I don't know if this has a solution or is an IDE enhancement, but, when I'm using primefaces components in Netbeans, the autocomplete suggest the taglib p:..., no matter the id is http://primefaces.org/ui (should suggest pou), but if you're using primefaces extensions instead give pe as the showcase, gives poue.
So, now, I created a custom tag lib with id http://zeitek.net/ui, but as extensions is suggested znu, I know I can change it manually, but since is a collaborative project, I would like to use ztk as the predefined prefix to keep the standard in the code, is there anyway to achieve this with a JSF parameter or Netbeans configuration?
Well, if someone need this, i was missing this:
You need to create a tag-lib like normal and add this param:
<facelet-taglib
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
version="2.0"
id="zinf">
<namespace>http://zeitek.net/infraction/jsf/ui</namespace>
<composite-library-name>zinf</composite-library-name>
The last part is the important one: < composite-library-name>zinf< /composite-library-name>

I have a very tricky problem when overriding JSF-renderers.
This is a part of my faces-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
<render-kit>
<renderer>
<component-family>org.primefaces.component</component-family>
<renderer-type>org.primefaces.component.MenubarRenderer</renderer-type>
<renderer-class>de.mycompany.web.MenuRenderer</renderer-class>
</renderer>
</render-kit>
<factory>
<exception-handler-factory>de.mycompany.web.ValidationExceptionHandlerFactory</exception-handler-factory>
</factory>
</faces-config>
The structure of my web-project is following
webapp (building war), Dependencies to core and gui
core (building jar)
gui (building jar), Dependencies to core, containing xhtmls and #Named Beans, Dependency to com.sun.faces:jsf-impl Version 2.1.25
When I place the content of the faces-config.xml in
webapp/src/main/webapp/META-INF or
core/src/main/webapp/META-INF
both, the MenuRenderer and the ValidationExceptionHandlerFactory, are getting used. Yeah.
When I place the content of the faces-config in
gui/src/main/webapp/META-INF
the ValidationExceptionHandlerFactory is getting used, but not the MenuRenderer. WTF?
Also all other features (phase-listeners, system-event-listeners I use in my faces-config are working except ones in the render-kit-nodes.
What am I doing wrong?
You're trying to override a renderer supplied by another external library, not a standard renderer.
The loading order of faces-config.xml provided by external libraries is by default undefined. In your specific case, your library is apparently loaded before PrimeFaces library is loaded.
You can explicitly specify the loading order via <ordering> element in faces-config.xml. The name of the PrimeFaces library is primefaces. So, just add the below entry to your faces-config.xml. Make sure you supply your library a name too so that endusers can in turn reorder in their own faces-config.xml if necessary.
<name>yourlibrary</name>
<ordering>
<after>
<name>primefaces</name>
</after>
</ordering>
A real world example can be found in e.g. OptimusFaces which also extends PrimeFaces.
I've created my own custom myfw:repeat tag for our project as described in JSF ui:repeat in ui:repeat with dynamically assigned var-value and defined it in the myfw.taglib.xml:
<?xml version="1.0"?>
<facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
version="2.0" id="myfw">
<namespace>http://company.at/myfw</namespace>
<composite-library-name>myfw</composite-library-name>
<!-- Other tags -->
<tag>
<tag-name>repeat</tag-name>
<component>
<component-type>at.company.myfw.jsf.component.repeat.UIRepeatForFloatingTable</component-type>
</component>
</tag>
</facelet-taglib>
The tag used in the page is working fine but every time the page is viewed the warning message:
13:03:30,577 WARNING [javax.enterprise.resource.webcontainer.jsf.application] (http-/127.0.0.1:8080-2) JSF1064: Unable to find or serve resource, repeat.xhtml, from library, myfw.
shows up in the logs. This is not just the case with the repeat tag, it also happens to every tag defined in the taglib like ui:compositions. So the log is currently spammed by these messages but the page/tags work properly. A current workaround is to change the log-level, but it is not the desired solution. Using EAP 6.2.0.GA with Mojarra 2.1.19.
This is a bug in Mojarra. It's during Development stage too eagerly logging JSF1064 for tagfiles which couldn't be found in <composite-library-name>, while it should still continue to work through <tag> entries registered directly in taglib itself.
This is not your fault. Those warnings aren't logged in Production stage. I reported this issue as JAVASERVERFACES-3696 (update: this was fixed only a few hours later and will be available as per Mojarra 2.3.0-M02).
It is not so much a question, more of a note.
With Glassfish4, in a JEE7 application I tried to use the flow scope using programmatic flow definition (java class annotated with #Produces #FlowDefinition).
I navigated to the start page of the flow with a h:commandButton (just as it is done in the JEE7 tutorial example https://svn.java.net/svn/javaeetutorial~svn/trunk/examples/web/jsf/checkout-module.
When I pressed the button it stayed on the same page, where the button was, instead of going to the flow's start page.
After many hours of suffering, I realized that the problem is in the beans.xml, in my beans.xml I had this:
bean-discovery-mode="annotated"
which is the recommended setting according to the documentation (http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/beans_1_1.xsd).
When I changed this to
bean-discovery-mode="all"
it started to work.
Somehow CDI does not recognize the flow definition as an annotated class. I tried to make it a #Named class, or a #ApplicationScoped class, but non of these helped.
I don't know if it is the intended behavior, or a bug.
Hope it saves a few ours to someone.
This is related to how CDI detects bean archives. When bean-discovery-mode="annotated", only classes annotated with bean defining annotations are picked up by CDI; note that #Named and #FlowScoped aren't on that list.
Because of this, as you've documented here, using Flow annotations requires bean-discovery-mode="all" to be set.
There's a spec issue open to discuss if this is a desired behavior.
Thank you!
Of course you can always fallback to using an XML declaration for your view. Such as creating a file example/example-flow.xml with contents such as
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">
<flow-definition id="example">
<flow-return id="actionId" >
<from-outcome>#{somebean.returnValue}</from-outcome>
</flow-return>
</flow-definition>
</faces-config>
I am using JSF and I want to use message bundles so I added the XML configuration below. Now I wonder if someone could write some experiences they had when using them. Is it best practice to have one big properties file that contain all translation on the page, if so how do you name your keys. If not, then I guess you have multiple resource files, how do you structure them - what part of the page do they provide messages for? - and any naming practices?
I know this may be subjective but it could be valuable insights for me anyway.
<application>
<resource-bundle>
<base-name>com.myapp.blah</base-name>
<var>msgs</var>
</resource-bundle>
</application>
I suggest you begin with the single File approach, one per language. If it grows in a level that you simply can't manage anymore, thousands of lines, than you might split it.
Then you can internationalize your pages using a template that will have:
<f:view locale="#{userBean.userLocale}">
and you can enable a select component to hold the available languages for the users to switch:
FacesContext.getCurrentInstance().getViewRoot().setLocale(locale);
and in faces-config.xml:
<application>
<locale-config>
<default-locale>pt-br</default-locale>
<supported-locale>en</supported-locale>
</locale-config>
<resource-bundle>
<base-name>com.myapp.blah.ApplicationResources</base-name>
<var>msg</var>
</resource-bundle>
...
then you shall have one file per language:
ApplicationResources.properties
ApplicationResources_en.properties
ApplicationResources_pt_BR.properties
Defining custom components in Facelets is easy and quick but there's one thing I can't figure out.
Is it possible with Facelets to define what attributes my custom component has? I.e: I've created a component which is used in such a way:
<blue:modalWindow id="editFeesWizard" width="500" height="440" title="Wizard">
and is defined in taglib.xml as follows:
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"http://java.sun.com/dtd/facelet-taglib_1_0.dtd">
<facelet-taglib>
<namespace>...</namespace>
<tag>
<tag-name>modalWindow</tag-name>
<source>components/modalWindow.xhtml</source>
</tag>
</facelet-taglib>
Taglib doesn't contain any information on component's attributes (id, width, height, title) and IDE cannot therefore check my syntax nor can it suggest attributes while I'm typing.
I cannot find anything on this subject in Facelets documentation. Thought you could help. Thanks!
It seems there isn't a way. But even if there was, I don't think Eclipse (for example) would be able to handle it and offer autocomplete. That's why you can define a .tld, containing the attributes:
<?xml version="1.0" encoding="utf-8"?>
<taglib
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.1">
......
</taglib>
Just for the sake of autocompletion. Ugly, I know.
I don't know about before, but it is possible now. Just add:
<tag>
<tag-name>mycustomtag</tag-name>
<source>tags/mycustomtag.xhtml</source>
<attribute>
<description>What does this do?!</description>
<name>attribute</name>
</attribute>
</tag>
I'm looking forward to being able to create composite components using JSF 2 and facelets; from what I've read, it seems very quick and easy, and you define what attributes your composite component accepts.
