Hi,
you had a very good idea with this plugin!
I tried to install and use the plugin but I got a NullPointerException
(see the stack) as explained in the web page.
Maybe I set the plugin wrongly...
(BTW I did not this: "Carefully javadoc your component classes and
their attributes annotated with @Parameter" )
Hope this helps.

For those interested in using Eclipse code completion with tml files,
EXANPE Team (Julien Maupoux, Katia Aresti and myself) has developped
a Maven plugin that allow you to generate a tld describing any
Tapestry 5 components library.
The plugin uses both Javadoc and @Parameter annotation to perform
the generation.
Once you have generated your TLD, just to configure Eclipse as
described in the Wiki :
http://wiki.apache.org/tapestry/Tapestry5JSPEditorEclipse
This plugin has been tested on Tapestry 5.2 itself (see result TLD
attachment for test completion with core components).
The source code of this plugin is available here :
http://github.com/exanpe/tapestry-tldgen
Informations, usage and notes available here :
http://exanpe.free.fr/tapestry-tldgen/
The plugin has been released as alpha version 1.0.0 and promoting
into Maven central repository.
So, all feedbacks are appreciated (directly on GitHub) !
Best regards,
Laurent Guerin
