[opencms-dev] Missing element that calls a customizedEventListener

[Martin Lehnert]

Thank you very much for the fast responses... I think the workaround
with the servlet will do until this behaviour is implemented in OpenCms.

Just one note though: The main reason why I want to create this Listener
is because I want to simplify the OpenCms-behaviour when I want to add a
resource in different languages. I think the existing implementation
with saving different languages in one xml-file and the possibility to
switch between them in the WYSIWYG-editor is really great, but clients
find it rather cumbersome to manually add siblings for every
language-version and configure them by adding the right locale property.
Since I understand the necessity to have the different language-versions
accessible through different URLs (for statistic and caching-reasons for
example) I would propose another option in the workplace-context-menu
that automatically creates siblings with an adequate pre- or postfix
(e.g. ISO-locale-code) for every used language-version in the
xml-control code of a resource. This behaviour could also set the
fitting locale-property in the file's properties (perhaps it's even
better to start this behaviour automatically as soon as you save a
resource, while making it possible to deactivate this for people who
don't like this because they want to organize the their
language-versions differently).

This is exactly the behaviour I want to implement through Listeners.
Unfortunately I am to create modules without touching the OpenCms-source
and have a very restrictive deadline, so I have to go the way with
Listeners, otherwise I would program this behaviour directly into
OpenCms and send it to you as a suggestion for incluing it into OpenCms.
When I'm finished, I could send you the code of the behaviour of my
listener, because once this is done I think it would not be too hard to
implement it the way I suggested. As long as you think this idea is
useful, of course.

Greetings and thank you again,
Martin Lehnert
