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

Roman -

As you know, the direct edit machinery relies on buttons etc being
registered by Javascript called in the <head> element - but your included
stuff is presumably not executable like this, because its <head> element is
not that of the whole browser page.  Would that explain it?  (It's been a
while... I gave up on direct edit some time ago.)

Second thought: session management/cookie problem, though I don't see why
the XMLHttpRequest shouldn't be made by the browser with the same session
cookie presented (unless there's some odd difference in the host part of the
URL).  I guess you could test this by including in the page some kind of
getCurrentProject() call and seeing what the result is - should be
non-online project, of course.

Unfortunately not. There's nothing except some "unidentified entities"
caused as usual by special (german) chars.
