New page:
== Facelets Development with IDEs ==

One of the most useful features an IDE can provide for development is auto-complete of methods
and xml tags.

Most IDEs have supported auto-completion for JSP tags for some time. They look in the classpath
for taglib files, then use the information in those files to provide auto-completion. However
equivalent support for tags within facelets xhtml files is not currently nearly as widespread.

=== IntelliJ IDEA ===

IntelliJ IDEA 7.0 has good auto-complete for Facelets files.

IntelliJ is a proprietory IDE; a license is required.

=== Eclipse ===

Eclipse has supported auto-completion for JSP taglibs for some time, but this does not work
in Facelets xhtml files; it only works for jsp files.
With Eclipse (at least up to 3.3.1) there is no support for auto-completion of tags in facelets
files in any of the plugins available from the Eclipse site.

There have been reports that some people have used a jsp:root tag as the root element for
their facelets files to persuade eclipse to use its taglib functionality. As Facelets ignores
all tags outside its ui:component tag this "garbage" does not affect the generated output,
but it is clumsy.

JBoss have recently made arrangements with Exadel to release the code from Exadel Studio Pro
as open source, within the "JBoss IDE" project. At the current date, JBoss IDE plugins are
at RC1, but tag auto-completion works well in facelets xhtml files.

An alternative would be to generate an xml schema from the taglib, then use xml auto-completion
rather than JSP taglib-based auto-completion. The mapping from taglib file to schema requires
just a simple xslt transformation and this would seem to be a good generic solution. Unfortunately
at the current time the Eclipse xml editor is incapable of auto-completion from schemas when
the document being edited has more than one namespace.

Eclipse is an open-source IDE.
