Hi,
I am following up on an mail message I made a while back. Specifically,
about support for jx:element tag.
Last I left it, the question was put to the Dev team as to whether we
can actually do this (ie there are no objections to the functionality).
Based on this post [1], I take it there are none. I would really like
this functionality, so I have two questions,
Yep, you are right. I don't have an idea why I thought it was a problematic thing to implement.
Nevertheless, having something like <jx:element/> would be handy.
1. Is anyone working on this?
Don't think so. Anyway, I can help since I have quite good understanding of
Template block.
2. If not, is possible to point me in the right direction so that I can
make this a reality?
If there is no fundamental obstacle this should be very easy to implement. Basically, you need to
checkout cocoon-template-impl[1] module and implement your own template instruction. Have a look at
their listing[2]. You should implement something similar to the jx:out[3] instruction. The name of
element should be obtained from compiled expression similar why jx:out does it.
I have a lot of functionality that relies on the xsp:element tag, and
there doesn't seem to be anything analogous in the JXTemplate world,
which makes moving away from XSPs very difficult (yes, I know I can use
the xmlize, but I would still have to generate the XML in the first
place, which could get messy in flowscript). Also, I have a bunch of
dynamic forms that would probably simplify (a little) with this
functionality.
+1.
If you need any further help don't hesitate to ask. Preferably on dev@ list since this is purely dev
discussion.
