[opencms-dev] RE: RE: XmlHttpRequest and OpenCms Direct Edit

I know what you mean - it took me a while, and it's so tangled up with
everything else that I can't easily extract code to send you.

Perhaps there might still be some way for you to hook into the OpenCms
direct edit Javascript plumbing - just figure out what's called and why, and
mimic that behaviour through your own Javascript function executed when the
child document has been included.

Another alternative: use asynchronicity when you detect you're in the online
project, but a server-side direct include when you're offline.

Thanks for your suggestions, Jon.

I've tried the following:

Session: Everything's ok. The project is set correctly, CmsJspLoginBean
returns the right values for the logged in values when called inside the
asynchronously loaded "child jsp".

Header JavaScript/CSS: This is most probably the problems source. I've tried
all possible configurations of calling <cms:editable /> (parent only, child
only, parent and child), none of them works.

The only possible solution that came to my mind yet is to code custom
buttons, calling OpenCms XmlContent functionality directly. This is
basically the worst I can think of, so I'd prefer a more common solution.
