When using JSF 2.0 & Facelets, a few problem occur in the JBoss Tools Visual Editor.
I'm using 3.2 CR1.
*EL methods with parameters*
When I call a method via EL with parameters (which thus results in a value) an error is
flagged:
http://community.jboss.org/servlet/JiveServlet/showImage/2-584074-11266/e...
http://community.jboss.org/servlet/JiveServlet/downloadImage/2-584074-112...
Because a method is involved, the editor seems to think it's a method expression, but
this is clearly not the case. Even with the == operator no method expression is involved
here. The == operator should even make it more clear the component to which this EL
expression is bound will receive a value.
Needless to say, the code runs perfectly well on JBoss AS 6.
*Annotated managed beans*
When I annotate a JSF managed bean instead of declaring it in faces-config.xml, the editor
does not seem to have any knowledge of the bean. Neither navigate into and auto-completion
work. E.g. if I have the following bean:
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.event.ActionEvent;
@ManagedBean
@ViewScoped
public class MyBean {
public String getFoo() { return "foo"; }
public void setFoo(String foo) {}
}
And a simple Facelet using this bean:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:body>
<h:outputText value="#{myBean.foo}" />
</h:body>
</html>
Then I can't do anything in the editor with "myBean". Here too, the code
runs fine on JBoss AS 6.
*Implicit EL Objects*
The editor does not seem to have full knowledge about the EL implicit objects. When trying
to auto-complete an EL expression bound to a component, e.g. <h:outputText
value="#{...}"/> certain EL implicit objects pop up, but others not.
Available are:
* applicationScope
* component
* cc
* cookie
* facesContext
* flash
* header
* headerValues
* initParam
* param
* paramValues
* requestScope
* resource
* sessionScope
* view
* viewScope
Missing are thus:
* application
* request
* session
Then for some of those implicit EL objects it makes sense to be able to navigate into them
and have auto-completion. This is exactly what the default Eclipse 3.6.1 "HTML
Editor" allows. E.g. navigating into +view+ would bring me to UIViewRoot and
navigating into +component+ would bring me to UIComponent. For auto-completion this is
even more convenient.
Finally, for some reason implicit objects are only available in the editor when I bind an
expression to a component's attribute. If I directly start a #{} expression on a
Facelet and try to auto complete, then no implicit objects show up at all.
*Duplicate tag suggestions*
When I try to auto complete tags, the editor shows me a lot of duplicate suggestions:
http://community.jboss.org/servlet/JiveServlet/showImage/2-584074-11267/d...
http://community.jboss.org/servlet/JiveServlet/downloadImage/2-584074-112...
As can be seen, basically every suggestion appears twice. When I first restarted Eclipse
after the initial installation of JBoss Tools Visual Editor (Richfaces), I even saw the
same ones appearing 3 times. This is not the end of the world, but it does look a little
awkward.
I hope this feedback will be valuable to you ;)
