testbed
in the
shale sandbox that I've been hacking on.
This implementation just adds a Clay component to the view root and assignes a
template from a query string parameter, jsfid.
http://svn.apache.org/viewvc/shale/sandbox/shale-clay-trinidad/src/main/java/org/apache/shale/clay/PageHandler.java?view=markup
The Trinidad view handler looks for registered internal views by view id. You
create
the mapping by using a properties file that has a constant name and lives under
the
META-INF directory.

Instead of only using jsf property injections, you could obtain your service object in the getter.
This might cover the case where the session fails-over.
public ServiceBean getService() {
if (service == null) {
FacesContext context = getFacesContext(); service = (ServiceBean) context.getApplication().getVariableResolver(). resolveVariable(context, "registrationService");
}
return service;

Clay can be used in JSP or as an alternative to JSP. For example, lets say that our app needed a basic person. That classification of person has a first and middle name. However, in some places in the app, we need a full person that extends the basic persons widgets adding a name prefix, middle name and suffix. To take this a step further, what if we needed a business person that extends the attributes of the full person adding a business name. Clay provides a meta-data layer that it uses to construct a component subtree that is attached to an existing tree. This meta-data is a layer of indirection that gives the ability to use inheritance in addition to composition. The following is an example of the metadata inheritance: allowBody="false"> [EMAIL PROTECTED]}" /> ; extends="basicPersonNamePanel"> extends="fullPersonNamePanel"> This snippet was taken form the shale-clay-usecases exmaple. You can find the rest of the XML configuration here:http://svn.apache.org/viewvc/shale/framework/trunk/shale-apps/shale-clay-usecases/src/main/webapp/WEB-INF/clay-config.xml?view=markup Clay also has something we call symbols. The value attributes in the inputText widgets above contain a symbol, "@managed-bean-name", that will be replaced to reflect the backing bean. Symbols are a substation layer that is evaluated before the value binding expressions are evaluated. This allows you to create a dictionary of reusable view compositions that can be plugged into various pages. In a JSP or HTML template, you might use the above person pannels like the following: Basic PersonmanagedBeanName="basicPerson" /> Full PersonmanagedBeanName="fullPerson" /> Business PersonmanagedBeanName="businessPerson" /> >regards>Matthias Gary

This also means that if you are using client side state saving, the payload will not contain the transient components. Transient components have to be recreated when the view is restored. The verbatim component is a transient outputText component. It generally contains mark-up in your JSP that you don't really need to send to the client in the saved view state.

Sounds like you need to implement the saveState and restoreState in your

restored.

There is not a tag library validator to enforce this yet. The basic strategy that clay uses is to create a meta data layer that gives morereuse options. So, the subtree that clay creates is always from a meta data sourceother than nested JSP tags (symbol tag being the exception).

Just instantiate the bean and inject whatever services/beans itneed via setters. We use Spring, so we often simply autowire backingbeans properties.Testing scenarious for backing beans are quite simple: 1. Initialize the bean (and appropriate dependent beans).2. Set properties.3. Execute the action.4. Check action outcome.5. Check aposteriour values of properties.As for the components, it's a bit more complex. From my point of view there's two things you can/have to test: (a) if the component rendersitself as you want it to be rendered and (b) if what you want to berendered actually works.Testing (a) is not a big problem. Instantiate a component, provide mock/dummy ResponseWriter, render the component and simply check if therendered HTML (orwhatever) is allright. In some of my components I use testing frameworkfrom Shale, it provides a cou ple of useful tools. Testing (b) is much more complex. Okay, from my component I can generatea pile of HTML/_javascript_/CSS, but I need to make sure that alltogetherthis builds, for instance, a working DHTML menu which functions on different browsers.

The JSF jsp tags are not designed to work with other view technologies. Using clay, you can start with a JSP view entry point and expand to a Clay subview but there is not a way to include a jsp from a Clay template.

First a component tree is created starting with a view root. The entire content of the page is kept in JSF components. Then the tree is rendered. Under JSF 1.1, the view is rendered as the tree is built. The markup of the non-jsf JSP tags write to the same writer. This causes problems with components like the dataTable that is trying to inter-weave content with a component and JSP tags output. JSF 1.2 takes the same two step approach but the trick is keeping track of EL that exists in the JSP versus the JSF components. This version has a unified EL engine between JSP and JSF. Pointers to variables defined in the JSP PageContext have to be established for template blocks generated from JSP but added to the component tree as a verbatim JSF components. So, JSP tags should only setup the component tree to be rendered. Even the output markup of non-jsf jsp tags are taken for the buffered writer and stuffed in a verbatim component by the next JSF jsp tag before adding the target to the tree. > Greetings > Chrisi > Gary > > On 5/20/06, Gerald Müllan <[EMAIL PROTECTED]>wrote: > > Hi, > > > > I see the main problem in this that you mix up jsf presentation with > > html markup.

They are markers that are written into the rendered output from the JSF form component. The Form and View JSP tags are required by the JSF runtime. The marker is then replaced with a hidden html input tag that is an encoded serialized representation of the component's state for the page. The JSF view tag does this parsing. This trick is needed in JSF 1.1 because the JSP components build the component tree and invoke rendering versus building the entire tree and then invoking rendering. Since you are seeing this maker in the page, it most likey indicates that the Sun RI Form component added it but the Myfaces View Tag was looking for the other marker. Most app servers are prepackaged with the RI JSF jars that are self registering by the fact that they are in the classpath. My guess is that the JSF RI jars are in the classpath and you have a mix of JSF runtimes. I've seen this with WAS 6 and I just had to delete the RI jars for the servers lib folder.

The "locale$select" is just a managed bean name. I had a Shale examplethat I hacked up for this one. The '$' is a valid character in a managed bean name. It's a default convention used by the Shale ViewController (http://struts.apache.org/struts-shale/features-view-controller.html ).

The in the dataTable nested in the column is used to pass onthe name parameter of the selected student. So, this has nothing to dowith populating the object graph used by the two data tables. It's moreabout how you could provide a way to select a student.
The immediate attribute on the command components just tells the lifecycleto stop short and not perform validation on the widgets in the form. Inthis example, it really is not needed since there is not any UIInput components within the form.
The Student column has a nested datatable that is populated from the ClassInfoobject from the outer dataTable. The getStudent() method is invoked for eachclass object. This can be a hook to build the list for the nested table usingthe primary key of class id.
If you wanted to populate the entire object graph first (list of classes andstudents in each class), you might look at the shale view controller (link above).The ViewCotroller gives you extra lifecycle events such as a "prerender" callback method that is invoked in the managed bean before the view is rendered. This would be a good place to add logic to stage data for the page.
The ViewController is fixed to the page by association of the viewId with themanaged bean name. The managed bean needs to implement the ViewController interfaces or use the shale tiger annotations. The mapping of view id to the managed bean name strips out the '/' chars making them '$' chars andremoves the suffix ".jsp".

-- Original message -- From: "Romanowski, Tim" <[EMAIL PROTECTED]>
Gary, thanks for the suggestion, but I'm not sure I understand how this will help me:
Are you suggesting to use the datalist within my datatable? In such a case, the value returned by "#{countryList.countries}" is dependent upon the row id of my datatable. So I would have several columns in my datatable, of which one of those columns can have multiple 'sub-rows' per datatable row. When I render my datatable, how would I access the current row id in a bean so that I can do a calculation for displaying more data in _another_ column for the _same_ row? Emphasis added since the wording can get tricky.
I could solve this by having two Lists, one which is used for the datatable, and another used by the particular column. I could then synchronize those lists myself, and write some spaghetti to increment a counter every time I grab the data for the particular multi-row column. However, that is a pretty ugly way of handling this, and I'm hoping there is an elegant (or at least less ugly) solution. Thoughts?

How do you guys handle the situation where a given row in a datable might have a column that itself has multiple rows? In other words, row 1 of my datable has a column which itself contains several rows. It doesn't seem like placing a child datatable within a parent datatable will necessarily solve anything, since I don't know what data goes in the current row until I know the value of a column in the current row.
From reading looking through the archives and some other sites, it looks (is this true?) that there is no clean way to pass a parameter of the current row id back to a backing bean to do some processing for dynamically constructing the current row. I've seen some suggestions on setting f:param and using that value, but setting an f:param to equal the current rowid in a datatable doesn't seem to work. I've also seen another kludge that used a 'disabled' property to set a map value, but that was, well, a kludge (but perhaps the best way?).
Again, how are you guys constructing complex tables? Any help would be greatly appreciated!

You could also bind the target component to a managed bean and manually register a converter. Then you could use transparent attributes on the component to pass on to the converter. A custom tag would be the better approach.
The custom attribute would be added to the component.
private HtmlOutputText idCmp = null;
public HtmlOutputText getIdCmp() {
if (idCmp == null) {
idCmp = new HtmlOutputText();
}
if (idCmp.getConverter() == null) {
MyConverter converter = new MyConverter();
converter.setCustom((String) idCmp.getAttributes("custom"));
idCmp.setConverter(converter);
}
}
public void setIdCmp(HtmlOutputText id).

Using the converter in a dataTable will not work this way. The DateTimeConverter's locale property doesn't support a value binding _expression_. The components in the dataTable are created only once and used for all rows.
You could create a custom converter to do this and bind your column outputText to a backing bean to avoid a custom JSP tag. Consider:
JSP:
Backing Bean registered as "locale$select".
private HtmlOutputText output = null; public HtmlOutputText getOutput() { if (output == null) { output = new HtmlOutputText(); FacesContext context = FacesContext.getCurrentInstance(); context.getApplication().addConverter("org.apache.shale.usecases.locale.CustomDateTimeConverter", "org.apache.shale.usecases.locale.CustomDateTimeConverter"); CustomDateTimeConverter converter = (CustomDateTimeConverter) context.getApplication().createConverter("org.apache.shale.usecases.locale.CustomDateTimeConverter"); converter.setDateStyle("long");
ValueBinding vb = context.getApplication().createValueBinding("#{locale}"); converter.setLocaleVB(vb); output.setConverter(converter); } return output; } public void setOutput(HtmlOutputText output) { this.output = output; }
Subclass DateTimeConverter:
public class CustomDateTimeConverter extends DateTimeConverter { private ValueBinding localeVB = null; public void setLocaleVB(ValueBinding localeVB) { this.localeVB = localeVB; } public Locale getLocale() { FacesContext context = FacesContext.getCurrentInstance(); Locale locale = (Locale) localeVB.getValue(context); if (locale == null) locale = super.getLocale(); return locale; } }

In JSF, you will always post back to the same page (view) that rendered the page. The command in the view that was invoked determines where to navigate to. The command is found in the component tree that builds the page.
The ViewController's "prerender" callback method is invoked before the page is rendered. The "prerender" is invoked before the rendering of each component.
When you click on a datatable row commandLink, the view controller "preprocess" callback will be invoked and then the action bound to the command link. This is where you deleted the row and now need to refresh the datatable but you don't have to do that here because the next view controller post back event will be "prerender".
If you are navigating to the same page, the "prerender" will be invoked and a fresh result set loaded.
If you are not seeing the "prerender" invoked after the commandLink on the row, you probabaly don't have a navigation rule back to the same page. This could be why you are not seeing the updated data. The component tree is rendererd with the old state.
Make sure you have a navigation rule back to the resultset page for the delete commandLink.

RE: WebSphere 6.0 JSF implementation change for MyFaces
The only success I've had is to remove the "jsf-api.jar" and "ws-jsf.jar" from the $WAS_INSTALL_ROOT/lib directory. I agree that seems like a hack to have to remove a jar from the WAS 6 base install but I think it's the only way to prevent the "/META-INF/faces-config.xml" in the "ws-jsf.jar" from being loaded. Even if you changed the loader policy, there is not a predefined order that the auto loading of the "/META-INF/faces-configs.xml" are processed. You would still have a mix of RI and myfaces JSF runtimes. Gary -- Original message -- From: "CONNER, BRENDAN (SBCSI)" <[EMAIL PROTECTED]> I'd be interested in that as well. The "official" way that IBM seems to recommend is to use PARENT_LAST class-loading, which will cause the server to look at the classes within the application JAR files before those in the server JAR files. However, this causes other problems with our application, because we only want to override the JSF implementation classes, not *all* of the classes. For now, we're just deleting the two JAR files you mentioned from the server's path, which seems like kind of a kluge. - Brendan -Original Message-From: Pavel Vybiral [mailto:[EMAIL PROTECTED] Sent: Saturday, March 04, 2006 4:39 AMTo: users@myfaces.apache.orgSubject: WebSphere 6.0 JSF implementation change for MyFaces Is there an official way how to change JSF implementation (IBM) in Websphere 6.0.0.0 for MyFaces one.

Re: setting value of attributes like binding, value, validator, converter, and required in java
Clay makes easy work of reusing a view fragment with what it calls symbols.

Re: Running MyFaces on WebSphere 6.0
The classpath probably wouldn't effect the auto loading of the faces-config's. I think this is ordered by the name of the jar. I wonder if they could all live together if you renamed the myfaces impl jar to zz-myfaces.jar so it's registered last? The safest bet would be to just remove the jars. I'm not sure how that would effect their component library. The "inputRichText" is a really sweet control.

RE: [JSF] Tiles and Reusable Template
No, that's the facelets composition mechanism. Using Clay, you would need a separate HTML template for the body. This type of top-level definition works best when you use inheritance so that you can define default symbol value and only override the needed customizations. The templates can also exist in the class path "classpath*:com/acme/templates/body.html". /body.html: mock title [EMAIL PROTECTED]}> -- Original message -- From: "Garner, Shawn" <[EMAIL PROTECTED]> Can I do this? addUserPage.jsp: ...
