Is there a plan to implement an "Open Declaration" menu that navigates to
the Java class associated with an action or value reference in xhtml?

For example, if document contains a command button like this:
<h:commandButton value="Search" action="#{commentSearch.search}"
id="commentSearchRequest_searchComments" />

and faces-config.xml contains:
<managed-bean>
<managed-bean-name>commentSearch</managed-bean-name>
<managed-bean-class>
mycompany.CommentSearchBean
</managed-bean-class>
</managed-bean>

It would be nice to be able to go directly to the Java code at
mycompany.CommentSearchBean.search() by placing the cursor in the
#{commentSearch.search} portion of the xhtml document, and selecting an
Open Declaration menu.

Digging a little deeper into this, I see there is a context menu to
navigate from the Web Page Editor to the Java action code. For my
project, selecting the Navigate->Java->Action context menu always produces
an error dialog "The value is either an invalid Expression of the
definition is missing."

Since the project builds and executes I doubt the Expression is invalid,
leaving me with "the definition is missing".

The project was originally a Java project. It was later converted to a
Dynamic Web Project. Now I suspect the project needs further tweaking to
add the JSF Facet.

Is there a document that describes migrating a simple Java project to
support JSF?

The project libraries include the following:
Apache Tomcat 6 runtime
Facelets: jsf-facelets-1.1.14.jar
JSTL: jstl-1.2.jar
JSF: Sun Reference Implementation

For the JSF, I have also tried to use the MyFaces jars.

I have created the project two times from top to bottom of the tutorial,
and came up with this error both times.

Does this error "Can't find facelet tag library ..." point to anything
obvious that I'm doing wrong?

What you want works (except this one case, see below) if you hold ctrl
down and mouseover the EL expression, you should get a hyperlink that you
can click to take you to the class or method. It works for JSPs. If you
install the Facelets incubator it will work for XHTML for bean classes and
bean properties. Bean method expressions (i.e. bean.action where the
expression binds to BeanClass.action() instead of
BeanClass.get/setAction()) work for JSP, but I just noticed an outage for
XHTML.

I have launched this bug to track:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=252241

You can CC yourself on the bug to track progress.

Not currently AFAIK. If you find one or want to write/blog one we would
be happy to link for others.

The main steps, as you observe, involve adding the JSF facet (this also
requires adding the Dynamic Web Project and Java facets) and adding the
runtime jars to the classpath (which can be done from the facet install
dialog). To add facets to an existing project, right-click on the
project, select Properties and go to Project Facets in the dialog that
opens.

Thanks,

Cameron

Have you installed the Facelet incubator tools support? This will be
required since Facelets doesn't provide JSP support that would allow it to
work in basic WTP.

Yes. I checked the Help->About->Plugin Feature details menu and see the
feature is installed, version 0.1.0 -- JSF Faceltes Tools - WTP Incubator
Project version 0.1.0.200807291102.

I must have missed a step. I'll try again.
